Natural radioactivity concentration of peanuts in Osmaniye-Turkey

Abstract

The peanut is grown in Osmaniye where located in southern Turkey. Due to it is grown underground, the measurements of natural radioactivity of peanuts become important. For this reason some peanut samples have been collected from different places of Osmaniye and the measurements of natural activity concentrations for 40K, 226Ra and 232Th in some peanuts samples have been carried out using a NaI(Tl) gamma-ray spectrometer. Activity of 40K was measured from its intensive line at 1460 keV, for 226Ra activity peak from 214Bi at 1760 keV and 232Th activity, peak from 208Tl at energy of 2610 keV was used. © 2012 American Institute of Physics.
