Whole body counting of radon daughters.

摘要

This paper reports the initial work in a series of experiments involving experimental exposure to radon and radon daughter products in an exposure chamber. Five adult males were exposed for one hour to radon and radon daughter products in an exposure chamber and were subsequently measured for radon daughter product activity in the chest region by whole body counting methods. About half of the deposited activity was associated with internal deposition and half with external deposition on clothing, skin and hair. A substantial contribution was made to the counting rate from deposits on under as well as outer clothing. A strong but statistically non significant correlation was found between internal and external deposition indicating that total activity provides an index of internal deposition. 2 refs., 3 figs., 4 tabs.
