Abstract:

Recent data and methods for predicting the initial radiation exposure at or near the ground surface resulting from the detonation of nuclear weapons were reviewed and evaluated. State-of-the-art methods were then selected or developed for neutron dose, secondary gamma-ray dose from neutron interactions in the air and ground, and fission-product gamma-ray dose occurring during the first minute following a detonation. The neutron and secondary gamma-ray method is based on discrete ordinates calculations of neutron transport in an air-over-ground geometry and first-last collision method for source height effects. The fission-product gamma-ray model is based on Monte Carlo air transport calculations.
