FCC Electromagnetic Exposure web page with new Amateur Radio MPE requirements

[w1vtp]

Ran across this during my job.  Part of my antenna measuring activities require documentation of a safe RF environment.  FCC has a document that pertains specifically to the radio amateur.

General page

Specific document regarding safe RF environment from Amateur Radio transmisions:

http://transition.fcc.gov/Bureaus/Engineering_Technology/Documents/bulletins/oet65/oet65b.pdf

Generally speaking, mobile installations with the antenna on a metal roof is considered exempt from compliance requirements (see page 4).

As responsibile operators of radio transmitters we should be aware of Maximum Permissable Exposure limits (MPE) that have been established by the electrical engineering community and that are regulated by the FCC and the states.

The only valid physiological effect produced by RF exposure is tissue heating which is caused by a field strength and energy level (i.e. frequency) all but a handful of hams won't encounter.  IOW, you just about have to try to produce any causal effect from RF.

Well when we had that Class M Exposure yesterday what kind of hazard was that..?
I understand what it is and where it came from but what did we Humans absorb..?

Did I miss it or were ther no SAR calculations done?

Somehow I feel this is kind of like PEP power measurments.  Doubt if the engineers will be running around with a tape measure unless someone really peaves them.

The guys running EME high power stations on those microwave freqs should think about this.
HF below 10M, you can hug the antenna at QRO.

anything less then 200V/M is candy A$$

What about those low, 6' (+/-) diameter transmitting loops? They can be made very efficient, and the RF field around them is really high.

I'm thinking of building one, and have a page started about them at http://www.w0btu.com/magnetic_loops.html.

I bet a resonated loop would make quite the field. I would not use it in the house with any QRO power
