Overview of Radiation Safety Protection 4 According to the Law of the People's Republic of China on the Prevention and Control of Radioactive Pollution, the Regulations on the Safety Protection of Radioisotopes and Radiation Devices, the Regulations on the Health Management of Radioactive Workers and the Regulations on the Management of Radiological Diagnosis and Treatment, according to the requirements of the administrative departments of environmental protection and health, combined with the actual situation of our hospital, we have established and improved the radiation protection management system and implemented radiation protection measures. Now I briefly report to the leaders as follows:
I. Basic information
Rugao Motou Hospital is a comprehensive, non-profit first-class hospital, located in the neighborhood committee of Gaodeng Village, Motou Town, with an existing business building of 4,506 square meters, employees 126 people and beds of 8 1 piece.
The radiology department is located on the right side of the first floor of the comprehensive business building of the hospital. The radiation workshop is 90 square meters, and the CT machine room and control room are 45,500 MAX line machine room and control room are 45. There are 3 professional technicians, including 2 doctors and technicians 1 person. The main equipment and facilities are: 500max optical diagnostic machine 1, medical diagnostic machine 1, film reading light box 1, microcomputer 3, printer 1.
Second, the protective facilities
(1) environmental safety protection: the central control room shared by the CT machine room and the 500max optical diagnosis machine room is painted with 24cm bricks and 1.5cm barium sulfate, the roof of the CT machine is painted with 3mm lead plate and colored steel tiles, and the 500max optical diagnosis machine room is painted with cast-in-place 12cm concrete. The observation windows in the control room are all lead glass with a thickness of 15cm. The protection effect reaches 3mmPb equivalent. The entrance and exit of doctors and patients in the computer room is 5cm thick, and the inside is lined with 5mm thick lead plates.
(2) Radiation protection equipment: lead apron, lead collar and half-length protective apron.
(3) Three wastes treatment: the radiation generated by the X-ray device in the working process is mainly external X-ray irradiation, which can be shielded by shielding materials. Because of the low energy of X-ray, it will not produce induced radioactive substances in the working process, so there is no need to consider the treatment of radioactive "three wastes"; During the working process, a small amount of ozone and nitrogen oxides will be produced, which can be ventilated by a ventilator.
Third, management measures.
(1) Improve the management organization. The hospital attaches great importance to radiation safety protection, and has set up a "Radiation Safety Protection Leading Group" with vice president in charge of radiation safety, director of radiology, Ding and Sun Hao as members, which is fully responsible for radiation safety protection management in the hospital, organizing the use, storage, emergency treatment and waste recovery of radiation-containing devices and equipment, training and educating radiation workers, publicizing radiation protection knowledge, supervising the implementation of radiation diagnosis and treatment management regulations, and inspecting radiation machinery and equipment and its environment.
(two) to establish and improve the radiation protection safety management system. Operating rules of X-ray machine, operating rules and maintenance measures of Beijing Wandong special X-ray machine, radiation quality control system, radiation protection system, radiation equipment maintenance system, radiation incident reporting system, radiation protection and safety system, personnel training system, radiation personnel health and personal dose management system, radiation post responsibility system, etc.
(3) Emergency treatment. In order to effectively deal with possible radiation accidents, ensure the orderly organization of accident rescue work, minimize or eliminate the impact of accidents and emergencies, avoid the spread and expansion of accidents, and maintain the normal medical work order, an emergency plan for radiation accidents was formulated, and a leading group for emergency treatment of radiation accidents was established with Comrade Shi Lei, vice president, as the deputy head and relevant personnel as members, and the responsibilities, organization and command, and working procedures for emergency treatment of possible accidents were clarified.
Fourth, daily management.
1. In order to enhance the radiation protection awareness of radiation workers and strengthen the training of professional knowledge and basic skills of radiation workers, radiation workers are trained in various ways and forms, and all radiation workers in our hospital are promised to participate in the professional knowledge training of radiation safety and protection organized by provincial and municipal environmental protection departments.
2. Regularly monitor the radiation protection effect, and verify the monitoring instruments and equipment to ensure the normal operation of monitoring. In 20xx, Nantong Center for Disease Control and Prevention qualified the X-ray diagnosis room of our hospital, reported the monitoring results and verification results respectively, and issued the monitoring report and verification certificate.
3, radiation workers health care, one is the health check before mount guard, check regularly after mount guard. Second, the staff must wear a personal badge dosimeter and receive regular testing from Rugao Center for Disease Control and Prevention. On the basis of the above work, in June, 20xx, our hospital submitted the declaration of radiation protection acceptance and safety license to the environmental protection department. From July to September, leaders and experts from municipal and county environmental protection bureaus personally visited our hospital for on-site inspection and technical guidance, and put forward rectification opinions. According to the requirements of the municipal and county environmental protection bureaus, our hospital put forward the Report on Acceptance and Rectification of Radiation Permit Protection Measures, formulated and implemented the rectification measures, and rectified the channels and doors of the radiology department. Door-machine interlocking, warning lights, warning signs, devices to isolate the irradiated patients from the staff, hanging and posting warnings, purchasing radiation monitors, personal badge dosimeters, etc. The radiation protection of our hospital meets the safety requirements after re-examination and acceptance by leaders and experts of municipal and county environmental protection bureaus. On September 9th, 20xx, the Municipal Environmental Protection Bureau issued the Radiation Safety Permit to our hospital.
Although the radiation protection work in our hospital has been greatly improved, there are still some shortcomings. In the future, our hospital should further increase the investment in protection and monitoring facilities and equipment, strengthen management, strengthen monitoring, protection and safety awareness, and ensure the safety of the people and medical personnel.
