The United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), established by the United Nations General Assembly in 1955 to assess and report levels and effects of all sources of ionizing radiation conducts regular surveys of radiation exposure worldwide.

The UNSCEAR online platform is to support governments and international organizations to provide national and regional data on radiation exposure of the public, workers and patients.

National Contact Persons (NCPs) are invited to register here to be able to access the protected area before they can download the questionnaires for official data submission. Additional national experts can be registered to support the NCPs. All contributions will be acknowledged by UNSCEAR in the relevant report to the UN General Assembly.

UNSCEAR is grateful to the (World Health Organization) for establishing arrangements for cooperation which resulted in developing a common medical radiation questionnaire for the survey and to the (European Commission) for permitting the use of the outcomes of the (DoseDataMed II project). Further, UNSCEAR thanks the (International Atomic Energy Agency) and the (International Labour Organization) for the cooperation on the public and occupational radiation exposure surveys, respectively.

Please read further instructions, background information and help if you are interested in using this platform.
