What does MREM/YR measure?

• A. A measure of the dose of radiation absorbed per year
• B. A measure of lead concentration
• C. A measure of paint thickness
• D. A measure of room volume

Answer: (B)

MREM/YR is a measure of radiation dose exposure over a year. The rem (and its millirem subdivision) quantifies the biological effect of ionizing radiation, not the amount of lead, paint thickness, or room size. So this unit tells you how much radiation a person could receive in a year, which is used to assess safety and regulatory limits. Lead concentration is measured in different units (like ppm or mg/kg), paint thickness in mils or millimeters, and room volume in cubic feet or cubic meters.
