Abstract  

The study of the Nicotiana rustica variety from North Bengal, revealed that the respective amounts of radioactive nuclei40K,90Sr,90Y and rare earth activity as well as210Pb were found to be 4.04, 2.42, 4.52, and 0.052 pCi/g of cured leaves. In another investigation with Nicotiana tabaccum variety from Rajahmundri, Andhra Pradesh, contents of40K,90Sr,90Y and rare earth activity, and210Pb were observed to be 4.06, 1.02, 3.44 and 0.20 pCi/g of cured leaves, respectively. Results indicate that the amount of polonium which is presumably in equilibrium with RaD in these two varieties of Indian tobacco leaves is very small. Detailed studies on different varieties of Indian tobacco are in progress.
