1.1.2 RADAR Safety – Radiation
There is no international agreement about the danger posed by high frequency radiation of the kind
produced by the radar systems. In most countries, a radiation density exceeding 100 W/m
2
is
considered dangerous; in some countries, values over 10 W/m
2
are regarded as not being
completely safe. If in doubt, observe the applicable local regulations, and always ensure minimum
possible exposure.
