本文介绍了三个地勘局14个地质大队男性职工全死因分析结果。调查了1956—1986年间累积的426021人年,共死亡956例。给出了十类死因别死亡率,前六位单死因死亡率。井下作业人员吸入氡子体所致累积平均照射量为119WLM,外照射累积有效剂量当量平均为0.037Sv 相似文献

采用固体径迹法对中国辐射防护研究院室内外氡水平进行了调查,并估算了室内外氡子体及外照射所致成年人有效剂量。结果表明,室内外氡浓度平均值分别为33.6Bq/m~(-3)及13.7Bqm~(-3),平衡因子F值分别为0.4及0.54,室内外氡子体照射所致成年人平均年有效剂量分别为0.93mSv及0.19mSv,γ外照射致年有效剂量分别为0.55及0.08mSv,总年有效剂量1.75mSv。 相似文献

The dose distribution in the lung is inhomogeneous.The dose to the basal cell layer of trachea and main bronchi is much higher than the dose to total lung both for rabbits at different ages and for different animals.A maximum value of the dose to lung tissue for rabbits at ages of 20-40d is observed.The dose decreases with increasing body weight.The relationship between the dose and body weight can be descreibed by a power function.The dose to total lung increases exponentially with the minute breathing volume per unit of lung weight. 相似文献
