Concentrations Radon in Water for Distribution Water Stations in Duluiyah city / Salah-Din

Abstract

In this research was measured radon concentration in 90 samples of water in 15 different distribution Water Stations in Duluiyah city/Salah-Din Governorate/Iraq. We used (RAD7) was average $^{222}\text{Rn}$ concentration and the maximum concentration in S13 (0.336) Bq.L-1 and minimum concentration in S3 (0.124) Bq.L-1, the annual effective dose was (0.602) mSv.y-1. The mean annual dose rate in the studied models was less than the allowable rate for WHO and USEPA which is equal 1mSv.Y-1, Therefore, the studied models can be considered safe from the radiological aspect, especially radon.
