The Use of Electron Linear Accelerators in Medical Radiation Therapy. Overview Report No. 4. Regulations,Standards and Guidelines.

摘要

The report is the last in a series of four overview reports prepared during the course of a study regarding the use of electron linear accelerators in radiation therapy. This report presents an overview of the regulations,standards,and guidelines which currently affect the design and use of electron linear accelerators in medical radiation therapy in the United States. General regulations,standards and guidelines for radiation safety,which affect accelerator design and use,are discussed,but more specific attention is given to control mechanism which are related to the delivery of a useful properly controlled prescription dose of radiation to the patient and to minimizing the possibility of the delivery of a potentially harmful dose of radiation to the patient,machine operators,or others in the vicinity of the accelerator.
