IAEA has launched the implementation of a large scale regional project on long term countermeasure strategies and monitoring of human exposure in rural areas affected by Chernobyl.

In addition, the Joint FAO IAEA Division of Nuclear Techniques in Food and Agriculture, in collaboration with the Agency's laboratories in Seibersdorf, Austria, is developing a radionuclide countermeasure information system to address concerns about radionuclide contamination.

Among the issues provided for in the articles was the legal regime on countermeasures, whose codification constituted a safeguard against political and arbitrary countermeasures, and included a set of legality tests which any such countermeasure would have to satisfy.

The wrongfulness of an act of a State not in conformity with an international obligation towards another State is precluded if and to the extent that the act constitutes a countermeasure taken against the latter State in accordance with chapter II of part three.

A financial template was created to help users select countermeasures for contaminated areas. Financial performance indicators are provided for user defined countermeasure projects. A web based version of the economic tool and site specific data, including radionuclide transfer factors, are slated for implementation as resources become available.
