Radiation therapy, used in the treatment of various diseases, employs ionizing radiation to damage cancer cells. Talking about radiation therapy therefore also means talking about safety, both for patients and for the medical personnel involved.
In this context, the approach to safety must extend from the design of the treatment environments to the management of radioactive waste, through all the intermediate steps.
We discuss this in this article.
Design of dedicated radiotherapy environments
In the field of radiation therapy, the design of treatment environments is the first consideration to ensure a safe and efficient environment. Environments must be designed to maximize treatment accuracy and minimize staff and patient exposure to ionizing radiation.
This includes the strategic arrangement of equipment, such as linear accelerators and simulators, to facilitate easy access and ensure that staff can handle instruments safely and efficiently. The design also takes into account radiological barriers, shields and materials that reduce radiation leakage outside designated areas, as well as ventilation and thermal control systems to ensure comfortable conditions in the treatment environment.
Staff education and training
Staff training is no less important than planning: operators must acquire in-depth skills in radiotherapy equipment handling, treatment planning, and radiological safety.
Training programs should cover a wide range of topics, including basic principles of radiobiology, radiation protection, and emergency procedures. In particular, hands-on training in the use of linear accelerators and other devices is essential to ensure that operators can perform accurate treatments and minimize exposure to patients and themselves.
Continuing education is necessary to keep staff abreast of new technologies and industry best practices. Refresher courses should address topics such as dose reduction, image quality, and technological innovations.
Verification and quality control
Verification and quality control protocols make it possible to ensure the accuracy and reliability of radiation therapy treatments over time.
Daily checks involve measurement of delivered dose, patient positioning, and accuracy of the radiation beam. More in-depth checks, such as beam characterization and evaluation of treatment reproducibility, are required periodically.
These protocols may also include equipment monitoring and emergency management. Documentation of each audit is also essential to demonstrate compliance with regulations, to identify potential areas for improvement, and to identify and correct any deviations or malfunctions in a timely manner.
Radioactive waste management
During processing, waste containing radioactive materials may indeed be generated that requires safe and environmentally sound management and disposal.
Radioactive waste must be collected, stored temporarily and then disposed of in accordance with environmental and safety regulations. This process often involves segregating the waste according to its level of radioactivity and placing it in specially designed containers.
Again, staff training is essential to ensure that all operators are familiar with waste management procedures and use the appropriate equipment.
Local and national authorities strictly regulate radioactive waste management to ensure public safety and environmental protection. Compliance with these regulations is crucial and requires accurate documentation of all steps in the radioactive waste management process. Environmental awareness and the continuous search for innovative solutions are key to ensuring sustainable management of such waste.
The importance of a team of radiation protection experts
Maintaining safety standards in radiotherapy involves a variety of tasks and requires a variety of skills.It is therefore essential for entities that make use of technologies of this type to work with a team of radiation protection experts with extensive know-how who can take the best care of every aspect of the various processes.
