Which term would most accurately describe the highest category of radiological hazard in transport?

• A. High Level Radiation
• B. Natural Uranium
• C. Plutonium
• D. Smoke Detectors

Answer: (A)

Radiological hazards in transport are described by how intense the radiation is. The term that signals the greatest danger is “high level radiation,” because it indicates materials or sources with high external dose rates and a much greater risk to workers and the public. This descriptor drives the strictest handling, packaging, labeling, and emergency response requirements due to the elevated hazard. Natural uranium and plutonium refer to specific materials with radiological aspects, but they don’t denote a category of hazard level by themselves. Smoke detectors contain only tiny amounts of radioactive material and are considered a very low radiological hazard in transit, not the highest category.
