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.
About Millibecquerels
The millibecquerel (mBq) equals 10⁻³ Bq. Radiological surface contamination surveys in nuclear facilities use mBq/cm² alert levels for alpha and beta emitters; uranium and plutonium bioassay in urine from occupationally exposed workers is reported in mBq/sample. 1 mBq = 10⁻³ Bq = 10⁻³ s⁻¹.
