Abstract

Environmental radioactivity is an unavoidable phenomenon and is definitely harmful to all living organisms. It is non uniformly distributed in earth’s crust and Kerala is considered as one of the high back ground radiation areas. The present study is initiated with the objective of detecting various radio nuclides present in the soil from five different places in the districts of Thrissur and Malappuram in Kerala, using Scintillation detector Nay(Tl), connected to multi channel analyzer. The samples were analyzed using gamma ray spectroscopic method and the photo peaks from the spectrum indicates the presence of lead (212Pb, 214Pb), actinium (228Ac), bismuth(214Bi) and potassium (40K).
