This concludes the Nuclear Threat unit.

This unit described the hazards and protective measures associated with a nuclear detonation. The energy yield of a nuclear explosion takes the form of blast or shock, thermal radiation, and nuclear radiation. Each of these energy forms has distinct hazards. Radioactive fallout presents a potential long term hazard after the immediate energy yield no longer threatens life or health.

Radiological survey instruments provide the most effective way to determine exposure rates. Once an exposure rate is determined, the "7:10 Rule of Thumb" can be used to predict future exposure rates.
