Evaluation of radon concentrations in drinking water available in Baghdad Governorate markets, Iraq

Abstract

Radon dust was measured in 15 samples Results: The mass of radon in potable water from Baghdad Governorate markets ranged from 3.5 (Bq/m3) to 74 (Bq/m3) with a mean value of 26.6 ±25.311 (Bq/m3). illustrated The annual effective dose (Ed) results for each group (3 months, 10 years, 15 years, and adults). The Ed values for the 3-month age group range from 0.10 to 0.88 μSv/year. as seen for the 10-year age group they range from 0.02 to 0.96 μSv/year; as seen for the 15-year age group they range from 0.13 to 0.98 μSv/year and as seen for the adult age group they range from 0.07 to 0.92 μSv/year Results indicated that the content of radon- 222 in healthy drinking water in Baghdad's market was within permissible limits set by the World Health Organization in 2008 and United Nations Scientific Committee on the Effects of Atomic Radiation in 2000. The annual effective dose of drinking water for infants in Baghdad's market is also within these limits.
