Evaluation of radiation protection against occupational disease hazards in construction projects


1、Legal basis

According to the "Law of the People's Republic of China on Prevention and Control of Occupational Diseases", "Regulations on the Administration of Radiation Therapy", "Regulations on the Management of Health Examination of Radiation Therapy Construction Projects" and other relevant legal norms, the evaluation of the workplace is required.



2, the purpose of the work

(1) to implement national laws and regulations on radiation health, standards and norms, to control or eliminate occupational hazards at source, to protect the health of radiation workers and the public.

(2) through the review of construction projects and related information, from the perspective of radiation health protection to confirm the legality of the project, the legitimacy of radiation work and the suitability of the workplace.

(3) through the verification and evaluation of the engineering design, to demonstrate the reasonableness of the project's shielding design for radioactive occupational disease protection engineering.

(4) To demonstrate the degree of feasibility through the analysis of safety and protection measures.

(5) To demonstrate the feasibility of putting the project into operation after completion through the analysis of management organization, personnel qualification, regulations and other protective measures.

(6) To propose radiation protection recommendations from the optimization of radiation protection and ensuring the dose limits of relevant personnel for the design and construction units.

(7) Provide technical basis for the administrative approval of the construction project by the health administration department.



3、Evaluation cycle

New construction, expansion, alteration of radiological diagnosis and treatment construction projects, medical institutions should be submitted to the appropriate health administrative departments before the construction of the project occupational disease hazards radiation protection pre-evaluation report.

Medical institutions in the completion of radiation diagnosis and treatment construction projects before acceptance, should be evaluated for the effectiveness of occupational disease hazard control.



4、Workflow

See Figure 1 for details.
