Radiological health standard system of radiodiagnosis and radiotherapy and classification criteria of equipment performance parameters

Objective: To establish a basic radiological health standard system of radiodiagnosis and radiotherapy and to propose a preliminary classification criterion of equipment performance parameters. Methods: The current effective radiological health standards of radiological protection including the testing standards of quality control and radiation protection were confirmed as the investigation object, and they were classified according to their applied scope and implementation property. Then, the equipment testing parameters were studied and weight analyics was made by means of selecting GBZ126 as an example. Results: In the field of current effective health protection of radiodiagnosis and radiotherapy, statistics show that there were 9 standards of quality control and 8 standards of radiological protection respectively by the end of October 2014. On the basis of these criteria, a radiological health standard system of radiodiagnosis and radiotherapy was built and a preliminary classification criterion of equipment performance parameters was formed. Conclusion: The standard system of radiodiagnosis and radiotherapy should be modified, supplemented and perfected deeply on the basis of implementation status of existing standards and the current situation of medical equipment requirements. The reasonable and feasible classification criteria of equipment performance parameters can be proposed only after the relationship between quality control and radiological protection has been taking into account.
