Mean individual dose to Greeks from Chernobyl accident (over 50-year period) is projected to be 260 microSieverts. The collective dose to Greeks over the same period is projected to be 2,500 person-Sieverts. The projections take into account inhalation from the passing cloud, ingestion through the food chain, and external irradiation from deposited radioactivity, and are based on the MESOS dispersion model developed by Helen ApSimon of Imperial College, as applied by W. Nixon, of the Safety and Reliability Directorate of the U.K. Atomic Energy Authority. [Ref: Nuclear News, "Chernobyl doses across the continent", January 1987, p. 62]
