1. A unit of absorbed radiation dose equal to one thousand rads, used in measuring radiation exposure.
Usage: technical; physics; largely replaced by the gray (Gy) in modern usage

Examples

• The material was exposed to 5 kilorads of gamma radiation during the experiment.
• Radiation safety protocols require monitoring exposure levels in kilorads.
• The sample received a dose of 2 kilorads to test its durability.
• Scientists measured the absorbed dose in kilorads before converting to grays for the report.
