The activity concentration of radionuclides such as 226Ra, 228Th, 238U and 40K were determined in vegetables cultivated in a high
background radiation area, Midalam, situated in south west coast of India. The measurements were carried out using a 3?
x 3? NaI gamma spectrometry. The radionuclides activity of 226Ra, 228Th, 238U, 40K in soil and vegetable samples were also studied
collecting samples at 10 sampling points around Midalam. Maximum activity was found in (carica papaya) Papaya and (Moringa
oleifera) drum stick compared to the other vegetable samples. The transfer factor for 226Ra, 228Th, 238U and 40K were estimated. The
radioactivity concentration and the relative dose were found below the permissible limits.
