Cumulative dose measurements using radiophotoluminescence glass dosimeter in cold area

摘要: Environmental cumulative doses measured by a radiophotoluminescence glass dosimeter (RPLD) and thermoluminescence (TLD) were compared at the same monitoring points during two years. In winter season, when mean temperature of dropped below 4 °C, RPLD-sensitivity offered approximately 5% lower values in comparison with those other seasons. From artificial irradiation experiments under different room temperatures, sensitivity RPLD was found to decrease 3-4% 6.3 while difference negligible above 8 °C. Based on present results, much attention should be paid changes RPLD, whenever used cold areas.
