Description

Technical Field

[0001] The invention relates to the technical field of radiation dose measurement, in particular to a thermoluminescent dose device whose energy response is positively correlated with ray energy. Background Art

[0002] Thermoluminescent dosimeter is a commonly used instrument for monitoring personal radiation dose and environmental radiation dose. It has the advantages of small size, high sensitivity, wide range, and a wide range of measurement objects. It responds to X, γ, α, β, neutrons, protons, and heavy charged particles. It is widely used in radiation protection, radiation medicine, radiation biology, radiation environment monitoring and other fields. Common thermoluminescent materials include LiF, CaSO 4 wait.

[0003] The principle of thermoluminescence is: when the thermoluminescent material is irradiated by rays, some electrons are excited, and the excited electrons move in the lattice and are captured by traps in the lattice. When the thermoluminescent material is heated, the captured electrons gain energy and are re-excited to the conduction band, where they recombine with the luminescence center and produce luminescence. This phenomenon is called thermoluminescence. The total number of photons released by heating is proportional to the electrons released from the traps, and the number of electrons is proportional to the radiation energy absorbed by the thermoluminescent material. Therefore, the radiation deposition energy can be evaluated by measuring the total number of photons, and the corresponding radiation dose can be calculated.

[0004] Ideally, the energy response curve of a thermoluminescent dosimeter is in a monotonically increasing relationship with the energy of the incident X / γ rays, that is, the greater the energy of the incident X / γ rays, the more photons the thermoluminescent dosimeter produces, and the higher the calculated radiation dose. At present, most thermoluminescent dosimeters have certain defects in the response in the energy region of 20-100 keV, and there is a problem of excessive energy response, which affects the accuracy of dose measurement. If the energy response in this energy region is reduced simply by shielding the 20-100 keV X / γ rays incident on the thermoluminescent dosimeter, then while shielding the 20-100 keV X / γ rays, the X / γ rays with energy less than 20 keV will be shielded and attenuated to a greater extent, resulting in a significant decrease in the energy response of the thermoluminescent dosimeter in the low-energy region, which seriously affects the lower limit of energy detection of the thermoluminescent dosimeter.

[0005] Therefore, there is an urgent need for a thermoluminescent dosage device whose energy response is positively correlated with the radiation energy and can maintain the energy response in the low energy region. Summary of the invention

[0033] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0034] Energy response is a key technical indicator of the thermoluminescent dosimeter. The relative energy response of the LiF thermoluminescent dosimeter can be calculated by the following formula:

[0035]

[0036] Where R(θ,E) is the relative energy response, K(θ,E) LiF K(0,Cs) is the kerma of X / γ-rays with energy E incident on the LiF thermoluminescent film at an angle θ. Air for 137 The energy of the Cs radiation source is the deposition energy of 662keV gamma rays in the air, K(0,E) Air K(0,Cs) is the kerma of X / γ rays of energy E in air. LiF for 137 The energy of the Cs radiation source is 662keV gamma rays incident vertically on the LiF thermoluminescent film. The kerma, h(0,Cs) is 137 The conversion coefficient of kerma to personal dose equivalent when the energy of Cs radiation source is 662keV gamma ray incident vertically, h(θ,E) is the conversion coefficient of kerma to personal dose equivalent when X / γ ray of energy E is incident at angle θ, η(E) is the efficiency of X / γ ray of energy E causing LiF thermoluminescent dose device to emit light. LiF and K(0,Cs) LiF Except for this, the other parameters in the formula are values ​​that are independent of the structure of the thermoluminescent dosage device.

[0037] In order to make the energy response curve of the thermoluminescent dose device monotonically increase with the incident X / γ ray energy, that is, the greater the incident X / γ ray energy, the more photons the thermoluminescent dose device generates, and the higher the calculated radiation dose. The thermoluminescent dose device of the present invention, whose energy response is positively correlated with the ray energy, achieves the purpose of increasing the energy deposition of X / γ rays with energy <20keV on the thermoluminescent film, improving the energy response of the thermoluminescent dose device in the low energy region, maintaining the detection lower limit of the thermoluminescent dose device in the low energy region, and making the energy response curve of the thermoluminescent dose device positively correlated with the incident X / γ ray energy.

[0038] Figure 1 and Figure 2 The structure of the thermoluminescent dose device whose energy response is positively correlated with the radiation energy is described in general; Figure 1 A schematic diagram of the structure of a thermoluminescent dosage device provided by an embodiment of the present invention, the energy response of which is positively correlated with the radiation energy; Figure 2 for Figure 1 Side view of.

[0039] like Figure 1 and Figure 2 As shown, the thermoluminescent dose device with energy response positively correlated with radiation energy comprises a dose kit 3 and a deep dose module 1 and a superficial dose module 2 arranged in the dose kit 3; the dose kit 3 is irradiated with an X / γ radiation field in a direction from the front side wall to the rear side wall; the deep dose module 1 is used to measure the deep radiation dose, and comprises a deep energy compensation filter 102, a deep thermoluminescent film 101 and a deep anti-scattering film 104 arranged in sequence according to the order of receiving the X / γ radiation field irradiation; wherein a deep filter through hole 103 is arranged at the center of the deep energy compensation filter 102; the superficial dose module 2 is used to measure the deep radiation dose. For measuring superficial radiation dose, it includes a superficial energy compensation filter 202, a superficial thermoluminescent film 201 and a superficial anti-scattering film 204 which are arranged in sequence according to the order of receiving X / γ radiation field irradiation; wherein a superficial filter through hole 203 is arranged at the center of the superficial energy compensation filter 202; the superficial energy compensation filter 202 of the superficial dose module 2 is closely arranged on the front side wall, and the deep anti-scattering film 104 of the deep dose module 1 is closely arranged on the rear side wall; wherein the circular end face of the superficial energy compensation filter is in contact with the inner wall of the front side wall, and the circular end face of the deep anti-scattering film 104 is in contact with the inner wall of the rear side wall.

[0040] That is to say, two thermoluminescent dose modules are placed in the dosimeter box. One is called the deep dose module, which is used to measure the deep radiation dose. For strong penetrating radiation, the absorbed dose at a depth of 10 mm from the body surface when the radiation is vertically incident is generally examined, and is represented by Hp (10, 0°); the other is called the superficial dose module, which is used to measure the superficial radiation dose. For weak penetrating radiation, the absorbed dose at a depth of 0.07 mm from the body surface when the radiation is vertically incident is generally examined, and is represented by Hp (0.07, 0°). Each thermoluminescent dose module is composed of a thermoluminescent sheet, an energy compensation filter, a filter through hole and an anti-scattering sheet, wherein the thermoluminescent sheet is the core device that receives radiation and generates photons, and the energy compensation filter is used to filter X / γ rays and reduce the X / γ rays with energy between 20-100keV from entering the thermoluminescent sheet. However, since the energy compensation filter has a stronger shielding effect on X / γ rays with energy <20keV, a through hole is opened in the energy compensation filter and an anti-scattering sheet is added behind the thermoluminescent sheet to increase the X / γ rays with energy <20keV entering the thermoluminescent sheet. Among them, the function of opening a through hole in the energy compensation filter is to increase the probability of X / γ rays with energy <20keV generated by scattering with the environment and the materials of the thermoluminescent dose device entering the thermoluminescent sheet, and the function of the anti-scattering sheet is to reflect some of the X / γ rays that pass through the thermoluminescent sheet and increase the number of X / γ rays with energy <20keV entering the thermoluminescent sheet.

The superficial dose module 2 is composed of a superficial thermoluminescent sheet 201, a superficial energy compensation filter 202, a superficial filter through hole 203 and a superficial anti-scattering sheet 204.

[0048] It should be noted that the dimensions of the various structures of the dosimeter box 3, the deep dose module 1 and the superficial dose module 2 are not unique, and they can achieve the purpose of accurately measuring the radiation dose, and are not specifically limited again. However, during the experiment, the dimensions of each structure were limited to the following values ​​through simulation calculations, achieving the best effect of improving the radiation dose measurement accuracy of the deep dose module 1 and the superficial dose module 2.

[0049] The dosimeter box 3 is 3 cm long, 2 cm wide, and 0.7 cm thick, and is made of polytetrafluoroethylene (PTFE). The deep dose module 1 and the superficial dose module 2 are cylindrical, with a diameter of 4.5 mm and a height of 2.45 mm. The thickness direction of the dosimeter box 3 is consistent with the height direction of the deep dose module 1 and the superficial dose module 2; the length direction of the dosimeter box 3 is consistent with the diameter direction of the deep dose module 1 and the superficial dose module 2. The deep dose module is a cylinder formed by the coaxial arrangement of the deep energy compensation filter, the deep thermoluminescent film and the deep anti-scattering film; the axis where the center of the deep dose module is located is located 1 cm downward from the upper edge of the rear side wall along the midline; the superficial dose module is a cylinder formed by the coaxial arrangement of the centers of the superficial energy compensation filter, the superficial thermoluminescent film and the superficial anti-scattering film; the axis where the center of the superficial dose module is located is located 1 cm upward from the lower edge of the front side wall along the midline; that is, the center of the deep dose module 1 is located in the middle position of the back side 1 cm downward from the upper edge of the dose meter box 3, the center of the superficial dose module 2 is located in the middle position of the front side 1 cm upward from the lower edge of the dose meter box 3, the upper bottom surface of the superficial energy compensation filter 202 is flush with the front side of the dose meter box 3, and the lower bottom surface of the deep anti-scattering film 104 is flush with the back side of the dose meter box 3.

[0050] The deep energy compensation filter 102 is a circular cylinder with an outer diameter of 4.5 mm, an inner diameter of 1.6 mm, and a thickness of 0.6 mm, and is made of 304 stainless steel. The superficial energy compensation filter 202 is a circular cylinder with an outer diameter of 4.5 mm, an inner diameter of 1.0 mm, and a thickness of 0.6 mm, and is made of copper. The deep filter through hole 103 is a cylinder with a diameter of 1.6 mm and a thickness of 0.6 mm, and the superficial filter through hole 203 is a cylinder with a diameter of 1.0 mm and a thickness of 0.6 mm. The deep thermoluminescent film 101 and the superficial thermoluminescent film 201 are both cylinders with a diameter of 4.5 mm and a thickness of 0.8 mm, and are made of LiF. The deep anti-scattering film 104 and the superficial anti-scattering film 204 are both cylinders with a diameter of 4.5 mm and a thickness of 1.05 mm, and are made of metal beryllium.

[0051] Thermoluminescent dose device whose energy response is positively correlated with the energy of radiation is used to measure radiation dose, and the X / γ radiation field is irradiated to the dose reagent box 3 in the direction from the front side wall to the rear side wall; the superficial dose module 2 is irradiated first, and the deep dose module 1 is irradiated later. The energy compensation filter filters the X / γ rays, reducing the X / γ rays with energy of 20-100keV entering the thermoluminescent sheet; the through hole opened on the energy compensation filter increases the probability of X / γ rays with energy <20keV generated by scattering with the environment and the thermoluminescent dose device material entering the thermoluminescent sheet; the anti-scattering sheet added behind the thermoluminescent sheet reflects part of the X / γ rays that pass through the thermoluminescent sheet, increasing the number of X / γ rays with energy <20keV entering the thermoluminescent sheet; and thus the energy response curve of the thermoluminescent dose device that is positively correlated with the energy of the incident X / γ rays is obtained.

[0052] The energy response curve obtained by using the thermoluminescent dose device of this embodiment, whose energy response is positively correlated with the radiation energy, is as follows: Figure 4 shown.

[0053] By comparing Figure 3 and Figure 4 It can be seen that the energy response of the thermoluminescent dose device in Example 2, whose energy response is positively correlated with the ray energy, is monotonically increasing with the energy of the incident X / γ ray. The energy deposition of 10 keV X / γ ray on the thermoluminescent film is reduced to 7.7% of the original value, and the corresponding detection threshold is increased by about 3.6 times of the original value.

[0054] The thermoluminescent dosimeter of the present invention has an energy response positively correlated with the energy of the ray. By arranging an energy compensation filter in front of the thermoluminescent sheet, the energy deposition of X / γ rays with an energy range of 20-100 keV is reduced, and the energy response in the energy region is reduced, thereby solving the problem that most existing thermoluminescent dosimeters have an overly high instrument response in the energy range of 20-100 keV. The energy response curve of the thermoluminescent dosimeter is improved, so that the energy response of the thermoluminescent dosimeter is in a monotonically increasing relationship with the energy of the incident X / γ ray, thereby achieving the technical effect of improving the measurement accuracy of the thermoluminescent dosimeter. By opening a hole in the energy compensation filter and arranging an anti-scattering sheet behind the thermoluminescent sheet, the energy deposition of X / γ rays with an energy less than 20 keV on the thermoluminescent sheet is increased, the energy response of the thermoluminescent dosimeter in the low energy region is improved, and while maintaining the detection lower limit of the thermoluminescent dosimeter in the low energy region, the technical effect of making the energy response curve of the thermoluminescent dosimeter positively correlated with the energy of the incident X / γ ray is achieved.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
