The dose to man from atmospheric 85Kr

The contribution of atmospheric 85Kr to man's dose burden is reexamined. Earlier work is updated and the major dimensions of the problem discussed. Today, the dose ranges from a bare skin dose of approximately 10−3 mrad/yr to a whole body dose of approximately 10−4 mrad/ year. The skin dose is comparable to the whole body dose from natural 3H If the world-wide practice of dumping 85Kr into the atmosphere is not curtailed, these doses will increase by a factor of 30 in the next decade or two.
