^(125)I对农作物污染的研究

STUOIES ON ^(125)I CONTAMINATION TO VARIOUS CROPS

本文研究了^(125)I对玉米、小麦、大麦等5种作物幼苗,及植物叶片,卒孕—抽穗期水稻,结荚期大豆,抽穗期冬麦,开花期豌豆等的污染。结果表明,在相同污染条件下,各种植物幼苗被污染的水平不同,^(125)I可由污染叶片向新生叶片、豆荚、根部转移,也可由茎表面横向转移至内部,^(125)地可由土表向深层移动。

The contamination of 125I to various crops such as corn,wheat ba-rley,soybean,pea,and rice etc.was studied.The results showed that under the same conditions the degree of 125I contamination varied with the different kinds of crops and materials used.125I absorbed by the leaves could be transfered into newly grown leaves,pods and roots.125I on the surface of sterns could be horizontally transfered into internal tissue.125I on the soil surface was also able to transfer to the deep layer of soil.
