Abstract:

2011年4~6月在中国海采集了海水样品,用低本底g能谱测定了海水137Cs活度,旨在评估福岛核事故对中国海、特别是对东海的影响.在观测期,中国海137Cs活度为0.75±0.07~1.43±0.08Bqm-3,平均值为1.12±0.08Bqm-3.东海表层137Cs水平分布在内陆架最高,沿岸和外陆架均较低;在垂直分布上,137Cs在表层最高,并呈随深度逐渐降低.这种分布特征主要受控于137Cs大气沉降输入以及随后的决定于不同水团间的混合效应.针对东海而言,137Cs在水柱中的储量为93Bqm-2,大气输入通量为5.4~42.9mBqm-2d-1,平均为32.2mBqm-2d-1,在东海的停留时间为45~95d,平均为66d;总体而言,福岛核事故对东海137Cs的影响小于切尔诺贝利事故,其输入的总量对东海的影响不显著.
