Measurement of environmental radioactivity for estimation of radiation Exposure from surface water in the Basrah Governorate


The dose rate of emitted gamma-rays from surface water taken from different locations in the Basra Governarte by using a TL- technique has been measured.The measurements were performed using lithium fluoride (liF)thermoluminescence dosimeters (TLD-200)at 32 stations ,the average dose rate measured in theBasrah environs was 3.01 µ rad/h. It is concluded that all the results obtained from this paper indicated that the inhabited area ling within the environmental monitoring stations are the areas in which the radiation is natural and that the dose rate that the human being exposed to, lie within the allowed limit.
