UNSCEAR's Global Radiation Exposure Surveys  

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 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 Occupational Exposure Survey was launched in 2016 to provide worldwide information regarding the use and management of radiation exposure at workplaces. The UNSCEAR Public Exposure Survey is planned to be launched at the end of 2020.

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), CU 2017/311 (August 2017), CU 2018/73 (February 2018) and CU 2020/242 (June 2020). 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 exposure of patients, workers and the general public.

All contributions will be acknowledged in the relevant reports to the UN General Assembly. UN Member States and their organizations that have already nominated NCPs to UNSCEAR are listed here .

UNSCEAR's surveys 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, occupational and public exposure separately. Recognizing that some countries may not have such detailed information, UNSCEAR has developed a simplified questionnaire for each topic, in which essential and most recent data are requested. The competition and submission of the simplified and the detailed questionnaires is required on regular base.
