What does RAM stand for in radiation safety?

• A. Radiation Attenuation Measure
• B. Radioactive Material
• C. Radiation Access Mode
• D. Residual Activity Metric

Answer: (B)

In radiation safety, RAM refers to a designation used for items that contain radioactive substances and require safety controls. The correct expansion is "Radioactive Material." This label triggers proper handling practices across packaging, labeling, storage, transport, and waste management, ensuring regulatory compliance and protecting people and the environment.

The other terms describe different ideas: attenuation relates to how much a material slows or reduces radiation, an access mode would imply a way to reach something rather than what it is, and residual activity metric would measure remaining radioactivity after processing. Those concepts are not the designated meaning of RAM in safety documentation, so they don’t fit as the correct expansion.
