Behavior and effects of radionuclides in soils and plants
The effects of K and Ca on the uptake and distribution of Sr and Cs in whole corn plants have been investigated. The inhibitory effect of K upon uptake of Sr by excised roots applies equally to whole plants. Calcium, as in excised roots, inhibits total uptake slightly but significantly increases retention by the root. Potassium has a small stimulatory effect upon the absorption of Cs by the whole plant and reduces root retention. That is, K promotes upward transport of Cs. The effect of Ca upon Cs uptake and distribution is similar to its effect with regard to Sr. The lability of Cs absorbed by the root is lowered by Ca. Uptake of Cs by the whole plant is lowered by Ca. Uptake of carrier-free /sup 137/Cs by intact tomato leaf samples was found to be extremely variable. The results of field experiments on the effects of beta radiation on bush beans, barley plants, and pea plants are reported.
