Trend on the medical sources of radiation exposures to the population

We measured the patient dose using Thermoluminescent dosimeters (TLD) in individuals, who have been exposed to radiations during interventional radiological procedures. The overall measured doses ranged from 49.01-220.99 mSv for head 46.31-191.55 mSv for neck and shoulder was 7.83-155 mSv measured in patient undergoing cerebral angiography (n=50). The biological effect due to the radiation exposure is being quantified using CA, gamma H2AX and p53 Ser-15. The frequency of those changes will be correlated with the measured organ doses; the significance of the doses to that of biological effect received in the low dose radiation exposure will be discussed.
