Governments and organizations throughout the world rely on the Committee's estimates as the scientific basis for evaluating radiation risk and for establishing protective measures. >>more

Programme of work
The Committee's programme of work is approved by the General Assembly, and extends typically over a 4-5 year period. The secretariat collates relevant data submitted by UN Member States, international organizations and non-governmental organizations, and engages specialists to analyse those data, to study relevant scientific literature and produce scientific evaluations. The secretariat submits the evaluations annually for scrutiny to each session of UNSCEAR, and at the end of the cycle, the substantive reviews are published.
The Committee has held sixty annual sessions so far. The sixty-first session will take place in Vienna from 21 to 25 July 2014 >>more
The small secretariat in Vienna, which is functionally linked to the United Nations Environment Programme (UNEP), organizes the annual sessions and manages the preparation of documents for the Committee's scrutiny.
