| 摘 要： | 氡及其子体累积探测器是一种氡及其子体的个体α累积暴露量测量装置。它是将固体径迹探测理论和方法,用于α剂量监测的一项新成果。 由于放射性矿山(包括非放射性矿山中遇到氧问题〕的开发以及有关的环保工作,都要求对于氡及其子体的危害做出评价,因此,个体α剂量监测便成为急待解决的问题。 氡及其子体累积探测器,它不但可以测量10~(-10)Ci/l以上水平高浓度的氡,而且可以测量居民区环境大气中的氡,如10~(-13)Ci/l水平。

| Abstract: | This paper introduced a plastic track detector. It was applied for measuring the cumulative expoure of radon and its daughters in mine and environment.According to the maximum energy loss of a particles in polycarbonate plastic the sensitive volume of detection can be increased. First the plastic foil is corroded and then we get magnified tree tracks with electrical chemical etching, the corresponding expoure was determined from the measured track densities.The detectors were calibrated in a laboratory radon chamber. The calibration factor has been measured to be 11 tracks/cm2-WLH, depending on equilibrium factor F. The low limit and upper limit of the detection are 0.5 WLH and 50 WLM, respectively. |
