Description

Technical Field

[0001] This utility model belongs to the field of sanitary equipment, and specifically relates to a multifunctional thermoluminescence detector sieve box. Background Technology

[0002] When ionizing radiation irradiates a thermoluminescent detector, the detector can store the received ionizing radiation energy for a long time. When heated, it releases the stored radiation energy as light, and the intensity of the light is proportional to the radiation dose received. The radiation dose can be determined by detecting the intensity of the light. These detectors are typically made from powders of elements with good thermoluminescent properties, such as lithium fluoride, magnesium, copper, and phosphorus, mixed in a specific ratio and then pressed using a mold. Common shapes include round and square. Due to slight variations in content and purity between batches, the dispersion of detectors can vary. In practice, manufacturers generally use sampling methods to screen detectors to control dispersion, rather than testing all products individually. This causes problems for users: errors are introduced into the calculation of test results during instrument calibration, interlaboratory comparisons, and assessments by higher-level units, leading to deviations in calculation results and affecting the accuracy of the instrument and comparison results. Currently, the screening plates on the market are designed for manufacturers or calibration units with irradiation fields for convenient screening, without considering how users would screen detectors in their work. Utility Model Content

[0003] The present invention aims to provide a multifunctional thermoluminescence detector sieve box.

[0004] The objective of this invention is achieved as follows: it includes a first detector sieve plate, a second detector sieve plate, and a base. Both the first and second detector sieve plates are provided with lugs, and the base is provided with a slot. The lugs and the slot cooperate to form a detachable structure. The first detector sieve plate is provided with 20 transverse and 30 longitudinal detector slots, for a total of 600 slots. The second detector sieve plate is provided with 7 groups of slots, each group having 48 slots. The detector slots are through-hole structures.

[0005] Compared with the prior art, the present invention has the following advantages and effects: This utility model consists of two sieve plates (white acrylic plates) with detector slots, which are fastened onto a base (aluminum plate with a black film) with slots, forming a detachable sieve box. One sieve box has 20 horizontal and 30 vertical detector slots, totaling 600 slots. The slots are marked with blue lines (84 slots), red lines (100 slots), and black lines (600 slots) on the plate. Depending on the application, it can screen conventional comparison sieves, calibration sieves, and conventional test sieves with the aid of external irradiation, eliminating abnormal detectors. The other sieve box consists of seven groups of slots, each with 48 slots. Each group is arranged in the manner of energy identification dosimeters, which have a high market share. The positions and reading order are marked to facilitate the calculation of reading results and to accurately screen detectors during the process, eliminating abnormal detectors. Both sides can achieve screening functions for four different applications. This sieve box uses an aluminum plate as the base for the detector. Utilizing aluminum's thermal conductivity, it quickly cools the detector, protecting it. The black-coated base makes the white detector easily visible. This sieve box fixes each detector in a slot and is suitable for screening square and round detectors. It is suitable for screening detectors in the absence of an irradiation device, relying on natural radiation or external verification and comparison of irradiation values. It is also suitable for screening detectors in the presence of an irradiator. Attached Figure Description

[0008] The present invention will be further described below with reference to the accompanying drawings, but this is not intended to limit the invention in any way. Any modifications or substitutions made based on the teachings of the present invention shall fall within the protection scope of the present invention.

[0009] As shown in the attached figure, a multifunctional thermoluminescent detector sieve box includes a first detector sieve plate, a second detector sieve plate, and a base. Both the first and second detector sieve plates are provided with lugs, and the base is provided with a slot. The lugs and the slot cooperate to form a detachable structure.

[0010] The first and second detector sieve plates are made of white acrylic sheets, and the base is made of aluminum sheet coated with a black film.

[0011] The first detector sieve plate has 20 horizontal and 30 vertical detector slots, for a total of 600 detector slots; the second detector sieve plate has 7 groups of detector slots, with 48 detector slots in each group. Example 1

[0012] This detachable screening box consists of two plastic plates with detector slots attached to an aluminum plate with slots. One box has 20 horizontal and 30 vertical detector slots, totaling 600 slots. The slots are marked with blue lines (84 slots), red lines (100 slots), and black lines (600 slots), allowing for the screening of standard comparison, calibration, and testing plates with external illumination, eliminating abnormal detectors. The other box consists of seven groups of 48 slots each, arranged like energy-discriminatory dosimeters, with marked positions for easy result calculation. This allows for precise detector screening and elimination of abnormal detectors. Both boxes offer screening functionality for four different applications. The aluminum plate serves as the base for the detectors, utilizing aluminum's thermal conductivity for rapid cooling and detector protection. Each detector is fixed in its slot, making this box suitable for screening square and round detectors. This sieve box is suitable for screening detectors in the absence of an irradiation device, relying on natural radiation or external verification and comparison of irradiation values. It is also suitable for screening detectors in the presence of an irradiator.

[0013] The working principle and process of this utility model:

[0014] Depending on the purpose of irradiation (e.g., irradiating a test plate), one of the sieve plates is selected as the cover plate for the aluminum plate. The irradiated detectors are then read using a thermoluminescent dosimeter, and placed sequentially in the detector slots. The detector dispersion (also known as the "coefficient of variation," which is the ratio of the standard deviation to the mean) is calculated based on the readings. Detectors with dispersion values ​​higher than the target (e.g., 1%) are discarded, and the remaining detectors can be used for the next comparison. The discarded detectors can be used for routine testing or directly recycled based on their calculated dispersion.

[0015] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
