Becquerels (Bq)

Conversion Formula

Bq = nCi × 37

About Nanocuries

The nanocurie (nCi) equals 37 Bq. Sealed radioactive sources in laboratory instruments (electron-capture detectors in GC, ionisation chambers) are licensed in nCi; nCi is the working unit on US NRC licence forms and instrument calibration certificates for low-level sources. 1 nCi = 37 Bq = 3.7 × 10⁻⁸ Ci.

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.
