Yshield: New scam artist flogging ‘EMR shielding paint’
Tuesday April 10th 2012, 6:15 pm

For as long as there’s been new technologies, there’s been scam artists ready to take money from people who have irrational fears about them. This phenomenon dates at least back to the introduction of home electrification, which was quite mysterious to many at the time.

More recently, scammers have flogged fears about mobile phones purportedly causing cancer- and it’s been investigated over and over and over, with sample sizes in the tens of thousands and sampling periods of more than a decade. Not a single proven case of radio signal induced illness- of ANY kind, cancer included- has ever been recorded.

With the introduction of ‘smart’ power meters, the ignorant are again being exploited:

HAVE YOUR SAY: Just not what an Ormond doctor ordered

9 Apr 12 @ 12:01am by Jesse Wray-McCann

AN Ormond doctor has had her home painted with electromagnetic shielding paint because she says smart meters in her street are making her ill.

Federica Lamech said she could not work due to debilitating health problems caused by smart meters – even through she did not have one in her own home.

Dr Lamech said she had suffered continuous palpitations, chest pain, lethargy, dizziness, fainting and insomnia since the meters were rolled out in her area in February.

“I am not able to function,” Dr Lamech said.

YShield Electromagnetic Radiation Shielding general manager David Mould said it had painted hundreds of houses since the smart meter rollout began.

“We’ve done four houses this week, in Ormond, East Bentleigh and St Kilda,” Mr Mould said last week.

“Demand is so high we’re having to book jobs weeks in advance.”

She has taken sick leave from her Aspendale Gardens GP practice.

“I can’t work, I can’t look after my family and I need my husband, now the only breadwinner, to take care of me,” Dr Lamech said.

Stop Smart Meters Australia spokesman Marc Florio demanded the State Government follow the lead of the UK Government, which was reportedly planning to make smart meters voluntary.

Government spokeswoman Emily Broadbent said the meters were safe and their radiofrequency emissions were weaker than many other household devices.

Ms Broadbent said the World Health Organisation determined electromagnetic hypersensitivity was not a medical diagnosis.

Wow. A GP, no less, has been conned by an outfit called ‘Yshield Electromagnetic Shielding Technologies‘ into painting her home with ‘electromagnetic shielding paint,’ which Yshield claims has only carbon and no metallic matter in it.

First of all, any device with a microprocessor in it will have a circuit called a ‘clock oscillator’ in it. Clock oscillators generate extremely low level electrical pulses in the radio frequency range.  These pulses are used by the microprocessor to time the execution of lines of code which make digital widgets do what they do. Everything from pocket calculators and digital watches/clocks to TV sets as well as desktop, laptop and tablet computers have clock oscillators. ‘Smart meters’ are no different. Even with highly sensitive receiving equipment, the radio emissions from a clock oscillator are difficult to detect from more than a few centrimetres away.

Second, there’s absolutely no evidence whatsoever that radio signals- including extremely weak clock oscillator signals from calculators, watches and WiFi, to the very weak signals from mobile phones, the much stronger signals from microwave ovens to the very strongest RF sources you’re likely to find on earth, those being megawatt-level TV transmitters- cause ANY malady. ‘Electrosensitivity’ is completely imaginary, despite the hordes of unscrupulous ratbags (often on the internet) trying to sell cures and/or mitigations to salve this imaginary malady.

If you REALLY want to block radio signals- and there’s good reasons to do so, particularly if you are working with  sensitive electronic equipment that may not function correctly in the presence of stray RF fields (such as when performing an alignment on a radio receiver), you need what’s known as a ‘Faraday cage.’ A Faraday cage is normally made from brass screening or other highly conductive material that is connected to an earth ground.  There are paints around that will, to some degree, limit passage of radio signals, but all of them have highly conductive metals in them- but none of them will reduce RF field strengths unless connected to ground via a low-impedance path.

The nonsense being sold by Yshield is highly likely to do nothing at all, and worse, to solve  a problem that doesn’t exist.

If you believe you need RF shielding paint, could I interest you in my tiger-repelling rocks? See any tigers? Of course you don’t!

If someone wants your hard-earned dough to ward off those scary radio signals, they’re a scammer, plain and simple.

OH SO TRUE !
I have been working with RF since I was a child.
My Grandfather was the design engineer for Radio Australia in Shepparton, my father did Radio Australia in Carnarvon WA after cyclone tracey made short work of the Darwin one.
My Family for generations have worked with RF at levels up to 100 Mega Watts, transmitting 1/2 way around the world.
My Grandfather died in his late 80’s, my Dad is a very fit and healthy man in his late 70’s now and all of us have been exposed to RF radio signals that make Flourescent lights glow without power applied.

The levels coming out of devices like mobile phones and smart meters is tiny compared to that of a two way CB radio in a car or house that many RF enthusiasts use, let alone the Radio and TV stations that transmit across the country.

The RF radiation is everywhere, even in the far outback of Australia, you can listen to the radio.

LIVE WITH IT, the rest of us do.

Thanks for that, Lindsay.

There’s a number of scaremongers driving fears of mobile phones, baby monitors etc. and now ‘smart’ power meters. I have a couple of objections to smart meters, mainly regarding privacy and artificially raising electricity costs, particularly for pensioners and disabled people who are home at all hours, but quite clearly, I don’t have any objections to radio emsissions from the things.

It’s one thing for people to have valid concerns and to have questions answered. It’s quite another when imaginary medical conditions with no basis in scientific evidence are blamed on some sort of unprovable corporate or government conspiracy.

You and I both have been involved with high-strength RF fields for decades. I got my amateur radio licence when I was about 14 and worked as a radio broadcast engineer for yonks. I worked with shortwave transmitters up to 150kW, broadcast band FM transmitters in the 50kW class and broadcast band AM transmitters in the 10-25kW neighborhood- and like you, your father and grandfather, am cancer-free. However, all our experiences still are only classifiable as anecdotes. Finding out whether there’s any sort of hazard from RF takes serious epidemiological and statistical studies- and there have been a couple of very large ones done, accounting for tens of thousands of people over decades of RF exposure- and no statistically significant relationship has yet been found.

Merits mention that there are now some 6 BILLION mobile phones in service- but no correlating increase in cancers. In fact, the coy wag who draws the nerd-comic xkcd even surmises that cancer causes cell phones!

The whole ‘electromagnetic radiation!!!’ scare hinges upon the public perception that there’s only one sort of ‘radiation’ and it’s all the sort that you get from radionuclear materials like uranium and plutonium. The ‘true believers’ and scaremongers refuse to accept that non-ionising radiation is not a hazard. Mind, these are the same goobers who think fluoridated water is some sort of gubmint mind-control plot…

This all would be hilarious if there were not scammers like Yshield & Lyn McLean beating up irrational fears so they can make a profit by selling RF field strength meters and so-called RF-shielding paint to the people whom they’ve scared witless. This is pure con artistry and ought to be illegal. At very least, when you search Ye Goog for ‘Lyn McLean,’ the top ranked result is a post right here on mgk.

I’ve been hoping for some years that McLean would arc up and sue me for calling her a charlatan and a scammer. No such luck- yet, anyway, though I’m quite sure she & her flying monkeys have seen my comments. I would dearly love to get her into a courtroom and make her prove her utterly specious claims. However, like any smart con-artist, she’s avoided such a confrontation, simply because she knows damned well that it would put her right out of business.

Thanks for stopping by!

Y-Shield’s web site has some pics of their EMR readings they say are “high” at 146 milliwatts per sq metre. But the standards specify milliwatts per sq CENTImetre. So a reading of 146/m2 = 0.0146 milliwatts per sq m. Doesn’t seem so high now!

I think this guy is a crook preying on the ignorant.

Comment by Jim MacConnell 06.04.12 @ 3:30 pm

Good point Jim. However, since there’s no evidence that RF/EMR at typical levels is in any way harmful to humans, what Yshield measures (or erroneously measures) doesn’t matter one iota. Mr Mould was a crook preying on the ignorant before he put a single “measurement” on his website.

At this moment, I think it’s appropriate to direct gentle readers to the ACCC’s Scamwatch website.

Comment by weez 06.04.12 @ 4:33 pm

Wackoliar of the moment:

The WHO has classed Smart Meters as carcinogenic

False.

studies show that people who live near or under power lines are affected

Total bullshit.

Two lies in one comment? BAM! Bitbucket.

Comment by weez 08.02.12 @ 1:11 pm

oh, and- Wackoliar insists that if there’s a lot of crazy people who post something about their imaginary symptoms on the internet, those symptoms suddenly are provably linked to radio signals.

Wrong again! Thanks for playing.

Does the Y-Shield paint actually work to block electromagnetic interference?
I only ask because when I moved into my new apartment, my electric guitars are picking up a loud buzzing noise. Stew Mac sells shielding paint for the electronic cavity area’s, so obviously that works. But at $60 a pint, it is not economical to paint the floor with.

Comment by survivor030406 11.13.12 @ 12:50 pm

Nevermind, a guitar guy on amazon confirms that the product does indeed work.

Comment by survivor030406 11.13.12 @ 1:38 pm

Y-Shield claims that their paint contains carbon particles, which will not reduce RF field strengths. As you note, there are paints that will provide RF shielding, but they contain conductive material like copper and/or zinc. You wouldn’t just have to paint the floor with it, you’d have to paint every interior surface, including windows.

Your ‘guitar guy on Amazon’ is having you on.

Comment by weez 11.13.12 @ 2:29 pm

I’m sure the noise is 60hz, from power mains. Guitars are notorious for picking up 60 cycle hum, especially where the ground is bad. I’m not getting any radio noise here.
So this paint will not block 60 cycle hum from old electric house wiring? I will test the outlet on Wednesday.

Comment by survivor030406 11.13.12 @ 5:21 pm

Nope, Y-Shield won’t block any electromagnetic or radio frequency interference, let alone 60hz.

Check your amplifier for poor solder connections or bad power supply filter capacitors. The cord which connects your guitar to your amp may have poor shielding or a broken shield to ground connection. Try a different cord. You can isolate where the problem might be with a spare 1/4″ plug with all conductors shorted to ground plugged into the amp input. If you still have hum, the problem is in the amp or its power supply, may even be in the house wiring (poor ground connection).

Comment by weez 11.13.12 @ 5:32 pm

I think it’s the house wiring. I will get an outlet tester. I’m predicting some type of fault will be found. One outlet doesn’t even work. I’ve tried 3 amps, 3 guitars, 2 cables. Same buzzing no matter what. But there is no doubt that an electromagnetic field also has a lot to do with it because a guitar near the floor, the buzzing is LOUD, holding a guitar over my head, the buzzing is quieter. Hence picking up noise not from any amp itself. Maybe a faulty ground at the outlet is compounding the problem. At this point I am wondering what an electrician would charge to fix the house wires. There’s no way the landlord will pay for it. And I don’t want to be stuck here and not be able to enjoy some music practice. I will get the shielding paint from Stew Mac and shield inside the guitar cavities. I will post what the results are tomorrow from the outlet test. I am not going to mess with outlet wires myself. Getting an electrician for hopefully a simple affordable fix, I should be good to go.

Comment by survivor030406 11.14.12 @ 10:19 am

I think you’re right about the house wiring. 60Hz intrusion into amplifiers means that the filtering built into the power supply is either not working or can’t discharge the 60Hz energy to ground.

You can paint the guitar cavities with all the shielding paint you like but if there is not a good, low-impedance path to ground, the hum will remain.

The landlord is foolish if s/he doesn’t sort out grounding problems- that’s a liability issue that can very easily come back to bite them. If there’s a poor ground connection in the house wiring, you will find that there’s about 60VAC on metal chassis of appliances with more than enough current to present a nasty, if not lethal shock hazard. If the landlord refuses to repair, you’re within your rights to abandon the lease as the landlord has failed to provide a safely habitable premises.

Comment by weez 11.14.12 @ 10:29 am

Fault isolation in 60Hz buzz problems can be challenging given the nature of VLF signals. One thing I might suggest before you go calling in electricians is to test the guitar & amp in another premises. If the problem disappears in another premises, then I’d consider bringing in the sparkies.

Comment by weez 11.14.12 @ 10:45 am

Hey, would you know, how hard is it to install a new ground?

Comment by survivor030406 11.14.12 @ 11:27 am

wait.. the date shows as tomorrow, so 16 hours ahead? strange.

Comment by survivor030406 11.14.12 @ 11:40 am

Not particularly difficult to add a new ground connection, but the existing one should be made to work properly.

The timestamp is set for the location of this blog’s author- eastern Australia.

Comment by weez 11.14.12 @ 12:19 pm

I tested the outlet today using GB GRT-3500.
It said the outlet is correct.
But something isn’t right with this much noise.
My guess is that the wires are not run through metal conduit. I won’t be ripping out the floor to install that. I’m not sure what I can do now.

Comment by survivor030406 11.15.12 @ 10:01 am

Full conduit is not required for hum-free operation, just a solid ground connection (aside from properly operating equipment).

Need to isolate where the hum is entering the amplifier. Have you tried shorting the amp input to ground? Different cord? Tried using the guitar/cord/amp in another premises?

Comment by weez 11.15.12 @ 10:19 am

I touch a piece of metal (trem bar)to the input end of the cord and the noise goes away, touch to the tip (hot) the noise gets louder.
I’m pretty sure that is normal, as the strings on a guitar with passive electronics are connected to ground.
I have a guitar with active EMG 81/85 pickups. There is no ground according to EMG. Should I do some wort of test with that too?

Comment by survivor030406 11.15.12 @ 10:31 am

You need to be methodical in testing to isolate the entry path of the hum.

1) Take an old 1/4″ plug (or one end of an old patch cord with an inch or so of cable left on it), short all conductors together as shown:

and plug it into the amp input. The amp should be free from hum even with gain all the way up. If you get hum, the problem is either bad power supply filter capacitors inside the amp, a poor connection somewhere inside the amp or a poor connection from the amp chassis to ground. All 3 pins should be present on the wall connector of your amp’s AC line cord- sometimes the gnd pin gets cut off (by silly people) to suit older ungrounded AC mains wall sockets in the US. If the gnd pin has been cut off, replace the AC mains power cord on the amplifier.

2) If you get hum with the input shorted to gnd, try the amp, with the input shorting plug installed, in another premises. This will isolate the cause to either some fault inside the amplifier or to the AC mains wiring in your rental property.

3) If you get no hum with the shorted 1/4″ connector plugged into the amp’s input, plug your usual guitar patch cord into the amp input and short the conductors on the 1/4″ plug on the other end of the cord together. A wrap of copper wire (or aluminium foil) connecting the tip to the ‘ring’ as shown will do:

If you get hum with this arrangement, the patch cord is faulty. Replace the patch cord.

4) If you get no hum with your patch cord which has had one end shorted, but you do get hum when the patch cord is plugged into the guitar, the fault is in the guitar pickups or wiring inside the guitar. Try a different guitar. If a different guitar produces no hum, then investigate the wiring in your usual guitar. Resolder any dodgy connections. If that doesn’t fix it, you may need to replace the pickups.

The “Biosafety Report by Cindy Sage” is a bucket of bullshit. Reading pseudoscientific nonsense on Google for a few hours is NOT ‘research.’

Comment by weez 12.24.12 @ 10:45 pm

I know I’m very late into the discussion, but one thing has truck me in weez’s discourse (and I had to get it off my chest): you need to block radio signals when working with very sensitive electronic equipment, but not for a human body…? (only the most sensitive piece of equipment known on this planet!)

Comment by Gosia 08.29.13 @ 4:40 pm

You do have to use a Faraday cage when calibrating radio receivers- but the human body is all but completely insensitive to radio signals. There’s no evidence whatsoever that human “electrosensitivity” exists. No person claiming the affliction has ever been able to accurately determine when a radio signal generating device is turned on or off.

The only effect from human exposure to radio signals is heating- and exposure to radio signals at the levels used for communications produces tissue heating so minimal that it’s indistinguishable from statistical noise. You get an awful lot more heating effect from standing near a wood stove. In fact, the amount of heating you experience from infrared emissions from a 100W incandescent light bulb at 100m away is comparable to the heating you experience from a mobile phone at 1cm away. If you’re worried about 100W incandescent light bulbs 100m away, then by all means- go ahead & panic about mobile phones.

You’re all so smart. But as a very smart physicist told me once – how much “power”, is in a thought. NOT MUCH. THOUSANDS of times – less – than the measurable power levels of the current emf environment. So, the power levels being blasted about, could EASILY, be affecting and overwhelming the thought, of anyone.

No doubt you guys are all geniuses, but tell me this, how come in the 50’s cancer was around one in 50 people but now it’s one in 3 people will get cancer in there life. I’m not suggesting that EMR is the only thing to blame but you shouldn’t be so closed minded to think you know everything.

1) Your “1 in 3 cancer” figures are wrong
2) If you live long enough, you will develop some kind of cancer
3) Non-ionising radiation is not mutagenic. Minimum particle energy for mutagenic effects is 1eV. Non-ionising radiation (eg radio signals) is maximum .000001eV or 10^-06 the energy level required for mutagenic effects.
4) Man-made radio signals have been emitted since the 1880s
5) Brain cancer levels have remained stubbornly flat despite the introduction of 6 BILLION mobile phones into the environment since the early 1990s. No correlation at all. Why?
6) The earth has been bathed in both ionising & non-ionising radiation from the sun for about 4 billion years.
7) Go away and play with your conspiracy theory loving mates, I’m not interested.

Agree the paint merchants are less than ethical BUT the bottom line is ( I’m delighted to stand corrected ) is that you, or no one knows the precise effect of waves on atomic ‘communication’ waves in DNA replication. After all the bottom line is cancer is nothing more than polluted atomic sequence caused by corrupt ‘wave’ ( bonding ) communication. So I’d keep and open mind until it’s proven these DNA frequencies are known and proven 100% not to be influence by larger wave frequencies.

‘DNA frequencies’?! ‘DNA communication waves’?! Hilarious!

6 billion mobile phones introduced into the environment since 1993 and no even remotely corresponding health effects. No lines out the door at cancer clinics, no mass graves filling up with ‘victims’ of radio signals.

No one’s else DNA appears to be as sensitive as yours. What makes yours so special?

My strong advice to you is that you wrap your entire body in silver-plated brass screening, silver soldered at all joins, and connect it with 25mm welding cable to a 2.5 metre long copper rod driven into moist earth.

Then, and only then, will your ‘atomic DNA frequencies’ go unmolested by the barrage of radio signals in which this planet has been bathed for lo these last 4.54 ± 0.05 billion years from our local star and the billions of others in all our neighbouring galaxies.

Would like to take this opportunity to mention that the computing device you’ve used today to decry the effects of ‘frequencies’ on DNA is happily percolating away with its clock oscillator, CPU, GPU & other associated widgetry emitting a steady stream of non-ionising radiation. I will see to it that you are granted a VC for braving the DNA corrupting hazards of said device to warn me and everyone else of the corruptive effects of ‘frequencies’ on DNA. Il est donc très courageux de ta part!

Surely tests must have been carried out before the seller could start selling RF shielding paint? Either that, or the GP should have thought about asking first!

Considering there is no evidence for health hazards from radio signals, be they from mobile phones or any other source, it doesn’t really matter whether efficacy is tested or not, does it?

‘EMR shielding paint’ is snake oil. It is sold by con artists who first scare the wits out of underinformed people. The hucksters usually also sell radio frequency field strength meters which may indeed show the presence of a radio signal, but if there’s no evidence there’s any harm from said signals- what’s the point? It’s a scam, no more, no less.

I have for many years been daring con artists to sue me for calling them con artists but I’ve had no takers. There’s a very good reason for this- in a courtroom, the huckster would be compelled to produce scientific evidence of the harm their product is supposed to protect against- and quite obviously, none can do so.

I hope you haven’t been taken in by the scammers. If you have, I hope you can get your money back.
