Radon gas is considered as a main risk factor for lung cancer and found naturally in rock, soil, and water. Therefore, researchers around the globe continue to monitor and measure its levels to continuously assess possible levels in order to take prevention measures in case the gas concentration gets out of the permitted tolerance. Hamzeh Al Zabadi et al.'s paper is one of the aforementioned studies whose aim is to determine the radon level in the drinking water sources in Nablus city in order to set up a sound policy on water management in Palestine. The authors are commended for their scientific endeavor showing sound research practices whereby they followed a systematic and well structured approach relying on experimental data and attempted to describe their findings by comparing to international standards and benchmarking the USA. The researchers sampled several wells from which the city of Nablus tap water pertains. Their findings show that measured radon concentrations in the wells and springs were below the USA EPA maximum contaminated level (U.S EPA MCL). The level was much lower for tap water. Although the concentration of radon in the tap water of old city were below the MCL, it was higher than other regions in the city.

This research is an eye opener not only to researchers in Palestine but also in other Arab countries. Findings help local authorities to take preventive measures and create population awareness on radon’s exposure. However, it is recommended first to create a study reflecting comparative data from all the regions in Palestine. Another very important study is to carry out the same in Gaza Strip which was highly exposed to chemicals and other poisonous compounds due to the heavy bombardments by the Israeli forces during their several attacks in the last decade.
