Unit Definitions:

millicurie

mCi

Contextual Explanation

Equal to 10-3 Curie (37 MBq). The primary legacy unit still heavily used for clinical radiopharmaceutical dosing in the United States.

Practical Applications

Patient dosing in nuclear medicine (e.g., 10–30 mCi Technetium-99m cardiac scans), industrial thickness gauges, and therapeutic hyperthyroidism treatments.

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.

Example Calculation

To convert 1 millicurie [mCi] to curie [Ci]:
• Conversion factor: 1 millicurie [mCi] = 0.001 curie [Ci]
• Step: 1 × 0.001 = 0.001 curie [Ci]
