THE DETERMINATION OF RADON GAS CONCENETRATION DISTRIBUTED NORTH OF BAGHDAD GOVERNORATE: SPATIAL ANALYSIS BY APPLYING REMOTE SENSING (RS) AND GEOGRAPHIC INFORMATION SYSTEM (GIS) TECHNIQUESFouad K. Mashee Al Ramahi, Muaid Jassim Rasheed and Mazin Shakir Jasim
In this research, concentration of radon gas has been measured in the polluted environment inside in Baghdad Conservation surface soil sample, this was done using the RAD7 mobile detector. This measurement has been made for selected areas of the middle and northern Baghdad governorate. The work consists of three parts, the first part includes calculating the latitude and longitude of each location point of measurement the study area using the Global Positioning System (GPS). The second part of which includes determination of Rn222 gas concentrations in surface soil samples. The finding highest average in the northeastern part of Baghdad was found in the Shaab Subdistrict area (175.33 Â± 5.61Bq/m3), because, that is to near from the oil well locations. Also in the northwest part of Baghdad, the highest average concentration of radon was found in Altaji, Equal to (179.16 Â± 5 85 Bq/m3), because, complex fertilizer the arable land such as phosphate. The third part includes applied standard deviation (elliptical) to determine the radon gas spread regions and the applied the techniques of interpolation using the radon data available in the known sites to estimate the radon data for the non-measured area, which will help to develop an effective plan to reduce the concentration of radon in the study area.
