Embodiment 1

[0045] like image 3 , 4 , 5 shown.

[0046] A method for measuring the effective range of electron beam radiation, comprising the following steps:

[0047] First, cut the plate glass into a long block structure as the dosimeter basic unit of the glass dose indicator D, and arrange the dosimeter basic unit on the surface of cardboard, plastic, wood or cloth and fix it to form a glass dosimeter. Dose indicator D, the dosimeter basic units can be closely connected or arranged at intervals to form a glass dose indicator matrix arrangement {m; n}, where m is the number of dosimeter basic units in the length direction, m≥3; n is the number of dosimeter basic units in the width direction, n≥1, where each dosimeter basic unit is recorded as D (m，n) , the matrix arrangement of glass dose indicators is called "dose indicator belt" and is denoted as D (m×n) ;

[0048] Secondly, place an incident dose indicator tape D for incident reference on the upper surface of the irradiated pro...

Embodiment 2

[0097] like Figure 4 shown.

[0098] A belt-shaped electronic radiation dose indicator, which is characterized in that it is composed of a glass sheet 1 as the basic unit of the dosimeter and a flexible fixing belt 2, and each flexible fixing belt 2 is fixed with at least one row of no less than three pieces of glass slice 1. The glass sheets 1 can be fixed on the flexible fixing belt 2 at intervals or adjacent to each other, and the rows can be arranged at intervals or adjacent to each other. The glass sheet 1 should adopt colorless transparent glass or light background color transparent glass. The glass sheet 1 can be ordinary glass plates such as flat glass, glass bottles and jars, and utensils. Flexible fixing band 2 can be attachable things such as cardboard, plastics, plank, cloth, as Figure 4 shown.

Abstract

The invention relates to a determination method for the effective range of electronic beam radiation and a banded measuring meter; the determination method is characterized by comprising the following steps of: firstly manufacturing glass dosage indicating meter bands arrayed in a (m, n) matrix manner by using common plate glass as a material, slantwise inserting the glass dosage indicating meter bands into a product box to be irradiated for carrying out irradiation, then taking out two rows of adjacent dosage meters with close color differences in the dosage indicating meter bands for superposition, and carrying out color comparison between the two rows of adjacent dosage meters and reference dosage meters which are arranged on the top surface of the product box and are used for irradiation, and finding out the positions of the dosage meters with equal colors, wherein the distances between the positions to the top surface of an irradiation box are the effective range of the electronic beam radiation, and the double-distance is the best irradiation thickness of the product. The determination method has the advantages of strong generality, low cost and convenience and rapidness in operation.

Description

technical field [0001] The invention relates to an electron beam irradiation dosimetry technology, in particular to a method for measuring the optimum depth of product irradiation and its dosimeter, in particular to a method for measuring the effective range of electron beam radiation and a strip dosimeter. Background technique [0002] As we all know, electron beam radiation processing has the advantages of large radiation power, high dose rate, fast processing speed and low cost, and has developed rapidly at home and abroad in recent years. According to incomplete statistics, the number of electron accelerators in my country has increased to more than 200, and it is also showing a rapid growth trend. With the rapid development of the electron beam radiation processing industry, there is an urgent need for a dose measurement system suitable for electron beam dose measurement. At present, the methods for quantitative determination of electron beam radiation dose are: calor...
