Re: 226 Radium Inquiry
November 2, 2003
It seems to me that the radiation detection conversion factor for Ra-226
depends on the radon retention fraction which is a function of surface
binding and chemical factors. Most of the alpha, beta and gamma radiation
may come from the decay products of radon depending on its retention
factor. Hence, there is no single all purpose conversion factor for Ra-226
surface contamination.
