Abstract
In Sri Lanka chest radiography is the most commonly performed radiographic examination. Everyday-a very large number of populations is subjected to chest radiography to find lot of details about diseases as well as bone fractures. It is considered to be all ionizing radiation is harmful. This project deals with x rays. Therefore x radiation is also harmful. According to the beam strength of the x ray beam which is used for chest radiography a small amount of the dose can be deposited inside the patient's body and x rays can be scattered into many directions. This radiation including scatter radiation increases patient dose inside radiosensitive organs like gonads i.e. ovaries and testes. Since they carry genetic information generation by generation they are very important. Therefore my work is to determine the gonadal dose in patient’s undergoing chest radiography. To find the gonadal dose ionizing chamber dosimetry system was used and the radiation was measured in μGy. The sample size is hundred out of a huge population of people. At the end of the practical hundred readings were obtained. By analyzing the data which I have obtained from the practical it can be concluded that a very low dose of radiation varies from 0.2-16.0 μGy are incident on gonads during chest radiography. When it compared with the Entrance surface dose i.e.0.4 μGy this set of readings contains very low values. Therefore radiation effects on gonads are negligible.
