Curie to Becquerel (Curie to Becquerel)
Result
37,000,000,000 Becquerel
Formula
Becquerel = Curie × 37,000,000,000
1 Curie = 37,000,000,000 Becquerel, and 1 Becquerel = 2.702702703e-11 Curie.
One gray is one joule of energy absorbed per kilogram; the older rad is 0.01 Gy. One becquerel is one decay per second; the curie is exactly 3.7 × 10¹⁰ Bq.
Worked examples
- 1 Curie × 37,000,000,000 = 37,000,000,000 Becquerel
- 10 Curie × 37,000,000,000 = 370,000,000,000 Becquerel
- 100 Curie × 37,000,000,000 = 3,700,000,000,000 Becquerel
Common mistakes
- Gray measures absorbed energy; the sievert measures biological effect (equivalent dose). They are only numerically equal for X-rays, gamma and beta radiation.
- Becquerels describe how radioactive a source is, not the dose a person receives.
