Abstract
A study of the cavity displacement effect has been carried out using LiF rods of diameter 1 mm and length 6 mm. These LiF dosimeters were introduced into different sizes of cylindrical air cavities of length 30 mm each and diameters 30, 20, and 10 mm, respectively. A wide range of radiation energy was covered. A cavity displacement factor of 0.84 ± 0.08 expressing the distance of the effective measuring depth point from the center of the cavity as a fraction of the radius was obtained for X rays and γ rays. Plots showing the variation of the ratios of the cavity dose to the point cavity dose with cavity size and radiation energy are presented. A table giving the above-mentioned ratio in percentage for a 5 mm cavity diameter at a depth of 5 cm in a polystyrene phantom is also included. Further investigations at 39 MeV electron energy and for other radiation qualities are planned.
