A MEASUREMENT DEVICE OF RADIATION DISTRIBUTION USING DOSIMETRY FILM AND A MEASURING METHOD THEREOF

摘要

According to the present invention, a dose distribution measurement device of incident radiation using a film to measure radiation comprises: a prism member disposed on a traveling path of incident radiation, has the shape of a right triangle on a cut surface cut to the traveling path of the incident radiation, and is extended in a direction perpendicular to the cut surface; a film for reference beam detection disposed to be close to the front surface of the prism member, and detects the dosage distribution of the incident radiation; and a film for through-beam detection close to the rear surface of the prism member to detect the dosage distribution of the radiation after the radiation passes through the film for reference beam detection and the prism member.
