Transformation of field monitoring results into miners' annual exposures to radon progeny.

Abstract

This paper presents the theory of estimating miners' radiation hazard, using the values of radon daughters' concentration in the work-environment. All measurement results can be obtained with any technique beginning with instant measurement and ending with long-term dosimetry. The measurements carried out in metal ore mines show that the seasonal changes in radon daughters' concentration have their main influence in the estimation of the miners' hazard. The estimation of the hazard which was obtained from equations, was compared with the results given from the computer simulation.
