| Abstract | In the case of U mines containing Th, the total alpha energy will contain contributions from both 222Rn progeny and 220Rn progeny. A simple routine grab sampling monitoring scheme is therefore needed for separate measurement of the working levels of 222Rn and 220Rn progeny. The scheme presented here is based on a short delay period after sampling (2 min) for 222Rn progeny and a long delay period (340 min) before counting 220Rn progeny. An advantage of this scheme is that no corrections need to be made to the 222Rn progeny working level for the presence of 220Rn progeny. Such corrections must be made in the commonly used Kusnetz scheme. |
