Description
Technical Field
The utility model discloses the radiation hygiene detection techniqueFIELDThe utility model relates to a device for distributing and recovering dosimeters, in particular to a personal dosimeter distribution and recovery management system.
Background
Occupational external exposure personal dose monitoring provides a basis for evaluating the dose level of a radiology worker and researching the radiation health protection measures of a medical institution. After the national health system has issued GB5298-85 personal dose monitoring and managing regulations for radiology workers in 14.10.1985, the national health system carries out the personal dose monitoring work of the radiology workers one after another. In 1989, 1024-day promulgated "radioactive isotope and ray device radiation protection regulations" (State Council No. 44 directive), and the smooth development of the personal dose monitoring work of the radiological workers is guaranteed in the policy and regulation level. In 1997 in 1988, the Ministry of health issued "health management regulations of radiology workers" in the beginning and end of the year, aiming at providing management contents and international connection for radiology worker training, personal dose monitoring management, occupational health management and the like. The 2001 work of monitoring the personal dosage is incorporated into the disease prevention and treatment method of the people's republic of China. Occupational external irradiation personal dose monitoring (GBZ128) regulates the implementation step technology of personal dose monitoring work, and requires that a radiological worker should wear a personal dose meter to monitor radiation hazard dose, and the monitoring period is 1-3 months. In summary, personal dose monitoring is not only an obligation of the radiology work unit and the radiology staff, but also a legal task.
According to the requirements of national laws and regulations, personal protective articles equipped in different categories of radiological and professional posts are different, wherein a lead rubber apron is equipped at the operation posts of equipment side operation such as X-ray equipment for radiology and diagnosis, equipment side operation such as photography and orthopedics reduction, interventional radiology operation and the like, and a lead rubber cap, a lead rubber neck sleeve, a lead rubber glove and lead protective glasses are also optionally equipped. According to the wearing requirements of occupational external irradiation personal dose monitoring (GBZ 128-2019), intervention irradiation personnel, nuclear medicine radiopharmaceutical subpackaging, injection and other works with uneven whole-body irradiation are carried out, a personal dosimeter is worn at the position of a collar corresponding to the outside of a clavicle of a lead apron, and another personal dosimeter is worn on the trunk inside the lead apron. The local dosimeter such as a head band dosimeter, a wrist dosimeter, a ring dosimeter and the like is worn at the part which can be irradiated. As the work types of one radioactive worker are different, more than or equal to 1 dosimeter is required to be worn. When personal dose monitoring is carried out, a monitoring mechanism often sends dosimeters with different colors to the radiation staff, and the dosimeters are required to be worn at correct positions on the body and at correct positions inside and outside the lead garment.
The existing personal dosimeter is a plastic housing in which a tablet is placed, after a test cycle is completed, the dosimeter is retrieved from the laboratory, and then testing and dose estimation work is performed. Currently, the issue and recovery of current personal dosimeters presents the following problems:

At present, personal dose monitoring is issued to a radiological worker after personal dose meter wearing education, and the radiological worker is required to be consciously worn during working. In the monitoring process, the working system of each radiation worker is different, the working time period is different, and the situations that the dosimeter cannot be worn accurately, is stored improperly and can not be worn or is forgotten to be worn when the work is busy often occur.
2. The individual dose monitoring periods are different, generally 1-3 months, the time periods of the monitoring periods of different radiologists are different, and after the period monitoring is stopped, the staff often forget to wear the start time and forget to submit dose cards.
Through retrieval, no management system for personal radiation dose detection of the radiation worker has been found.

In the process, information such as actions of all equipment, touch man-machine interaction actions and the like is uploaded to the server. Meanwhile, the camera records the whole process, video recording can be performed, photos can be shot, and in any mode, the videos and the photos need to be uploaded to a server to be archived.
If the personnel lose the dosimeter, the server generates an alarm message when the specified recovery time is not recovered.
3. Persons entering the radiation zone
The method includes the steps that after a person wears dosimeters, the person moves to a gate of a radiation area, a radio frequency card reading module at an entrance guard remotely reads information of all dosimeter radio frequency cards, a camera acquires face information, and the various information is checked by a server and comprises information of work places, shift times, the number of the radio frequency cards, receiving time and the like of the person.
The server checks the correct person, the large screen at the position displays the simulated portrait, the dosimeters displaying different colors are overlapped according to the number of wearing and the types of the server, the dosimeters are displayed on different body parts of the portrait in a flashing mode, personnel can check the colors and the positions, interaction operation is conducted through the touch control module, and the operation is repeated continuously until all dosimeters are checked.
After the verification is finished, personnel can open the door of the radiation area through fingerprints, keys or access cards and the like and enter the radiation area. If the personnel do not wear enough dosimeters, the large screen can give a prompt, and the entrance guard cannot be opened.
In the process, the camera records the whole process and uploads the whole process to the server. And information such as the time of entering the personnel, the place of the entrance guard, the face of the personnel and the like is automatically uploaded to the server.
If emergency occurs and people need to enter the radiation area quickly, the people can input a password for emergency entrance on the touch control module to finish quick entrance, the action, the entrance time, the people and other information are automatically uploaded to the server, and an alarm message is formed at the server.
4. Persons leaving the radiation zone
When the personnel leave the radiation area, the radio frequency card reading module automatically scans all the radio frequency cards and uploads the information to the server according to the leaving time and identification information such as fingerprints of the personnel, access control cards and the like. And if the number of the radio frequency cards of the personnel is not correct during reading, an alarm message is formed in the server.
5. With persons moving inside or outside the building
When personnel move in a non-radiation area inside and outside a building, the radio frequency card reading module in a corridor, a stair, an elevator, an office and the like can automatically read the information of the passing radio frequency card and upload the passing time to a database of the personnel information corresponding to the passing time in the server.
