The Chernobyl Forum is the name of a group of UN agencies, founded on 3–5 February 2003 at the IAEA (International Atomic Energy Agency) Headquarters in Vienna, to scientifically assess the health effects and environmental consequences of the Chernobyl accident and to issue factual, authoritative reports on its environmental and health effects.
Nine UN organizations are involved in the Chernobyl Forum:
The Chernobyl Forum also comprises the governments of Belarus, Russia and Ukraine.
The Chernobyl Forum released on 5 September 2005 a comprehensive scientific assessment report on the consequences of the Chernobyl accident titled: "Chernobyl’s Legacy: Health, Environmental and Socio-Economic Impacts". A revised edition was released in March 2006 and is available here, together with the Forum's report "Recommendations to the Governments of Belarus, the Russian Federation and Ukraine".
The report covers environmental radiation, human health and socio-economic aspects. About 100 recognized experts from many countries, including Belarus, Russia and Ukraine, have contributed. The report claims to be "the most comprehensive evaluation of the accident’s consequences to date" and to represents "a consensus view of the eight organizations of the UN family according to their competences and of the three affected countries".
On the death toll of the accident, the report states that 28 emergency workers died from acute radiation syndrome and 15 patients died from thyroid cancer. It roughly estimates that cancers deaths caused by the Chernobyl accident might eventually reach a total of up to 4,000 among the 600,000 cleanup workers or "liquidators" who received the greatest exposures.
One paper estimates an additional 5,000 deaths from the Chernobyl accident among the exposed population of around 6 million living in the contaminated areas of Ukraine, Belarus and Russia However, the paper notes that no significant increased cancer risk apart from thyroid cancer has been scientifically demonstrated to date; this prediction is only an indication of the possible impact of the accident, and should not be taken at face value.
The report quotes 4,000 cases of thyroid cancer resulting from the accident, mainly in children and adolescents at the time of the accident; however the survival rate is almost 99%. Since most emergency workers and people living in contaminated areas received relatively low radiation doses, comparable to natural background levels, no decrease in fertility or increase in congenital malformations have been observed.
