What does 1 curie represent in terms of nuclear decays?

One curie (Ci) equals 3.7 × 10¹⁰ nuclear decays per second, originally defined as the activity of one gram of radium-226.

Why convert curies to picocuries?

Converting curies to picocuries allows expressing radioactive activity at smaller scales, which is important for environmental monitoring and health risk assessments.

Are there any challenges with converting from curie to picocurie?

Yes, handling the very large numbers resulting from the conversion can be difficult, and accurate low-level measurements in picocuries require sensitive equipment.
