| Summary: | This research project attempts to find out whether the radiation doses at points of identical perpendicular distance from vertical axis of a diagnostic x-ray tube are similar or different. It consists of two parts. A Geiger Muller tube was used as a detector to measure dosages at several points along the x-axis and y-axis of a plane 100 cm below the x-ray tube. The Geiger Muller tube was then replaced by a few thermoluminescence dosimeters. These dosimeters were hung in a circular contour surrounding the x-ray tube. Measurements were taken for different plane levels and radius. Analysis from the obtained readings has shown that the doses are actually different, even at equal right angle lengths measured from vertical axis of the x-ray source. Factors contributing to the above result are listed in the final chapter of this report. |
