ASN Report 2020

protection measures in patients and their family, carers and comforters where applicable, and the workers that will be required to handle the radionuclides, particularly during their preparation in the hospital. 4.2  Layout rules for nuclear medicine facilities Given the radiation protection constraints involved in the use of unsealed radioactive sources, nuclear medicine units are designed and organised so that they can receive, store, prepare and then administer unsealed radioactive sources to patients or handle them in laboratories (radioimmunology for instance). Provision is also made for the collection, storage and disposal of radioactive wastes and effluents produced in the facility, particularly the radionuclides contained in patients’ urine. Compliance with ASN resolution 2014-DC-0463 Nuclear medicine units must satisfy the rules prescribed by ASN resolution 2014-DC-0463 of 23 October 2014 relative to the minimum technical rules of design, operation and maintenance to be satisfied by in vivo nuclear medicine facilities. This resolution details in particular the rules for the ventilation of nuclear medicine unit premises and the rooms accommodating patients receiving, for example, treatment for thyroid cancer with iodine-131. Guide No. 32 detailing certain aspects of this resolution was published by ASN in May 2017 and was updated in February 2020.
