United Nations system response
The current crisis in Japan -- triggered by the powerful earthquake of 11 March and subsequent tsunami -- is a complex emergency where the United Nations system is responding as and where requested by the Government of Japan.
Damage to nuclear power plants and the resulting risk of radiation mean that human health is now the primary focus of relief efforts. In this, the World Health Organization in Geneva is playing an active role. WHO assesses public health risks and provides technical consultation and assistance. Experts with the International Atomic Energy Agency -- a U.N. agency based in Vienna -- are actively monitoring and reporting on the situation on the ground -- including injuries, radiation levels and in particular containment efforts. The IAEA response team provides assistance and advice to governments and international organizations upon request.
