The European ALARA Network
The European ALARA Network (EAN) promotes the optimisation of radiation protection (keeping exposures As Low As Reasonably Achievable – ALARA) across Europe. It brings together professionals, regulators, and stakeholders to share experience, develop guidance, and support the practical implementation of ALARA principles in various sectors, including industry, medicine, research, and the environment.

Legal provisions

The use of ionising radiation in medicine in Switzerland is regulated by several ordinances. The Radiological Protection Ordinance provides a general framework and more detailed requirements are specified in technical Ordinances, such as the “Use of unsealed sources”, the “Use of sealed sources in medicine” and the “X-ray” Ordinances. In radiation therapy, requirements regarding Quality Assurance, such as dosimetry checks, are specified in the Ordinance on Medical Accelerators, with full details for the application given in the Swiss Society of Radiobiology and Medical Physics (SSRMP) Recommendation 11.
