Radiation Measurement Systems and their Impact on the Estimation of Miners Exposure
This paper presents the results of measurements made simultaneously using different and independent systems of measurement for assessment of miners exposure to radon daughter products. The field grab-air sampling and 'passive' etched track environmental dosemeters were compared with a so-called 'reference system'. Which is based on the individual dosemeters worn by a randomly selected group of miners. This study revels that no correlation exists between the annual miners exposures evaluated using the grab-air-sampling, environmental dosimetry system and the individual dosimetry system. Some regularities were observed, e.g. the effect of 'avoiding' higher concentrations in measurements obtained with the grab-air sampling system usually dominates. The conclusion to be drawn from observation and comparison of these systems is that a correct and true evaluation of miners exposure to radon progeny is very sensitive and dependent on the strategy of sampling and its implementation.
