The total population The greatest population exposures occurred in three genera? areas: Saint George, Utah; Ely, and Las Vegas, Nevada. Three events, HARRY (May 19, 1953), BEE (March 22, 1955), and SMOKY (August 31, 1957), accounted for ouer half of the total population estimated exposure. The bases of the caiculational models for “infinite exposure," “estimated exposure," and’"one year effective biological exposure” are explained. 201
