Neutron Exposures

In the possible scenario of a terrorist attack, a possible gun-type detonation of an improvised nuclear device with highly enriched uranium, will produce a substantial neutron exposure risk. As fast neutrons have a much higher relative biological effectiveness (RBE) than gamma rays or x rays, it is expected that the same dose of either of the exposures will have a significantly different biological response. This in turn will translate to different radiation signatures in both urine and blood. In the new round, we aim to characterize the metabolic responses to a mixed irradiation of 3 Gy x rays with increasing percentages of neutrons. All irradiations will be performed at RARAF.
