Medical uses of radiation

Medical uses of radiological and nuclear technologies benefit patients all across Europe.

Radiological and nuclear technologies provide a wide range of benefits to EU citizens beyond the production of nuclear energy. In particular, they are indispensable in the fight against cancer.

The EU is a global leader on supplying medical radioisotopes and for developing radiological diagnostics and treatments.

It has also led the way in establishing legal standards for quality and safety in radiology, radiotherapy and nuclear medicine. The SAMIRA action plan is the EU’s comprehensive plan to support the safe, high quality and reliable use of radiological and nuclear technology in healthcare.

Benefits of radiation medicine 

Radiological and nuclear technologies contribute significantly to all stages of patient care, including early disease detection, diagnosis, treatment and palliative care.

Radiological imaging procedures, such as mammography and computer tomography, use x-rays for diagnostics as well as planning and guiding treatments. With about 500 million of these procedures carried out annually in the EU, it is by far the most widespread medical application of radiation.

Nuclear medicine uses radioactive substances, mostly to diagnose cancer, as well as cardiac and other diseases. In the EU, about 10 million of these procedures are delivered to patients each year. It is therefore an important tool in cancer management, contributing to early diagnosis and prognostic assessment, and increasingly for therapy.

Radiotherapy uses high-energy x-rays, charged particles or radioactive sources, mostly for cancer therapy. With 1.5 million procedures carried out in Europe annually, it is a crucial part of modern cancer care and among the most effective, efficient and widely used treatments available to patients and physicians.

Modern radiation-based imaging and therapy are constantly progressing, leading to new and improved approaches to diagnosing and treating cancer and other major diseases. Although private investments help support the technological innovation, it will likely not be enough to meet the needs of public health systems. It is therefore important that the EU identifies specific research needs and keeps a dialogue with national authorities, medical professionals, industry, researchers and other key stakeholders.

Radiation exposure

Despite the many benefits of medical radiation technologies, their growing use has also caused a significant increase in the EU population's overall exposure to radiation.

Medicine is now responsible for up to half of the total radiation exposure of EU citizens and more than 90% of the human-made radiation exposure. It is therefore necessary to ensure that radiological imaging procedures are performed strictly in line with clinical needs, as there is a potential for better adapting radiation doses and image quality to diagnostic needs. The rapid pace of technological innovation requires increased availability of improved staff training, equipment upgrades and greater involvement of manufacturers in its clinical use.

EU legal framework and initiatives for radiation protection in medicine

Under the Euratom Treaty, ensuring health and safety with respect to the harmful effects of radiation exposure is a key role of Euratom. It is therefore responsible for establishing the relevant uniform safety standards across the EU. 

In this context, the EU has established an ambitious legal framework for protecting patients, volunteers in medical research and medical staff. It aims to ensure that medical radiation procedures are used only when appropriate and with the minimum clinically needed radiation dose. It also includes strict requirements for staff, procedures and equipment and introduces a number of quality and safety tools, with a particular focus on high radiation doses and/or childhood exposure.

Some aspects of medical applications of radiation are regulated under other legal instruments adopted in line with the Euratom Treaty, such as Directive 2011/70/Euratom on the responsible and safe management of spent fuel and radioactive waste. Relevant aspects are also included under the Treaty on the Functioning of the European Union, for example in Regulation (EU) 2017/745 on medical devices or in Directive 2001/83/EC and in Regulation (EC) 726/20044, both on medicinal products.

Additionally, the Commission has taken a range of legally non-binding initiatives. For instance, in February 2021, the Commission adopted the SAMIRA action plan, which is the first follow-up to Europe’s Beating Cancer Plan and the EU’s first comprehensive plan for action to support the safe, high-quality and reliable use of radiological and nuclear technology in healthcare. The Commission also issues regular publications on radiation protection in the medical sector in the ‘radiation protection series.
