Curies are a measure of which quantity?

Explanation:
Curies measure radioactivity—the rate at which a radioactive substance undergoes disintegration. It tells you how many atomic decays occur each second. A Curie equals 3.7 × 10^10 disintegrations per second, which shows it’s a unit of activity, not of temperature, volume, or mass. In modern practice, the SI unit is the Becquerel (1 disintegration per second), so 1 Curie is 37 × 10^9 Becquerels. This helps explain why measurements of radioactive materials, or things like radon levels, are tied to activity rather than weight, temperature, or volume.
