All studies for 250 kVp x-radiation, Co-60 gamma radiation, 2 Mev x-radiation and reactor- or nuclear weapon-derived mixed gamma/neutron radiation were published in the open literature or in government publications. The studies provided complete data sets for establishing the dose response relationship (DRR) for mortality versus radiation dose. Data published in abstracts was not included in the review. The radiation source and energy varied from 250 kVp x-radiation to 2 Mev x radiation, Co-60 gamma radiation by moderate or high dose rate and mixed gamma/neutron radiation from steady-state dose rate, pulse exposure and prompt exposure from nuclear weapon detonation.
