Convert Femtobecquerels to Millibecquerels
Convert Femtobecquerels (fBq) to Millibecquerels (mBq) instantly and accurately.
Conversion Formula
mBq = fBq × 1.000000000e-12
About Femtobecquerels
The femtobecquerel (fBq) equals 10⁻¹⁵ Bq, used in accelerator mass spectrometry (AMS) to quantify cosmogenic radionuclides (¹⁰Be, ³⁶Cl) in ice cores and geological samples. Ultra-low-background counting in deep underground laboratories reaches the fBq/kg level for solar neutrino detector purity assessment. 1 fBq = 10⁻¹⁵ Bq = 10⁻³ pBq.
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.
