据报道,2011年3月至2012年4月期间,在距离福岛第一核电站约250公里范围内的监测站测量了每月的铯 - 137沉降量。2011年3月至6月期间,各监测站的每月铯 - 137沉降量以11 - 14天的表观半衰期下降,2011年7月之后其下降速率发生了变化。每月铯 - 137沉降量的第二个峰值出现在2012年2月至4月,这可能是由于含铯 - 137颗粒的再悬浮所致。(C)2013爱思唯尔有限公司。保留所有权利。
Monthly Cs-137 depositions from March 2011 to April 2012 were reported at monitoring stations within about 250 km from the Fukushima Daiichi NPP. The monthly Cs-137 deposition at each station decreased with apparent half-lives of 11-14 d during the period from March to June 2011, and after July 2011 its decrease rates changed. Second peaks of the monthly Cs-137 deposition occurred in February-April 2012, which may be supported by resuspension of Cs-137 bearing particles. (C) 2013 Elsevier Ltd. All rights reserved,
