Radon Concentrations and Risk Factors Evaluation in Iraqi Museum and Al Mustansiriya Old School in Baghdad Using CR-39 as a Solid State Nuclear Track Detector (SSNTD)

Abstract

The current study reports radon gas measurements (Rn) levels of concentration in indoor air at various locations of the Iraqi museum and Al-mustansiriya old school which were conducted using a solid state nuclear track detector (SSNTDs) technique. The samples were randomly distributed over twenty different locations in the Iraqi museum and Al-mustansiriya old school. Radon concentrations (CRn) and risk factors (PAEC (mWL), EP (WLM Y-1), AED (mSv /y) and cancer of the Lungs per 106 person) were calculated, the values of radon concentration were high in the basements (ground floor) and poor ventilation locations (A7 and B1), while the average radon concentration was equal to 168.27±5.89 and 231.88±3.03 Bq/m3, (AED) 5.5±0.32 and 8.32±0.13 mSv/y, (CPPP) 154.63±2.16 and 184.21±1.86, (PAEC) 45.84±1.70 and 39.14±1.31 mWL and (EP) 0.93±0.036 and 1.53±0.022 WLMY-1 in Iraqi museum and Al-mustansiriya old school respectively, all these values are within the permissible limits recommended by the ICRP.
