Convert Disintegrations per minute to Megabecquerels
Convert Disintegrations per minute (dpm) to Megabecquerels (MBq) instantly and accurately.
Conversion Formula
MBq = dpm × 1.666666667e-8
About Disintegrations per minute
The disintegration per minute (dpm) equals exactly 1/60 Bq ≈ 16.7 mBq. Standard output unit of liquid scintillation counters (LSC) in biochemical and biomedical research for ³H and ¹⁴C tracer assays; radioimmunoassay protocols report results in dpm/well. 1 dpm = 1/60 Bq = 60 dph.
About Megabecquerels
The megabecquerel (MBq) equals 10⁶ Bq and is the standard clinical nuclear medicine unit outside the US. ⁹⁹mTc bone scans use 740 MBq; ¹⁸F-FDG PET scans use 370 MBq; ¹³¹I diagnostic thyroid scans use 185-370 MBq. European and Australian protocols specify all doses in MBq. 1 MBq = 10⁶ Bq.
