关于矿并下作业人员吸入氡子体限值的讨论

DISCUSSION ON LIMITS OF INTAKE OF RADON DAUGHTERS FOR UNDERGROUND WORKERS

摘要: 《放射防护规定》(GBJ8-74)中规定的矿井下氧及共子体的限制标准偏严,根据我国实际情况,井下作业人员吸入氧子体的限值应采用ICRP 1981年的推荐值,即 ALI_P=0.02 J,DAC_P=8.3×10~(-6)J·m~(-3)。

Abstract: The limits for inhalation of radon and its daughters given by Ragulation forRadiation Protection (GBJ8--74) are too strict. For the practices in China, it isproposed that China should adopt the ICRP--recommended values as ALI_P of radondaughters for underground workers. That is ALI_P=0.02J, DAC_P=8.3×10~(-6)J. m~(-3).
