is program is cperated to 3rovide continuously updated data on ionizing

radiation deses and dose commitments received sy che residents of islands in
the Northern Marshalls which have Seen ccntaiminated by U.S. atmospheric

nuclear tests.

These data will be used =9 develop predictive dose modelling,

and co provide a basis for remedial actions when necessary.
