文摘
Groundwater of Wadi Nu’man (30 km southeast of Mecca city) of high radon-222 (\({^{222}}\)Rn) content, emanated directly from the bed rock into the water reservoir, has been analyzed for lead-210 (\({^{210}}\)Pb) and polonium-210 (\({^{210}}\)Po), the comparatively long- lived \({^{222}}\)Rn progenies, to study the effect of the continuous \({^{222}}\)Rn emanation on the accumulation of both radionuclides in this water. Emanation of \({^{222}}\)Rn directly from rock to water may be affected seasonally by atmospheric temperature and pressure; therefore, \({^{222}}\)Rn and \({^{222}}\)Rn progenies were reanalyzed in seasonal samples of the same wells. The obtained results showed \({^{210}}\)Pb and \({^{210}}\)Po activity levels ranging from <6 to 29.9 and from 0.6 to 18.2 mBq/L, respectively, which was far below the recorded level of their parent radionuclide \({^{222}}\)Rn (10.9–99.7 Bq/L). The data have been discussed in detail.
