| description | This study involves a comprehensive analysis of 226Ra, 232Th, and 40K concentration from irrigation water samples. Water
samples were obtained, and the physical parameters were examined. Subsequently, the corresponding radiological
risks to human health were estimated. The concentration levels of 226Ra, 232Th, and 40K in water samples amounted to
1.51 ± 0.30, 0.17 ± 0.09, and 7.67 ± 3.07 Bq L-1, respectively, which were within the concentration levels reported in the
literature from Malaysia and other countries worldwide. Based on the food intake rate by MoH and UNSCEAR, the
annual ingestion effective dose (ID) and the cancer risks corresponding to radionuclide intake in irrigation were below
the recommended maximum values. Meanwhile, the average hazard indices and annual outdoor effective dose (ED)
amounted to 0.01 and 1.39 mSv year-1, respectively. It was inferred from the findings of this study that the water used
as the sample does not have any significant radiological impacts to human body and is safe to be used as irrigation in
the related area. |
