A simplified map of natural radioactivity for Mosul city

Abstract

The aim of the present study is to determine the natural radioactivity levels for radon gasin selected samples of some of the environmental elements in the Mosul city of (soil, plantand water) and making map of natural radioactivity for Mosul city using GeographicInformation System technique.The concentration of (222Rn) and (238U) at twelve different regions in Mosul have beenestimated using nuclear track detector (CR-39).The obtained results were entered to the computer in digital form, and it has beenconnected to data entered and stored by geographic coordinates with their spatial locationusing Geographic Information System (GIS). Later on the ArcGIS 10.2.1 Desktop,Erdas9.2 to produce the final maps from the study site.The obtained results show that the lowest concentration of uranium and radon werefound to be: in the Soil sample in Hai 17 tammuz and it is (1.590168 ppm) of uranium and(27324281×103 Bq.m-3) for radon in the air space of the chambers, and it is (17375193×105Bq.m-3) for radon concentration in the samples; in the plant sample in Hai 17 tammuz, and(0.393860 ppm) of uranium and (17264353×103 Bq.m-3) for radon in the air space of thechambers and (17144468×105 Bq.m-3) radon concentration in the samples; in the watersample in Hai Al Ekhaa, and it is (17142:357 ppm) of uranium and (171397163×103 Bq.m-3)for radon in the air space of the chambers, and (171149:28×105 Bq.m-3) for radonconcentration in the samples.The highest concentrations were found to be: in the soil sample in Hai Al moalmen,(2.704451 ppm) of uranium or (37184994 ×103 Bq.m-3) for radon in the air space of thechambers (17562553×105 Bq.m-3) for radon concentration in the samples ; in the plantsample in Hai Al moalmen, (1796326: ppm) of uranium or (17448244×103 Bq.m-3) forradon in the air space of the chambers (17184498×105 Bq.m-3) for Radon concentration inthe samples; in the water sample in Hai Al Faroooq (171954834 ppm) of uranium or (171866::7×103 Bq.m-3) for radon in the air space of the chambers ( 17121396×105 Bq.m-3)for radon concentration in the samples.Almost of these values are allowed globally and their impact on health and theenvironment is not significant. But the important thing that were able to use theGeographic Information System program to draw the map of natural radiation in Mosulcity as a mean for radioactivity monitoring periodically updated.
