Study of radon levels in fruits samples using LR-115 type II detector

Abstract

Background: Radon concentrations in fruits samples collected randomly from local markets in An Najaf, Iraq has been measured. Materials and Methods: Two passive detector (LR-115 type II nuclear track detectors) were used to measure the radon concentration in 9 fruit samples, in Iran. Results: The radon concentrations measured by both tracks are found to vary from (18.51±8.28 Bq m-3) to (62.96±15.27 Bq m-3) with a mean value of (37.44±5.09 Bq m-3) and from (37.03±11.71 Bq m-3) to (100±19.24 Bq m-3) with a mean value of (55.55±6.83 Bq m-3), respectively. All values of radon concentrations for samples under study were found to be quite lower than the permissible value of (400 Bq m-3) recommended by (ICRP). Conclusion: From radiation protection purpose of read, it had been found that the fruits samples under study don’t cause any vital risk for the presence of222Rn concentration and it’s thought of radiologically safe for human consumption.
