Abstract

The invention provides a radioactive particle radiation dose measurement device.The measurement device comprises a tissue equivalent plate and particle through holes and dosimeter through holes which both penetrate through the tissue equivalent plate longitudinally.According to the radioactive particle radiation dose measurement device, the holes for containing radioactive particle and dosimeters are formed in the tissue equivalent plate and can fix the positions of the radioactive particles and the dosimeters, and therefore radiation dose measurement of the radioactive particles is conveniently conducted; radiation dose measurement is conducted by using the measurement device made of a tissue equivalent material, and therefore radiation values of the radioactive particles in a human body can be most truly and proximately reflected; the measurement devices of the different specifications can be arranged according to the distance among the particle through holes, the distance among the dosimeter through holes and the distance between the particle through holes and the dosimeter through holes, and then the radiation dose of single radioactive particle or more radioactive particles is measured.

Description

technical field

[0001] The invention relates to the technical field of radiation dose measurement, and more specifically, to a radiation dose measurement device for radioactive particles and a measurement method thereof. Background technique

[0002] Malignant tumors have always been a major disease that threatens human health. The use of radioactive particles for interstitial brachytherapy of tumors is a new technology developed in recent decades. The radioactive particle interstitial implantation technology has high tumor suppression efficiency and reasonable dose distribution. , It is convenient to cooperate with the operation to form a complementary advantage, so it has become a therapeutic method for treating tumors.

[0003] While treating tumors, in order to avoid damage to the tissues and organs around the tumor when radioactive seeds interstitial implantation technology is used to treat tumors, it is necessary to rationally place radioactive particles inside the tum...
