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.

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.
