Convert Megabecquerels to DPM (MBq to dpm)
1 megabecquerel (MBq) = 60000000 disintegrations per minute (dpm). 1 dpm = 1.666666667 × 10⁻⁸ MBq. Example: 15 MBq = 15 × 60000000 = 900000000 dpm.

How to Convert Megabecquerel to DPM
- 1 MBq = 60000000 dpm
- 1 dpm = 1.666666667 × 10⁻⁸ MBq
- Example: convert 15 MBq to dpm: 15 MBq = 15 × 60000000 dpm = 900000000 dpm
Formula
dpm = MBq × 60000000
Derivation from SI units:
- 1 MBq = 10⁶ Bq.
- 1 dpm = 1/60 Bq.
- 1 MBq = 1000000 Bq ÷ 0.01666666666667 Bq per dpm = 60000000 dpm
Both units are defined exactly, so the factor is exact. Megabecquerel definition: megabecquerel; DPM definition: disintegration per minute.
Worked examples
- A reading of 370 MBq converts to 22200000000 dpm.
370 MBq × 60000000 = 22200000000 dpm - A value of 740 MBq is 44400000000 dpm.
740 MBq × 60000000 = 44400000000 dpm

Where it's used
Megabecquerels are used for PET and SPECT doses (e.g. 370 MBq of F-18 FDG), while disintegrations per minute appear in wipe tests and contamination surveys. Both measure activity of a radioactive source, so the conversion is a fixed factor.

Frequently asked questions
How many disintegrations per minute are in 1 megabecquerel?
1 MBq = 60000000 dpm.
How do I convert megabecquerels to disintegrations per minute?
Multiply the value in MBq by 60000000. For example, 15 MBq × 60000000 = 900000000 dpm.
Is the MBq to dpm conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
