The mean gross alpha and beta activities in vegetables at Koottumangalam in Kanyakumari District were determined. The radioactivity studies were carried out in the Health Physics unit of BARC located in Indian Rare Earths Limited, Manavalakurichy in Kanyakumari. The vegetables such as Mango, Coconut crunch, Lady’s finger, Cucumber and Brinjal were taken for alpha and beta activies determination. The average gross alpha activities for vegetable were found to be 1.25±0.019 for mango, 1.41±0.014 for coconut crunch, 0.81±0.018 for lady’s finger, 1.05±0.025 for cucumber and 0.92±0.019 Bq g-1 for brinjal and their beta activities were 3.45±0.44 for mango, 3.75±0.014 for coconut crunch, 2.05±0.24 for lady’s finger, 3.05±0.44 for cucumber, 1.97±0.44 Bq g-1 for brinjal. The result of the average gross alpha activities for vegetable were presented and discussed in detail.
