Fortunately or Unfortunately depending on if you were one of those that got used as the test subject. Radiation is one of the few areas that have really been studied hard. 1940's-1950's with Gee aren't we nice our own soldiers as the test subjects.
Lots of Alpha, Beta and Tons of Gamma, Long term studies?? I don't think many subjects had a good time in their later years.
Up to about 10 - 20 years ago the exposure limits were based on the banking system, Ie for every year over the age of 18 you were alotted 5R, and worse it accumulated, a 20 year old was allowed up to 10R, 22yrs - 20R etc.
Todays regs alot each adult over 18 5R per year. Period.
Course I'm in the buisness, so I am biased, but I figure 5R a year is pretty conservative and I can live with it. Heh Course in 10 years of doing this I've got a lifetime of less than 7R. I'm a firm believer in avoiding as much as I can.
