FAQ
What is the conversion factor from Bq to dpm?
1 Bq equals 60 dpm. To convert, multiply the value in becquerels by 60.
How do I convert 1 Bq to dpm?
1 Bq = 60 dpm. For any value, multiply by 60.
How do I convert dpm back to Bq?
Divide by the same factor — or equivalently, multiply by 0.01666667. So 1 dpm = 0.0166667 Bq.
When would I need to convert becquerel to disintegration per minute?
Radioactivity (activity) conversions between Bq and dpm are routine in health physics, nuclear medicine ordering, environmental monitoring, radiopharmacy and reactor/accelerator-source documentation. The becquerel (Bq) is the SI unit; the curie (Ci) is the legacy unit (1 Ci ≡ 3.7×10¹⁰ Bq exactly). This category is strictly activity (decays per second) — it does NOT cover absorbed dose (Gy, rad), dose equivalent (Sv, rem), exposure or dose rate, all of which are different physical quantities and live in separate categories.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
