摘要
Both Arc GIS 9.2 and ERDAS 9.1 software were used to analyze the concentrations in radiation exposure of marshlands in southern Iraq during June 2009 and January 2010. It was measured radiation exposure rates above the soil and water surface, and also measured radioactivity in the environmental models （soil, plants, sediment and water） for all the selected sites of the study area. Furthermore, it has＂ been measuring the level of radioactive contamination concentration of the isotope Bi-214 and Ac-228 and K-40 as well as peer-Cs-137-resulting from the operations of nuclear fission and measured the background radiation compared with other regions. Environmental samples （soil-water-plant-deposits） were taken and measuring the concentration ratio of radioisotopes in using the system account gentle rays Kama multi-channel and using the counter--Nal-tinged element--thallium--Type-WIZARD-1470 as well as a LB 1200. The results showed the regions of the marshes of radioactive contamination now.
