Abstract
The {alpha}-particle activity associated with Long-lived Radioactive Dust (LLRD) samples from an underground uranium mine has been measured. The {alpha}-particle activity measured on mine air samples has been related to the amount of silica dust collected on the samples, determined by X-ray diffraction analysis. The long-lived {alpha}-particle activity was plotted against silica dust content in the samples. A linear relationship with reasonable correlation coefficient was found which can be expressed by the equation A - mW{sub 0} + b, where A and W{sub Q} represent the {alpha}-particle activity (mBq) and silica dust mass (mg) in the sample, respectively. Because measurements of LLRD are time-consuming and expensive, the study was aimed at obtaining a useful relationship between the two variables to enable calculation of LLRD {alpha}-activity from silica dust measurements, the latter conducted on a routine basis by our laboratory for the mine under consideration. Recommendations for further studies are indicated. (23 figs., tab., 7 refs.).
