The success of the IARC Monographs rested in part in the impartiality process initiated by Tomatis and his staff, who for each Monograph created working groups of independent scientists with deep knowledge of chemical carcinogenesis, to evaluate all available information on an agent; emphasizing their impartiality and transparency.
In January 1982, in recognition of his outstanding career and contributions inunderstanding cancer causation and prevention, Tomatis was elected by the WHO member nations as the second director of IARC.
