Abstract

In 1962 and 1963 determination of Sr-90 and Ca in some foodstuffs and fodder of vegetable origin was carried out. Analysis of the results obtained has led to the following conclusions:
1. Grass (hay, lucerne) is for the most part contaminated by surface contamination.
2. The degree of surface contamination of hay and lucerne is comparatively higher in spring than in summer vegetation owing to a higher radioactive fallout in spring.
3. The activity of lucerne is somewhat lower than the activity of hay because the roots of lucerne go deeper into the soil and are therefore less exposed to indirect contamination.
4. The plants with a lower Ca content take a proportionately lower content of Sr-90 from the soil. This is extremely important for the articles contaminated through the soil, because the amount of strontium and calcium taken by the plant from the soil is in an approximate relation to the amount of these elements dissolved in the soil.
