Activity concentration and transfer of 210Po and dose due to consumption of the velvet bean, Mucuna pruriens (L.) DC. var. utilis (Wright) Burck.
Journal Title: Bioscience Discovery - Year 2017, Vol 8, Issue 1
Abstract
The activity concentration of naturally occurring radionuclide 210Po were determined in Mucuna pruriens (L.) DC. var. utilis (Wright) Burck. collected from three different locations of Kanyakumari District. 210Po activity concentration in velvet bean were estimated in poded, depoded and soil samples. Activity concentration of 210Po in plant and soil were measured by employing alpha radiation counting system. Maximum activity concentration of 210Po (0.84±0.08 Bq/kg) recorded in bean+ pod samples collected from Puthalam, whereas lowest activity concentration (0.09±0.01 Bq/kg) recorded in bean samples collected from Pallam. Transfer factor (TF) values were maximum in Puthalam site (1.23). Total annual commited effective dose to the public was found to be 2.81 to 4.68×10-7 µSv/yr from depoded bean sample and 12.17 to 17.47×10-7 µSv/yr from poded bean sample.
