The main health effect of exposure to electromagnetic radiation is:
burning of the skin
heating of tissue
evaporation of water
mutation of genes
Guidance on safe levels of RF radiation is not available from:
the Goverment and International bodies
HPA – Health Protection Agency
Ofcom
ICNIRP- International Committee on Non-Ionising Radiation Protection
It is unwise to look down a microwave frequency waveguide because
Waveguides are made from metals that if heated by RF energy could produce toxic gases
These have high level of gain meaning that if the transmitter is turned on the body could be exposed to dangerous levels of RF radiation
The high levels of RF could cause a heart attack
The high voltage on the waveguide could cause a high voltage flash that could electrocute the observer
Which of these would it be most dangerous to stand in front of?
A dipole with a gain of 0dB fed from a 50 Watt transmitter
A 10 element beam with a 12dB gain fed with 20 Watts from a transmitter
A 16 element beam with a gain of 18dB fed with 10 Watts from a transmitter
A 5 element beam fed with a 9dB gain fed from a 50Watt transmitter
Which of these would be the safest from the point of view of RF radiation
Running coax past the operator's head from a 400 Watt transmitter into a resonant dipole
Running 300 Ohm twin feeder past the operator's head from a 400 Watt transmitter into a resonant dipole
Running the end of a quarter wave long wire past the operators head from a 400 Watt transmitter
Running 600 Ohm open wire feeder past the operator's head from a 400 Watt transmitter into a resonant dipole
