Welcome to standardization on nuclear energy, nuclear technologies and radiological protection
Nuclear energy is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons. The main application concerns the civil electricity production in power plants.
The other applications are less well-known. Radiosotopes, nuclear power process heat and non-stationary power reactors have essential uses across multiple sectors, including consumer products, food agriculture, medicine and scientific research, transport and water ressources and the environment
Our scope
Standardization in the field of peaceful applications of nuclear energy, nuclear technologies and in the field of the protection of individuals and the environment against all sources of ionising radiations.
Concretely, ISO/TC 85 contributes to quality, efficiency, radiological protection and nuclear safety by producing international standards in the fields of
- radiological protection
- nuclear installations, processes and technologies
- reactor technology
Our objective
The objective of ISO/TC 85 the production of industrial is the production of industrial standards addressing the needs of nuclear energy, radiological protection, nuclear installations, process and technologies and reactor technology, including:
- measurement of radiation and activity of radioactive materials;
- measurement or calculation of safety or performance-related parameters;
- material specifications, including standard dimension interfaces;
- system specifications;
- operation and maintenance;
- waste management;
- decommissioning;
- conformity assessment and quality management system certification;
- knowledge management;
- assessment of the safety culture and the leadership for safety.
ISO/TC 85 develops standards and tools, through its 2 working groups and its three subcommittees (SC).
More than 40 national standardization bodies take part in ISO/TC 85's activities, led by AFNOR (France).
An active network with 20 international institutional, professional and research organisations has been developed.

Want to get involved?
Standards are developed by the people who need them – that could mean you. Technical committees include experts from both standards and industry and these experts are put forward by ISO’s national members.
Today delegations from 26 national standardization bodies contribute to the standards.
