Physics and Radiation Protection

The Medical Physics and Radiation Protection Department is made up of graduates in physics who have qualified as specialists in hospital radiophysics and senior technicians in radiotherapy and/or radiodiagnosis.

The Medical Physics and Radiation Protection Department has accreditation from the Spanish Nuclear Safety Council to carry out radiation protection tasks throughout the hospital. The department is firmly committed to quality and safety, and it has obtained ISO 9001:2015 certification.

The professional activity of the members of the department comprises three main aspects: clinical care, research and teaching.


Our department offers support for all the departments at the hospital that use ionising radiation for patient treatment or diagnosis, and also for the professionals who use radionuclides in their research.

The primary responsibility of members of this department is to ensure effective, risk-free management of radiation, in order to attain the best results in diagnosis or therapy in accordance with what had been prescribed for the patient. This includes protecting the patient, the staff and other people present, as well as the environment, from potential risks or excess radiation exposure.

In order to carry out this task, we establish suitable dosimetry and quality control, measure and characterise radiation, determine the dose administered, and define procedures to ensure good image quality. We also carry out quality assurance programmes and collaborate with other health professionals involved in optimising the balance between the benefit and the risk of using radiation.

Education and Training

Our Department was accredited as a teaching unit for specialisation in hospital radiophysics in 1995. Internationally, this specialisation is known as "medical physics" and involves the application of physics to the field of medicine. The title of specialist in hospital radiophysics is obtained after three years of training as a resident. The Medical Physics and Radiation Protection Department has three residents, one for each year of training.
