Cesium-137 (Cs-137) deposition is a good proxy for external gamma dose distribution on a relative basis. Therefore, Cs-137 deposition is a good proxy for distribution of the excess cancers due to external radiation. The two Cs-137 deposition maps show that most of the Cs-137 deposition in the United States was due to global (non-NTS) fallout.Web
