【摘要】 ⁵⁹Fe是核电站排放废水中含有的放射性核素之一。本工作以⁵⁹FeCl₃为指示剂,配成污染液,研究⁵⁹Fe在不同生长期的水稻植株中的积累与分布特征,及在水稻体内和不同土壤类型中⁵⁹Fe的积累动移规律;讨论了同一污染量,一次性或多次性污染对⁵⁹Fe在水稻体内及土壤中分布以及对水稻生长的影响。最后,根据⁵⁹Fe通过土壤间接进入农业生态环境的生物学后果,提出了处理和利用农产品的可能途径。更多还原

【Abstract】 The 68Fe is one of radionuclides in the waste water discharged from nuclear power plants. The accumulation and distribution of B8Fe in rice plants at different growing stages and the accumulation and migration in soils of 昫ifferent textures were studied by using solution containing 6SFeCl, as a tracer. At the same contaminated activity,the effects of irrigating frequencies of containing 68Fe water on rice growth and distribution in the soils were 昫iscussed.According to the biological consequences caused by 69Fe entering indirectly into agroecological environment, the possible methods for treatment and utilization of agricultural products were suggested.更多还原
