摘要:
为了研究核素在近海域迁移中各因素的影响,本文采用理论分析方法,建立了大气核素干、湿沉降分析模型,并建立了悬浮物对放射性核素吸附沉降模型和海洋生物富集模型,给出了各因素的影响程度。结果表明:干沉降通量比地面核素浓度低3~4个数量级,湿沉降通量比干沉降通量大2个数量级。悬浮物对放射性核素的吸附沉降率随沉积通量、分配系数和作用时间的增大而增大;分配系数为104 L/kg和生物量为10-5 kg/L时,生物富集使放射性活度减小了10%左右。短期核素扩散中,源项、对流扩散、干湿沉降和半衰期较短核素衰变影响较大;长期核素扩散中,源项、半衰期较长核素衰变和悬浮物影响较大;生物富集影响一直很小,可以忽略。
