A simplified map of natural radioactivity for Mosul city

The aim of the present study is to determine the natural radioactivity levels for radon gas in selected samples of some of the environmental elements in the Mosul city of (soil, plant and water) and making map of natural radioactivity for Mosul city using Geographic Information System technique. The concentration of (222Rn) and (238U) at twelve different regions in Mosul have been estimated using nuclear track detector (CR-39). The obtained results were entered to the computer in digital form, and it has been connected to data entered and stored by geographic coordinates with their spatial location using 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 were found 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 (17375193×105 Bq.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 the chambers and (17144468×105 Bq.m-3 ) radon concentration in the samples; in the water sample 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 radon concentration 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 the chambers (17562553×105 Bq.m-3 ) for radon concentration in the samples ; in the plant sample in Hai Al moalmen, (1796326: ppm) of uranium or (17448244×103 Bq.m-3 ) for radon in the air space of the chambers (17184498×105 Bq.m-3 ) for Radon concentration in the 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 the environment is not significant. But the important thing that were able to use the Geographic Information System program to draw the map of natural radiation in Mosul city as a mean for radioactivity monitoring periodically updated.
