# Nuclear Weapon Radiation Effects Modeling
**Entity class:** Nuclear-effects prediction domain
## Definition
**Nuclear-weapon radiation-effects modeling** predicts radiation generation, propagation, interaction, exposure, and consequences associated with nuclear-weapon environments. The Oden/DTRA project focused publicly on fast reduced-order prediction of radiation intensity and spread.
