Those college kids made up that website as a dig at the breathless scare mongering by so many ecofreaks. The whole site is a sendup of that silliness. I find it very humorous. 😊 Ghery S. Pettit From: Ken Javor Sent: Thursday, July 5, 2018 2:05 PM To: EMC-PSTC@LISTSERV.IEEE.ORG Subjec

Those college students¹ knee jerk reaction to a scientific name for a life-sustaining chemical is a perfect example of what I was saying below. Over-the-top, but very apropos. College students. Soon we will be at the point where a non-technical college degree will be a negative incentive to hire s

Ghery "Thanks" for that link - seems like we should all stop drinking/using WATER. Then just die of thirst and/or malnutrition and/or illness due to lack of basic hygiene! ;) Just goes to "show" that almost EVERYTHING (including thus EMF!), in "life" comes with "risks" - but didn't we all a

Hi Ken and the group, Ken you make very good points! One interesting point. Heart disease and arthritis are, for the most part, nutritional deficiency diseases, easily avoided if one knows what one is doing, which most do not. It is not possible to get adequate amounts of required

Another chemical that is a problem in certain cases is Dihydrogen Monoxide. See www.dhmo.org for more information. BTW, for those of you who are challenged by chemistry, DHMO is also known as water. Ghery S. Pettit From: Ken Javor Sent: Thursday, July 5, 2018 1:

Re: [PSES] EN62311 - Human Exposure to Electromagnetic Fields

The precautionary principle, as harmless and common sense as it sounds, is at the root of much mischief. Said mischief is not inherent in the principle itself, but how it is used. Since anyone can come up with a ³what if ³scenario, the principle ends up applied indiscriminately. Just as John Woo

Re: [PSES] EN62311 - Human Exposure to Electromagnetic Fields

There is another aspect to this, the 'precautionary principle'. This says that if you don't know the harmful level of something, you reduce its level  to ALARP, 'as low as is reasonably practicable'.  Unfortunately, of course, opinions differ very widely on what that level is, in many cases. Th

Re: [PSES] EN62311 - Human Exposure to Electromagnetic Fields

Yes, there are very big 'safety factors' built into the requirements, more in Europe than in USA. Much of the interest in Europe was generated by Scandinavian trades unions concerned about 'radiation' from CRT displays. Adverse health effects of a general nature(headaches, insomnia, general mal

Hi Michael and the group, With the exception tissue heating generated by some sources at very high frequencies, I wonder if the EM field exposure worries today are a bit overblown. I started my experiments in high voltage  (100,000+ Volts, and NOT static electricity) around age 13 a

Re: [PSES] EN62311 - Human Exposure to Electromagnetic Fields

It's not quite an "unintentional radiator" but if you had a wireless charger which did not contain any communication (e.g., a dumb charging signal without handshaking), then it would come within the scope of the EMCD and the LVD (not the RED), and RF Exposure would therefore be an issue under the

Re: [PSES] EN62311 - Human Exposure to Electromagnetic Fields

Be surprised if any LVD could cause EMF large enough to pose a danger to Human Health. Intentional transmitters maybe, a rare beast to create those levels unintentionally at less than 1000V. Andy From: John Woodgate [mailto:j...@woodjohn.uk] Sent: 05 July 2018 10:28 To: EMC-PSTC@LISTSERV.IEEE.O

Re: [PSES] EN62311 - Human Exposure to Electromagnetic Fields

The frequency range is DC to 300 GHz, so power frequency magnetic fields are included. Some household appliances used to produce quite strong fields very close to the casing. Historically, bulk erasers for magnetic recording tape produced strong magnetic fields. The requirements include large '

Re: [PSES] EN62311 - Human Exposure to Electromagnetic Fields

It applies to any LVD product, but there is a flow chart that shows that a simple assessment is possible if the product has no reasonable likelihood of producing sufficiently strong EMF. John Woodgate OOO-Own Opinions Only J M Woodgate and Associates www.woodjohn.uk Rayleigh, Essex UK On 2018-
