【世界核新闻网站2015年5月21日报道】日本原子力规制委员会(NRA)2015年5月21日宣布,决定将辐射应急人员的辐射照射剂量率上限从100 m Sv/a提高至250 m Sv/a。这一决定将从2016年4月开始生效。日本曾在福岛核事故应急工作中临时性将这一上限提升至250 m Sv/a。通常情况下,核工业人员允许的剂量率上限为20 m Sv/a,虽然他们在实际工作中受到的剂量率远低于这一水平。如果在任何一年达到这一上限,这名工作人在该
[World Nuclear News website reported on May 21, 2015] The Japan Atomic Regulations Commission (NRA) announced on May 21, 2015 that it decided to increase the radiation dose rate ceiling for radiation emergency personnel from 100 mSv / a to 250 m Sv / a. This decision will take effect in April 2016. Japan had temporarily raised this upper limit to 250 m Sv / a during the Fukushima nuclear accident emergency work. In general, the maximum allowable dose rate for nuclear industry personnel is 20 mSv / a, although the dose rates they receive in practice are well below this level. If this ceiling is reached in any year, the worker is there
