Unit Definitions:

rutherford

Rd

Contextual Explanation

A non-SI legacy unit of radioactive decay rate defined as exactly 1,000,000 disintegrations per second (1 MBq). Introduced in 1946 to replace the Curie with a decimal-based system.

Practical Applications

Historical nuclear physics literature (1940s–1950s) and early radiometric dating calculations prior to the universal adoption of the Becquerel system.

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 rutherford [Rd] to curie [Ci]:
• Conversion factor: 1 rutherford [Rd] = 0.00002702702703 curie [Ci]
• Step: 1 × 0.00002702702703 = 0.00002702702703 curie [Ci]
