UNSCEAR surveys of global radiation exposure
UNSCEAR collects and analyses data on the global and regional levels and trends of human exposure to ionizing radiation.
The General Assembly of the United Nations has invited all Member States to provide UNSCEAR with relevant data about doses from various sources of radiation. The UNSCEAR Secretariat solicits information from designated officers in Member States through four sets of questionnaires:

The last UNSCEAR report to the General Assembly on these matters was issued in the year 2000 and the next report is envisaged for 2008. In order to prepare this report, Member States were requested in 2001, 2004 and 2006 to consider providing relevant data.
The Secretariat is planning to consult with designated officers of Governments and of relevant international organizations with a view to developing more efficient mechanisms for collecting, analysing and disseminating relevant information on radiation exposures for the Committee's next cycle, which will commence after 2008.
