Reading this link you would think that there was no danger whatsoever with radiation. Life traps uses radiation to perform its many functions. Microwave ovens without metal inside do one thing and with metal inside do another. Metals are key to life processes and mitigate the physics environment that seemingly harmless radiation travels into. The scientific medical and biophysical discussion really needs to be opened up otherwise we could all die from cancer threshold from ultraviolet light or as the case may well be from the effects on unfortunate people from man made and distributed willy nilly electronic stuff we don't even begin to understand.
To say a technology is safe when you disregard the complete evidence is criminal! Do we let people live shorter uncomfortable lives because the majority feel its safe and ok. Mankind has made this mistake many times before as commercial demands outweigh prudence.
