Environmental consequences of the Chernobyl accident and their remediation: Twenty years of experience. Report of the UN Chernobyl Forum Expert Group 'Environment' (EGE). Working material
[en]The purpose of this report is to provide an up-to-date evaluation of the environmental effects of the 26 April 1986 accident at the Chernobyl Nuclear Power Plant. Even though it is now nearly 20 years after the accident and substantial monies have been spent on such evaluations, there are still many conflicting reports and rumours. This joint report has been developed with the full cooperation of the United Nations (UN) family of relevant organisations and with political representatives from the three more affected countries: Ukraine, Belarus, and the Russian Federation. In addition, recognised scientific experts from the three countries and additional international experts provided the basis for the preparation of reports for review by the actual members of the Chernobyl Forum. The - Chernobyl Forum - is a high-level political forum whose suggestion for existence was initiated by the International Atomic Energy Agency (IAEA) in cooperation with the Food and Agriculture Organisation (FAO), the United Nations Office for Coordination of Humanitarian Affairs (OCHA), the United Nations Development Programme (UNDP), the United Nations Environment Programme (UNEP), the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), the World Health Organisation (WHO), and the World Bank, as well as the competent authorities of Belarus, the Russian Federation, and Ukraine. The organisational meeting of the Chernobyl Forum was held on 3-5 February 2003, at which time the decision was reached to establish the Forum as an ongoing entity of the above named organisations. Thus, the organisational meeting of the Forum decided to establish the Chernobyl Forum as a series of managerial, expert and public meetings in order to generate authoritative consensual statements on the health effects attributable to radiation exposure arising from the accident and the environmental consequences induced by the released radioactive materials, to provide advice on remediation and special health-care programmes, and to suggest areas where further research is required; and to accept the following Terms of Reference (TOR) of the Forum. The objectives of the Chernobyl Forum were defined as follows: To explore and refine the current scientific assessments on the long-term health and environmental consequences of the Chernobyl accident, with a view to producing authoritative consensus statements focusing on: the health effects attributable to radiation exposure caused by the accident, the environmental consequences induced by the radioactive materials released due to the accident, e.g., contamination of foodstuffs, and additionally to address the consequences attributable to the accident although not directly related to the radiation exposure or radioactive contamination; To identify gaps in scientific research relevant to the radiation-induced or radioactive contamination-induced health and environmental impacts of the accident, and suggest areas where further work is required based on an assessment of the work done in the past, and bearing in mind ongoing work and projects; To provide advice on, and to facilitate implementation of scientifically sound programmes on mitigation of the accident consequences, including possible joint actions of the organizations participating in the Forum, such as: agricultural, economic and social life under safe conditions, special health care of the affected population, monitoring of the long-term human exposure to radiation, and addressing the environmental issues pertaining to the decommissioning of the Shelter and management of radioactive waste originating from the Chernobyl accident. The Chernobyl Forum itself continued as a high-level organisation of senior officials from UN agencies and the three more affected countries. The actual work has been accomplished by two expert groups: Expert Group -Environment - (EGE) and Expert Group 'Health' (EGH). Members of each of these two groups consisted of recognised international scientists, including those from the three more affected countries. Within these two groups and their subworking groups the draft documents to support this report were prepared for consideration by the members of the Forum. The EGE was coordinated by the IAEA and the EGH was coordinated by the WHO. In all cases the scientists from the UN organisations, the international community, and the three affected countries have been able to reach consensus in the preparation of their respective draft documents. After approval by the members of the Forum itself and final editing of the draft documents, this report is the result of that process regarding the environmental consequences of the Chernobyl accident. A similar report on the health effects attributable to radiation exposure arising from the accident has been prepared for Forum consideration and approval by the Expert Group 'Health'
