随着我国环境科学的发展和环境保护的需要,提出了包括海洋环境在内的污染调查的迫切任务.海洋放射性是海洋污染调查的重要内容之一,现已提出了许多重要放射性核素的各别分析方法.但是在环境普查中待分析的核素相当多,普遍采用个别测定方法缺点很多:如耗费大量的分析样品,方法消耗试剂较多,费时长等.采用几个核素联合测定的方法,可在相当程度上克服上述缺点.本文是对海生物样品中~(60)Co、~(55+59)Fe、~(65)Zn联合测定的研究.~(60)Co、~(55+59)Fe、~(65)Zn是中子核反应产生的放射性核素,是核试验的落下灰、原子能设施和核舰船排放的废水中的重要组成核素.它们进入海洋后,除了污染海
With the development of environmental science and the need of environmental protection in our country, the urgent task of pollution investigation including the marine environment is put forward.Immunity radioactivity is one of the important contents of marine pollution investigation. Nowadays, many important radionuclides However, in the environmental census, there are a lot of radionuclides to be analyzed, and there are a lot of disadvantages in using the individual measurement methods generally, such as consuming a large amount of analytical samples, consuming more reagents, taking longer time, etc. Using several radionuclides in combination (60) Co, ~ (55 + 59) Fe and ~ (65) Zn in the marine biological samples were studied in this paper. 55 + 59) Fe, ~ (65) Zn is a radionuclide produced by the reaction of neutron nuclei and is an important constituent of nuclear waste in nuclear waste, atomic energy facilities and nuclear warships. After entering the sea, Pollution of the sea
