Abstract
A technique for monitoring the average alpha exposure due to the airborne decay products of radon-222 in a uranium mine atmosphere was described. Sampling was done on a long term continuous basis. The plan involved the collection of a long term, high volume sample, in which the short lived daughters decay to lead-210 (14255040). These rapidly separate and a liquid scintillation counting technique was used to count the lead-210. During actual testing, while countable quantities of lead-210 were accumulated, only a fraction of the activity could be attributed to the direct collection of short lived daughters. The remainder of the lead-210 was shown to result from a variety of indeterminate background sources. According to the author, these findings raise serious questions concerning the usefulness of measuring accumulated levels of lead- 210 whether it be on an air filter or in a blood sample from miners and assuming that it relates directly to radon exposure.
