Portable ENG
We just got these in and have been wondering what, if any, hazards there may be. There are many internet sites you can go to but it all boils down to "we don't know".
Below are some sites that might help.
Here is the short version of what we are telling photogs..... We transmit at the lowest level ( 1/10 watt) with the antenna about 9 inches away. The most common problem with microwave energy is that it heats the body. At 9 inches, you should limit your exposure to about 6 minuets each transmission. After an equal amout of "down" time you can transmit 6 more minuets. If you move the antenna further away (UP) you can gain more transmit time (one of the internet sites will give you information on this) Two areas of the body are more susseptable then others ... your eyes and nads ... they have a lower blood flow and do not remove heat a readily. We are also advising our female staff that they should avoid this equipment if the are pregnant... We are looking to be extra safe here. No info about it just trying to be protective. There is one study, done by the Russians, about 6-7 years ago that showed tumors in rabbits. This has not been able to be duplicated. The W.H.O. commisioned a study in 2003 but there are no results.
One sign of low exposure is
A burning sensation on your skin (like a sun burn)
Some signs of over exposure (LONG TERM OR VERY HIGH LEVELS OR BOTH)
Fatigue - Forgetfulness - Painfull Joints - Cataracts - Sever Head Ache

This is good information with many references for more research.
