离子浓度对生物吸收^（134）Cs的影响

Effect of Ion Concentrations on Absorption of￣(134)Cs by Organisms.

生物对^（１３４）Ｃｓ的吸收量随着时间的延长而增加；Ｋ、Ｎａ离子的浓度显著地影响生物对^（１３４）Ｃｓ的吸收量，但对吸收率影响不明显，吸收量和离子浓度之间呈指数回归关系；当环境中加入Ｋ或Ｎａ盐（肥）时，由于颉颃作用，可以降低生物对^（１３４）Ｃｓ的吸收。

The absorption of cesium-134 by the organisms increased with the time and was obviously affected by the concentrations of potassium or sodium ion,which had little influence on the absorption rates.There was a exponential regression function between the absorption quantities and the ion concentrations. when potassium or sodium salt was added into the system,the absorption of cesium-134 by organisms could he decreased because of the antagonism.
