Abstract
The study conducted in Jericho and Al Aghwar Governorate, Palestine, aimed to assess the concentrations of Radon (222Rn) and Radium contents (226Ra) in 54 drinking water samples collected from various sites. The can technique, utilizing Solid State Nuclear Track Detectors (SSNTDs) with CR-39 detectors, was employed for the measurements. The average radon concentration ranges from 228.9 (0.23) to 2260.3 Bq/m3 (2.26 Bq/ℓ) with a total average value of 875.7 Bq/m3 (0.88 Bq/ℓ). The average value of radium contents varied from 11.1 Bq/kg to 110.1 Bq/kg with a total average value of 42.6 Bq/kg. The recorded concentrations of 222Rn were found to be below the action levels established by both US EPA and EU recommendations, which are set at 11 Bq/ℓ and 100 Bq/ℓ, respectively. However, it is important to note that these concentrations exceeded the maximum acceptable limit specified by the WHO, which is documented as 0.4 Bq/ℓ (400 Bq/m3). Consequently, the study concludes that consuming water from the investigated area, either for drinking or cooking, is deemed safe and does not pose significant health risks.
