Characteristics of secondary studies for nonhuman primates exposed to mixed neutron:gamma radiation included in the systematic review.

Source/Authors	Sample size	Radiation Source	Exposure Geometry	Dose Rate
Broerse et al. 1978	15	Mixed neutron:gamma; 300 kVp x-ray	Rotational	28 rad min−1 8 rad min−1
Broerse and Zoetelief 1984	15	Mixed neutron:gamma; 300 kVp x-ray	Rotational	28 rad min−1 8 rad min−1
Farese et al. 1993	5	Mixed neutron:gamma	Posterior anterior	pulse
Farese et al. 1994	5	Mixed neutron:gamma	Posterior anterior	pulse

All studies were published in the open literature or in government publications. Data published in abstracts was not included in the review. The secondary studies did not provide a complete dose response relationship (DRR) but did provide added value of multiple data points in support of the primary DRRs and dose range for high lethal, hematopoietic-acute radiation syndrome.
