Unit Definitions:

curie

Ci

Contextual Explanation

Traditional non-SI unit of activity, originally based on the decay rate of exactly 1 gram of Radium-226. Standardized as exactly 3.7 × 1010 disintegrations per second.

Practical Applications

US nuclear regulatory reporting (NRC), historical nuclear energy documentation, commercial isotope distribution catalogs, and high-activity source ratings.

picocurie

pCi

Contextual Explanation

Equal to 10-12 Curie (0.037 Bq or 2.22 disintegrations per minute). Standard unit in the US for expressing extremely low-concentration environmental safety limits.

Practical Applications

Indoor Radon gas concentration testing (e.g., US EPA action limit of 4 pCi/L), public drinking water radioactivity monitoring, and agricultural soil limits.

Example Calculation

To convert 1 curie [Ci] to picocurie [pCi]:
• Conversion factor: 1 curie [Ci] = 1000000000000 picocurie [pCi]
• Step: 1 × 1000000000000 = 1000000000000 picocurie [pCi]
