SUMMARY
Following a nuclear detonation, large populations may become externally contaminated due to nuclear fallout. Those who are potentially contaminated will be monitored to determine the necessity of immediate decontamination. Several organizations have suggested generic screening criteria for external contamination; however, inconsistencies remain among these values. Following an improvised nuclear device (IND) detonation, the radionuclide composition of fallout changes rapidly as the large number of short-lived isotopes decay, further complicating the issue. Atmospheric dispersion causes additional variation in the radionuclide composition with respect to distance due to varying particle sizes. |
