UNSCEAR Surveys of Global Radiation Exposure

The secretariat of the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) collects and analyses data on the global and regional levels and trends of human exposure to ionizing radiation. In 2014, it had launched the UNSCEAR online platform, which is an electronic web-based database with an automatic importing module for submission of data.

Also in 2014, the UNSCEAR secretariat and the World Health Organization have coordinated arrangements for conducting the UNSCEAR Global Medical Exposure Survey. Information on levels and trends of radiation exposure in medicine since 2006 are collected to expand the previous UNSCEAR 2008 evaluation. Further, the UNSCEAR Global Occupational Exposure Survey was launched in 2016 to provide worldwide information regarding the use and management of radiation exposure at workplaces.

All contributions will be acknowledged in the relevant report to the UN General Assembly.

National Contact Person (NCP)

The General Assembly of the United Nations invited all Member States to provide UNSCEAR with relevant data about doses from various sources of radiation. The UNSCEAR secretariat solicited information from designated National Contact Persons (NCP) for the Committee as officially communicated in the Notes Verbales CU 2014/182 (August 2014),  CU 2016/329 (August 2016) and  CU 2017/311 (August 2017). Thus, Governments are requested to communicate to the UNSCEAR secretariat the name and contact details (including email address) of the official designated NCP who is responsible for the official submission of data to the UNSCEAR secretariat.

Nominated NCPs are required to register to be able to access the UNSCEAR online platform, which fosters secure submission and exchange of data. Additional national experts can be registered to assist the NCP at country level to collect the requested information and data on radiation exposures of the general public, workers and patients.

UNSCEAR's detailed and simplified questionnaires

All Member States are invited to provide some data and information and to contribute to the worldwide estimate of levels of radiological exposure. Technically, these surveys are made through spreadsheet questionnaires, each consists of several work­sheets in order to collect data on medical and occupational exposure separatelyRecognizing that some countries may not have such detailed information, UNSCEAR has developed a simplified questionnaire, in which essential and most recent data is requested. The  competition and submission of the simplified questionnaires is required by 30 November 2017 (extended to 31 December 2017)   and of the detailed questionnaires by 30 June 2018.
