冲绳海槽沉积物中人工放射性137Cs的分布规律
INVESTIGATION OF ARTIFICIAL RADIOACTIVE ISOTOPE 137Cs IN OKINAWA TROUGH SEDIMENTS
【摘要】 <正> 过去几十年中,各国多偏重于海水中137Cs的研究,而对沉积物中137Cs的研究较少。1981年,我们乘“科学一号”船在冲绳海槽区取得了部分沉积物。本文试就137Cs在沉积物中的分布及相关因素作简单探讨。
【Abstract】 The concentrations of 137Cs in Okinawa trough sediments collected in 1981 were determined by 8180-4k multi channel Ge (Li)7 spectrometer. The values of 137Cs are 0-92 pCi/kg·dr.wt.It is discovered that the concentrations of 137Cs decrease gradually with the increase of distance away from the seashore and that of the depth of seawater in Okinawa trough.
