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 Nanobecquerels

The nanobecquerel (nBq) equals 10⁻⁹ Bq. Atmospheric surveillance for tritium and ¹⁴C near nuclear facilities reports discharge rates in nBq/m³; EU drinking water directives set indicator activity concentrations for some radionuclides at the nBq/L level. 1 nBq = 10⁻⁹ Bq = 10⁻³ µBq.
