Evaluation of the radiation dose from radon ingestion from different types of drinking water samples in Egypt using nuclear track detectors (LR-115 Type II): Ahmed Saad Hussein



Radiation Protection and Environment 2019 42(4):168-172



Radon concentrations in different sources of water samples collected from five different regions of Egypt by alpha track dosimetry using LR-115 detectors were determined. The values of radon concentration in water samples did not exceed the maximum level of contamination of 11 BqL−1 reported by the US Environmental Protection Agency and the recommended level of 10 BqL−1 by UNSCEAR 2000. The calculated values of annual effective dose for adults, children, and infants from radon ingested are less than the reference level of 100 μSvy−1 as recommended by the International Atomic Energy Agency, 2002 and WHO, 2009. From these results, it is concluded that there is no radiological risk related to radon ingested from the water samples analyzed in the study area of five different regions of Egypt.
