There is continuing debates about "Non-Ionising Radiation" and the safety issues; although more particularly for cell phones and urban emitters rather then DECCA RADAR and DECCA Navigation emitters (note DECCA is the Chinese work for RADAR, comes from the British company that pioneered DECCA navigation). Non-Ionising Radiation is the kind of Radiation that does not strip Ions from bio-chemical bonds unlike other more harmful radiations like Gamma, Nuclear Radiation. RF radiation waves are Non-Ionising, however specific frequencies can be more readily absorb by some parts of the body then others. This is to do with resonant frequencies for body tissues and the one quarter wavelength in the RF wave it self. The rate of absorb-ion is known as the SAR (Specific Absorption Rate). The general recommendations are not to stare directly into RF beams or expose soft tissues for very long periods of time and short ranges to the emitters. Some medical practitioners believe that some frequencies ha ...more
