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 invited all Member States to provide UNSCEAR with relevant data about doses from various sources of radiation. The UNSCEAR Secretariat solicited information from designated officers in Member States through four sets of questionnaires:

Medical radiation usage and exposures

The last UNSCEAR report to the General Assembly on these matters was published in the year 2000 and the next report was submitted to the General Assembly in 2008; it is expected to be published in late 2009. In order to prepare this report, Member States were requested in 2001, 2004 and 2006 to consider providing relevant data.

The Secretariat is presently consulting with experts, and with designated officers of Governments and of relevant international organizations, with a view to streamlining collection, analysis and dissemination of relevant information on radiation exposures for the Committee's next cycle, which will commence after 2009.
