While these are conservati~-e standards from a health \riew point, there is no built-in conservatism to account for uncertainty in prediction of annual exposures to indi>tiduals. Because of the complex circumstances of exposure and the many pathways, each with its uncertainty, the Task Group recommends use of 50 percent of the FRC annual staric?ards for evaluation of the many cleanup and rehabilitation alternatives at Enewetak Atoll.
