Radioactivity concentration and transfer factors of natural radionuclides 226Ra, 232Th, and 40K from peat soil to vegetables in Selangor, Malaysia

The activity concentrations of naturally occurring radionuclides in vegetables and peat soil were investigated to determine the transfer factors from obtained farms Klang Selangor. results showed that concentration ranges for 226Ra, 232Th, 40K vegetable 2.72-46.54 Bqkg-1, 9.01-54.84 19.22-477.76 respectively. various samples 0.41-3.41 0.02-3.56 16.22-317.49 soil-to-plant 0.01-0.67, 0.00-0.17, 0.26-2.52, Radionuclide has highest factor value most vegetables, especially fruit type vegetable, 232Th was found have lowest all vegetables. acquired compared levels are globally recognized as acceptable. greater than 1 beans showing a similar other studies involving tropical plants, while 226Ra 15 times higher reported data plants.
