Embodiment 1

[0032] The constant temperature phantom device used for the study of the dosimetry performance of dosimeters on the electron beam. The electron beam energy is 10MeV. Temperature control system connection.

[0033] The structure of the irradiation phantom is as figure 1 As shown, it mainly includes the main body of the radiation phantom in the middle part and the water inlet pipe 5 and the water outlet pipe 9 on both sides; the material of the main body of the radiation phantom is aluminum, the shape is a hollow cuboid shape, and the upper panel is mainly welded together by sealing 6. The lower panel 8 and the middle frame 3 are composed, wherein the upper panel 6 or the lower panel 8 can be used as the irradiation surface, and one side of the middle frame 3 is internally welded with a dosimeter casing 7 for placing the dosimeter accommodating column 2 And the thermometer casing 1 for placing the thermometer, the dosimeter containing column 2 is used for placing multiple grou...

Embodiment 2

[0039] The difference from Example 1 is that the dosimetry response study of the dosimeter was carried out at an electron beam energy of 12 MeV; the distance between the radial center of the dosimeter sleeve and the irradiation surface was 34 mm. The dosimeter shall be irradiated with electron beam after the temperature balance in the constant temperature phantom device for 40 minutes in advance.

Abstract

The invention belongs to the technical field of radiation dosage and discloses a constant temperature die body device for conducting dosimeter performance study on an electron beam.The applicable electron beam energy range of the device is 10 MeV or above; the device comprises an irradiation die body, a water circulation system and a temperature control system, and the water circulation system is connected with the irradiation die body and the temperature control system.By means of the device, dosimeter dosimetry performance research, particularly temperature response research can be conducted on electron beam flows led out of an electron linear accelerator so that dosimetric parameters such as adsorbed dose can be corrected.

Description

technical field [0001] The invention belongs to the technical field of radiation dose, and in particular relates to a constant temperature phantom device for conducting research on the dosimetry performance of a dosimeter on an electron beam. Background technique [0002] With the development of radiation processing technology, more and more 60 Coγirradiation devices and electron accelerators have been established. How to accurately and reliably measure the absorbed dose of irradiated products, monitor and control the process parameters of the irradiation devices, and improve the quality of irradiation has become a major issue for metrological supervision departments and irradiation units. issues of common concern. [0003] currently used for 60 Dosimeters for Coγ-ray and electron beam dose supervision and measurement include liquid chemical dosimeters, radiochromic film dosimeters, CTA film dosimeters, alanine dosimeters, etc. The dose response of these different types of...
