Description

Technical Field

[0001] The present invention relates to the technical field of radiation measurement, and in particular, to a full-automatic radiation dose measurement device and method. Background Art

[0002] Radiation is rays, and the rays can kill not only proliferating and active cells, but also proliferating and inactive cells. Proliferating and active cells include intestinal mucosal cells, so nausea and vomiting will occur. It can also kill hair follicle cells, causing hair loss. It can also kill white blood cells, causing a decrease in white blood cells and bone marrow suppression. There are many harms of radiation. Killing nerve cells will lead to memory decline and dementia, and there is also paraplegia. If a person is in an environment with a radiation dose of 100-500 mSv for a long time, the number of white blood cells in the human blood will decrease. If the radiation dose is in the range of 1000-2000 mSv, symptoms such as fatigue, vomiting, and loss of appetite may occur. If the radiation dose is 2000-4000 mSv, the number of red blood cells and white blood cells in the human blood will decrease significantly, and internal bleeding and other situations may occur. When the radiation dose > 4000 mSv, there may be a life-threatening situation.

[0003] Since radiation has such great harm to the human body, especially for workers who work in a radiation environment for a long time (such as staff in the imaging department, nuclear medicine department, radiotherapy department, flight attendants, nuclear power plant workers, etc.), it is very necessary to quickly measure the cumulative radiation dose suffered by the above-mentioned personnel within a certain period of time. At present, the main methods for measuring radiation dose are still mainly individual measurement or semi-batch measurement, and it is still difficult to form batch continuous measurement. This measurement efficiency is difficult to meet the current requirements for radiation dose measurement. The existing semi-batch measurement technology mainly refers to manually scanning label information, recording the information of the detected object, then putting the samples into the measurement device in sequence, and then measuring them one by one in sequence. The main disadvantage of the semi-batch measurement technology is that once the order of putting the samples is disordered, it will lead to the mismatch between the information of the detected object and the radiation dose information, further resulting in incorrect measurement results, and the number of samples measured at one time by the semi-batch measurement technology cannot exceed 60.

[0004] Therefore, in order to quickly and accurately measure the cumulative radiation dose and match it correctly with the information of the detected object, it is urgent to find a full-automatic radiation dose measurement device and method that can measure the radiation dose in batches, so as to avoid the problem that the order of the samples to be measured is disrupted, resulting in the mismatch between the measurement result and the information of the detected object. Summary of the Invention

[0005] The present invention provides a fully automatic radiation dose measurement device and method. The fully automatic radiation dose measurement device effectively combines the automatic sample circulation technology with the automatic identification technology and the automatic measurement technology to solve the technical problems in the prior art that it is difficult to batch measure a large number of radiation dose samples, the order of a large number of radiation dose samples is easily disrupted, resulting in easy matching errors between the information of the detected object and the dose information, and thus inaccurate measurement results.

[0006] To achieve the above technical objectives, the technical solution of the present invention is as follows:

The fixed distance here may be the distance of one sample placement assembly, that is, the distance between the centerlines of two adjacent sample placement assemblies. By rotating a fixed distance each time, it is ensured that the sample placement assemblies can be moved into the placement unit of the sample placement assembly to be measured one by one.

[0016] A specific implementation may be that the sample replacement unit (23) can be a push-pull assembly, an elastic assembly, a grasping assembly, or a conveyor belt assembly.

[0023] Step 2: After the sensor component senses that the sample placement component has been moved into the placement unit of the sample to be measured placement component, the sensed information is transmitted to the main control unit;

[0024] Step 3: The main control unit controls the sample replacement unit to transfer one sample in the sample placement component to the measurement chamber. After the sensor component senses that the sample to be measured has been stably placed, the stable placement information is transmitted to the main control unit;

[0025] Step 4: The main control unit starts the automatic recognition module. The automatic recognition module recognizes the information of the object to be detected recorded in the information label of the sample to be measured, and transmits the information of the object to be detected to the main control unit;

[0026] Step 5: The main control unit starts the automatic measurement module. The radiation dose information acquisition unit acquires the radiation dose information of the sample to be measured, and transmits the acquired radiation dose information to the main control unit. The main control unit performs corresponding matching between the radiation dose information and the information of the object to be detected;

[0027] Step 6: When reaching the measurement end point, the sample replacement unit moves the sample to be measured out to the sample collection bag. At the same time, it is judged whether there is still a sample in the sample placement component in the placement unit of the sample to be measured placement component.
