Abstract

The tapioca grown in the regions of southern Kerala has been studied to estimate the content of natural radioactivity in them, using a PC based multichannel gamma ray analyser. It is found that the thorium content in both soil and tapioca are comparatively high. The observed uranium content in tapioca is almost insignificant. The concentration of potassium is much higher in tapioca than in soil which is possibly due to passive absorption and retention by the roots. (author). 3 refs., 2 figs.
