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 Petabecquerels

The petabecquerel (PBq) equals 10¹⁵ Bq. The Chernobyl accident (1986) released ~5200 PBq of noble gases and ~1760 PBq of ¹³¹I; Fukushima Daiichi (2011) released 400-900 PBq ¹³¹I-equivalent; global ⁸⁵Kr inventory from nuclear operations is ~1300 PBq. 1 PBq = 10¹⁵ Bq = 10³ TBq.
