Problems solved by technology

[0005] Since the radiation dose required for the screening of thermoluminescent dose components is generally relatively small, and each batch of new dose components needs to be screened, it is not suitable to use the first two types of standard radiation fields from all aspects. For the convenience of use and It is easy to operate, and it is urgent to develop an intelligent thermoluminescence irradiator

Embodiment Construction

[0034] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] A thermoluminescent irradiator, with a built-in standard radiation field used to calibrate the dose, quantitatively irradiates the annealed thermoluminescent element, including a main body 1, a disk 2, a sample disk 3, and a radiation source 4. Stepper motor 5, upper cover 6, display screen 7, keyboard 8;

[0036] The main body 1 is the overall shape structure of the thermoluminescent irradiator;

[0037] The disk 2 is a metal disk that rotates at a uniform speed controlled by a stepping motor 5, and there are 37 sample disks 3 evenly distributed at equal intervals on the disk 2, which are used to place the thermoluminescent dose elements to be irradiated;

[0038] The stepper motor 5 drives the disc 2 to rotate according to the preset speed and the calculated number of revolutions during irradiation to reali...

Abstract

The invention belongs to the technical field of radiation equipment auxiliary instruments, belongs to a part of a thermoluminescence measurement system, and in particular relates to a thermoluminescence irradiator. The thermoluminescence irradiator of the present invention is a key instrument matched with a thermoluminescence dosimeter, comprising a main body 1, a disc 2, a sample tray 3, an irradiation source 4, a stepping motor 5, an upper cover 6, a display screen 7, The keyboard 8 has a thermoluminescent readout device for irradiating the annealed thermoluminescent element for screening and calibration of the thermoluminescent element. When in use, set parameters according to the required radiation dose, and the instrument can place multiple thermoluminescence dose components at a time.

Description

technical field [0001] The invention belongs to the technical field of radiation equipment auxiliary instruments, belongs to a part of a thermoluminescence measurement system, and in particular relates to a thermoluminescence irradiator. Background technique [0002] The thermoluminescence irradiator is matched with the thermoluminescence reader, thermoluminescence annealing furnace and thermoluminescence detector to form a thermoluminescence measurement system. The thermoluminescence irradiator has the function of irradiating the annealed thermoluminescence detector (that is, the dose element) in order to screen the thermoluminescence detector and calibrate the thermoluminescence dosimeter, provide a relatively standard radiation field, and to the calibration dose. At the same time, it can also be used for other small samples (such as the irradiation of quartz ore powder samples in geological and mining systems) for low-dose irradiation. [0003] There are many types of t...
