Re: dental x-rays

It can not be "as a cross-country airplane flight" because in
one case it is the "whole body dose" and in another it is
mostly (at least 95%) a "highly localized dose".

Suppose a dentist allows me to take a dosimeter and that
a dose measured in the mouth is 3 mrem. This is not the
same as 3 mrem received during an airplane flight. Which
one is less desirable? I do not know.

A 1956 textbook I have at home shows that a typical
dose from a chest x-ray exam (one film for an average
size adult) is about 50 mrem in 0.05 seconds.

Do the benefits of frequent dental x-rays outweigh the risks? What would
be the optimum time interval between dental x-rays for someone with healthy
teeth?

Thanks,
