I don't believe there is any radiation (as in X-rays) to worry about.  There
are many other factors that have not been proven to either have or not have
effect on human beings.

The human nervous system tends to  be effected by external stimuli, such as
sound, light, movement of air, etc.  After all, ears, eyes and skin are in
fact transducers.

If you are new to this subject, I'd highly recommend a book entitled
Health and Light by John N. Ott.  Ott was a pioneer in time-lapse photography
and did some interesting experiments with lighting.  (publisher: Devin-Adair)

With all the talk about greenhouse effects, acid rain, etc., I think we're all
convinced that we humans have an effect on the environment.  It shouldn't take
too much intelligence to figure out that what is in the environment also effectsus.  The ultimate question is not "is there an effect", but rather "to what
degree is the effect".
