Applying radiation protection and safety in radiotherapy.

Radiotherapy is one of the primary treatment options in cancer management. Modern radiotherapy includes complex processes requiring many different kinds of expertise. Among them, knowledge and skills are needed in clinical oncology, radiobiology, radiotherapy planning and simulation, dose measurement and calculation, radiation safety and medical physics. Radiation oncologists should assume the full and final responsibility for treatment, follow-up and supportive care of the patient. For all these activities, radiation oncologist should coordinate and collaborate with a team including different professionals: nurses, radiographers (RTT), clinical engineers, information system experts, taking advantage in particular of the dosimetry expertise of the medical physicist. Radiation therapy is widely recognized to be one of the safest areas of modern medicine, and errors are very rare. However, radiation protection recommendations developed at national level should comply with the EURATOM Directive 2013/59. This paper describes several contemporary and emerging concerns related to radioprotection in radiation therapy including quality and safety in external beam radiotherapy and brachytherapy, foetal dose, secondary malignancies, and the safety issues related to the new techniques and treatment strategies.
