The roentgen is a unit of exposure, not absorbed dose.

🎯 FRCR Part 1 Physics — Radioactive Decay

📝 TRUE or FALSE?
"The roentgen is a unit of exposure, not absorbed dose."

✅ Answer: TRUE ✅

📚 True. The roentgen (R) is indeed a unit of radiation exposure, defined as the amount of X-ray or gamma radiation that produces a specific amount of ionisation in air. It is not a unit of absorbed dose (which is measured in gray).
