Incapacitation and Performance Decrement in Rats Following Split Doses of Fission Spectrum Radiation

Incapacitation and Performance Decrement in Rats Following Split Doses of Fission Spectrum Radiation

Behavioral incapacitation in rats after exposure to high dose (8-20 krads) fission spectrum radiation was measured with a shock-avoidance jump box. An early transient incapacitation (ETI) which was consistent and dose-dependent lasted from 10-20 minutes after a single pulse of either 8200 or 15 300...

Zusammenfassung:Behavioral incapacitation in rats after exposure to high dose (8-20 krads) fission spectrum radiation was measured with a shock-avoidance jump box. An early transient incapacitation (ETI) which was consistent and dose-dependent lasted from 10-20 minutes after a single pulse of either 8200 or 15 300 rads. This was followed by temporary recovery, permanent incapacitation, and death. There was little or no ETI after a second pulse of 8200 rads, given 30 minutes, 60 minutes, or 24 hours after the first pulse.
