Conversion Formula
mBq = PBq × 1.000000000e+18
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 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.
