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 Microbecquerels

The microbecquerel (µBq) equals 10⁻⁶ Bq. Nuclear power plant effluent monitoring reports ¹³⁷Cs and ⁹⁰Sr in air and water at µBq/m³; dietary ²¹⁰Po intake from seafood consumption is assessed at µBq per daily serving in food safety surveys. 1 µBq = 10⁻⁶ Bq = 10⁻³ mBq.
