Evaluating the radioactive contaminations of soil samples in some schools of Mosul province: a health detection

Abstract

In this study, we will investigate the radiation activity of 20 soil samples from five schools in Mosul Province were measured the gamma spectrum by using NaI (TI) Discovery which has dimensions 3*3 crystal. The activity concentrations of naturally occurring of 40K ranged from (310.414±3.40 to 1359.220±1.37) Bqkg−1, 238U reached from (1.035±0.300 to 62.636±0.108) Bq kg−1 and 232Th ranged from (0.583±0.060 to 24.139±0.47) Bq kg−1while the average activity concentration observed 40K was 936.340 ± 3.88 Bqkg−1, 238U was 18.861±0.391 Bqkg−1and 232Th was 5.376 ± 0.312Bqkg−1. The radiological hazard parameters (representative level index, radium equivalent activity, outdoor and indoor dose rates, outdoor and indoor annual effective dose equivalents, and radiation hazard index) were calculated from the radioactivity in the soil. Results of the present work concerning values of radium equivalent activity, outdoor annual effective dose rates, the gamma index, and internal and external hazard indices, all were found to be lower than their corresponding allowed limits given by the world average. The data produced in the present work can be used as baseline radiological data for future investigations.

Natural radioactivity Measurements of Dur-Kurigalzu's Ziggurat, Baghdad Governorate-Iraq using HPGe detector

“…Hassan et al investigated the radiation activity of soil samples from different schools sites in Mosul Province, Iraq using NaI (TI) detector. All results were found to be lower than the allowed world average limits [9]. Ebraheem et al measured the activity concentrations of natural radionuclides and cesium from soil to plant in common different plants species grown at Abu-Ghraib city in the capital Baghdad using NaI(Tl) gamma spectroscopy.…”
