Method suitable for electron beam radiation processing operation identification

Abstract

The invention discloses a method suitable for electron beam radiation processing operation identification. The method comprises the steps of: (1) preparing 3 groups of equivalent-density simulation materials; (2) placing dose tablets in the simulation materials; (3) disposing a routine dosimeter in a specific place of the simulation material; ( 4 ) subjecting the 3 groups of simulation materials to electron beam irradiation; ( 5) reading the values of each group of the dose tablets and the routine dosimeter, and calculating related proportional coefficients; and (6 ) calculating the average value of dose distribution of all dose tablets on one layer of the 3 groups of simulation materials, and drawing a dose depth distribution map. The method of the invention solves the problems of poor uniformity of simulation materials, great uncertainty of depth dose distribution, large errors in the obtained proportional coefficients between the routine dosimeter and a maximum, minimum dose.

technical field

[0001] The invention relates to a method suitable for operation appraisal of electron beam radiation processing, which belongs to the technical field of radiation processing. Background technique

[0002] In the field of radiation processing, it is an essential process to use simulated materials of equivalent density for operation qualification and to measure the depth dose distribution of the material to be processed. The relevant parameters of the simulated material obtained according to the measurement can provide reliable information for radiation processing in accordance with.

[0003] Existing methods for operating identification of simulated materials and measuring depth distribution are relatively complicated and have low precision, which cannot provide a reliable basis for radiation processing technology. Moreover, these existing methods, in the next measurement, the maximum, The minimum dose distribution needs to be re-measured. Contents of the i...
