[0002] A kind of thermoluminescent detector to be detected is a wafer with a diameter of 4 mm and a thickness of 0.8 mm. The thermoluminescent detector can store the energy of ionizing radiation. Within a certain range, the stored energy has a linear relationship with the radiation dose. The stored energy can be measured by a specific thermoluminescent reader, and the read value can effectively reflect the radiation dose after correction. It is mainly used in the fields of personal dose monitoring of radiation workers, environmental radiation monitoring, radiation medicine dose measurement, and radiation protection dosimetry research, etc.

A plurality of vertically distributed positioning grooves 12 are provided on the outer walls on both sides of the support frame 1, and a carrying rod 7 is installed on the support frame 1 through the positioning grooves 12. A plurality of linearly distributed grooves 11 are provided on the outer wall of the front surface of the carrying rod 7. An outer cover 8 is sleeved on the front outer surface of the carrying rod 7. A protractor 9 is fixedly provided on the outer wall of one side of the support frame 1. A locking assembly 10 is provided at one end of the carrying rod 7 outside the support frame 1. Stop disks 13 are provided on the outer walls at both ends of the carrying rod 7. A support shaft installed inside the positioning groove 12 is provided on one side of the stop disk 13.

[0026] Specifically, in this embodiment, it includes a support frame 1. The support frame 1 is an integral U-shaped structure and serves as the basic support structure. A number of positioning grooves 12 are arranged vertically on the outer walls on both sides of the support frame 1. A load-carrying rod 7 is installed on the support frame 1 through the positioning grooves 12. A number of grooves 11 are arranged linearly on the outer wall of the front surface of the load-carrying rod 7. The grooves 11 are adapted to the specifications of the measurement pieces to be tested. The number of grooves 11 on each load-carrying rod 7 is at least ten, and the number of load-carrying rods 7 is at least eight, so that eight different angles can be measured at one time (for example, if the number of load-carrying rods 7 is set to eight and the number of grooves 11 on each load-carrying rod 7 is ten, then eighty measurement pieces can be measured at one time, and eight different angles can be obtained). The measurement pieces to be tested are placed one by one inside the grooves 11, thereby realizing the loading of the measurement pieces on the load-carrying rod 7. An outer cover 8 is sleeved on the outer part of the front surface of the load-carrying rod 7. The outer cover 8 ensures that the measurement pieces will not fall out of the grooves 11 on the load-carrying rod 7. A protractor 9 is fixedly arranged on the outer wall of one side of the support frame 1. When people adjust the angle of the load-carrying rod 7, the protractor 9 can be used as a reference for angle adjustment. A locking component 10 is arranged at one end of the load-carrying rod 7 outside the support frame 1. After the load-carrying rod 7 is installed on the support frame 1 and the angle of the load-carrying rod 7 is adjusted, the locking component 10 is used to lock the load-carrying rod 7 on the support frame 1. Stop disks 13 are arranged on the outer walls at both ends of the load-carrying rod 7. A support shaft installed inside the positioning groove 12 is arranged on one side of the stop disk 13. The load-carrying rod 7 can be installed inside the positioning groove 12 through the support shafts at both ends of the load-carrying rod 7, realizing the installation of the load-carrying rod 7 on the support frame 1. After the overall loading, the support frame is carried as a whole to one side of the radiation generating device, and the radiation generating device is used to perform radiation detection on the measurement pieces on the load-carrying rod 7. After 20 minutes of radiation, the measurement pieces are taken out for detection.

[0027] The thermoluminescent detector angular response irradiation device provided by the present utility model adopts a number of load-carrying rods 7 with adjustable angles and grooves 11, which can realize the loading of multiple measurement pieces, meet the radiation detection of measurement pieces under different angle conditions, and multiple different angle data can be obtained in one measurement.

[0028] As an embodiment provided by the present utility model, a lifting component is fixedly arranged at the center of the outer wall of the bottom of the support frame 1, and a base 6 is installed at the bottom end of the lifting component, ensuring the use stability of the support frame 1 by means of the base;

[0029] The lifting assembly includes a fixed cylinder 5 fixedly installed on the outer wall of the top of the base 6. A lifting rod 2 is slidably inserted into the top end of the fixed cylinder 5. A positioning ring 3 is provided at the top end of the fixed cylinder 5, and the lifting rod 2 is inserted into the positioning ring 3. A plurality of hand rods 4 are welded on the outer wall of the positioning ring 3 at equal intervals and distributed in a ring shape. When the operator needs to adjust the height of the support frame 1, the positioning ring 3 can be loosened first so that the lifting rod 2 can slide freely inside the fixed cylinder 5. After the height adjustment of the support frame is completed, the operator operates the positioning ring 3 in the reverse direction to make the lifting rod 2 and the fixed cylinder 5 relatively stationary.

[0030] In another embodiment provided by the present invention, the range of the protractor 9 is 0 - 180°. A pointer corresponding to the protractor 9 is provided on the outer wall of one end of the load-carrying rod 7. A pointer can be provided at one end of the load-carrying rod 7. When the load-carrying rod 7 rotates up and down, the pointer rotates synchronously. The angle of the load-carrying rod 7 can be determined by the reading of the pointer on the protractor 9. Since there are multiple load-carrying rods 7 arranged up and down, each load-carrying rod 7 can have an angle, so that multiple groups of radiation data at different angles can be measured under the radiation of the metering sheet at one time, making the detection of the metering sheet more efficient.

[0031] In still another embodiment provided by the present invention, the locking assembly 10 includes a threaded support rod 14 connected to the support shaft at one end of the load-carrying rod 7. A threaded sleeve 15 is externally threaded on the threaded support rod 14. A fixing ring 16 is fixedly installed on the outer wall of the threaded sleeve 15. A plurality of handles 17 are welded on the outer wall of the fixing ring 16. The operator can hold the handles 17 by hand to rotate the fixing ring 16 and the threaded sleeve 15 synchronously. The threaded connection between the threaded sleeve 15 and the threaded support rod 14 realizes the clamping of the support frame 1 between the threaded sleeve 15 and the stop disc 13, so as to realize the stable locking of the load-carrying rod 7 on the support frame 1. A handle 18 is fixedly provided on the outer wall of the back of the load-carrying rod 7 through bolts. The operator can hold the handle 18 by hand to take and place the load-carrying rod 7 and adjust the angle of the load-carrying rod 7.
