The Ghana Atomic Energy Commission (GAEC) is the state organization in Ghana involved with surveillance of the use of nuclear energy in Ghana. It is similar in aim to the Ghana Nuclear Society (GNS), with the difference being that the GNS is a nonprofit organisation, whereas the GAEC is part of the parliament of Ghana. Its primary objectives were set out by the parliament act 588, which involve investigating the use of nuclear energy for Ghana and supporting research and development both in Ghana and abroad.

The International Commission on Non-Ionizing Radiation Protection (ICNIRP) is an international commission specialized in non-ionizing radiation protection. The organization's activities include determining exposure limits for electromagnetic fields used by devices such as cellular phones.
Forschungszentrum Jülich is a member of the Helmholtz Association of German Research Centres and is one of the largest interdisciplinary research centres in Europe. It was founded on 11 December 1956 by the state of North Rhine-Westphalia as a registered association, before it became "Kernforschungsanlage Jülich GmbH" or Nuclear Research Centre Jülich in 1967. In 1990, the name of the association was changed to "Forschungszentrum Jülich GmbH". It has close collaborations with RWTH Aachen in the form of Jülich-Aachen Research Alliance (JARA).

Its composition is being coordinated through the National Academy of Sciences of Ukraine.

The National Nuclear Energy Commission is the Brazilian government agency responsible for orientation, planning, supervision, and control of the Brazil's nuclear program. The agency was created on 10 October 1956. The CNEN is under the direct control of the Ministry of Science and Technology.
Norwegian Radiation Protection Authority is a Norwegian public agency under the Ministry of Health and Care Services headquartered in Østerås, Bærum municipality, Greater Oslo Region. It works as an authority in the area of radiation protection and nuclear safety. NRPA falls under the Ministry of Health and Care Services, but serves all ministries and departments on issues relating to radiation.

The Nuclear Emergency Support Team (NEST), formerly known as the Nuclear Emergency Search Team, is a team of scientists, technicians, and engineers operating under the United States Department of Energy's National Nuclear Security Administration (NNSA). Their task is to be "prepared to respond immediately to any type of radiological accident or incident anywhere in the world".

The Nuclear Energy Agency (NEA) is an intergovernmental agency that is organized under the Organisation for Economic Co-operation and Development (OECD). Originally formed on 1 February 1958 with the name European Nuclear Energy Agency (ENEA)—the United States participated as an Associate Member—the name was changed on 20 April 1972 to its current name after Japan became a member.

Pacific Northwest National Laboratory (PNNL) is one of the United States Department of Energy national laboratories, managed by the Department of Energy's (DOE) Office of Science. The main campus of the laboratory is in Richland, Washington.

The Physikalisch-Technische Bundesanstalt (PTB) is the national metrology institute of the Federal Republic of Germany, with scientific and technical service tasks. It is a higher federal authority and a public-law institution directly under federal government control, without legal capacity, under the auspices of the Federal Ministry for Economic Affairs and Energy.

Safecast is an international, volunteer-centered organization devoted to open citizen science for environmental monitoring.

The United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) was set up by resolution of the United Nations General Assembly in 1955. 21 states are designated to provide scientists to serve as members of the committee which holds formal meetings (sessions) annually and submits a report to the General Assembly. The organisation has no power to set radiation standards nor to make recommendations in regard to nuclear testing. It was established solely to "define precisely the present exposure of the population of the world to ionizing radiation." A small secretariat, located in Vienna and functionally linked to the UN Environment Program, organizes the annual sessions and manages the preparation of documents for the Committee's scrutiny.
