Investigation of Natural Occurring Radioactive Material Activity Level in Falluja-Anbar (Iraq)

Radiation may be defined as the energy in form of electromagnetic waves or particles that pass through space and even heavy dense materials. The radioactivity is a continuously decreasing quantity which function half-life responsible radionuclides. natural sources radiation came from terrestrial radionuclides are widely distributed earth's crust. Field radiological surveys were conducted by GR-460 mobile detection system, only system Iraq region. This dedicated to scanning process for large areas less time. attached GPS satellite positioning device so measurement points coupled with spatial coordinates radiometric area. In this study, concentration naturally occurring radioactive materials had been determined experimentally AL-Falluja / Anbar Governorate- (66) km2 using portable gamma spectrometer system. results showed high level uranium (238U) was 8.1 ppm industrial area, low 0.1 most districts. Thorium (232Th) 17.5 than neighborhoods within Iraq's background.
