Default radar and health ? digressing to keyless remotes...

Steve,

Your assertion is simply not correct. You may be thinking of particle
radiation, such as electron (beta), neutron, proton, alpha, cosmic,
etc., but pure photon radiation can certainly be "ionizing". A
well-known example is ordinary medical x-rays. Ionizing photons would
not typically be called "RF", but there is no difference other than the
energy levels.

(I spent so much time in the early stages of my career dealing with
intense sources of ionizing radiation (photons) that I still glow in the
dark.)

Back to the original question, ordinary radar is clearly not "ionizing".
Not a good idea to be too close, due to possible thermal effects, but
otherwise no big deal.

First, There are two "kind" of RF radiation, non-ionizing and ionizing and
effects emanating from very high voltage nearby different materials.



*** Perhaps a typo, but the ionizing type is not a kind of RF
radiation. Ionizing radiation is nuclear radiation. This radiation is able
to strip electrons (and other particles) from atoms. RF does not do this as
we use it. It is unfortunate that we use the term "radiation" for both
things. In any case, it is not part of the original question.
