Convert Microcuries to Becquerels
Convert Microcuries (µCi) to Becquerels (Bq) instantly and accurately.
Conversion Formula
Bq = µCi × 37000
About Microcuries
The microcurie (µCi) equals 3.7 × 10⁴ Bq = 37 kBq. Sealed sources for educational and bench-top laboratory use are licensed up to 1-10 µCi under US NRC 10 CFR 30.18; small-animal PET imaging doses of ¹⁸F in preclinical research are expressed in µCi. 1 µCi = 3.7 × 10⁴ Bq.
About Becquerels
The becquerel (Bq) is the SI coherent unit of radioactivity, defined as exactly one nuclear disintegration per second. Named after Henri Becquerel (discoverer of radioactivity, 1896), it replaced the curie in SI. Household smoke detector ²⁴¹Am sources contain ~30 kBq; a banana contains ~15 Bq of ⁴⁰K. 1 Bq = 1 s⁻¹.
