How to Convert Becquerels to Disintegrations per Minute

The becquerel and disintegrations per minute are both units of radioactivity. 1 becquerel equals 59.99988 disintegrations per minute. This means to convert becquerels to disintegrations per minute, you multiply by 59.99988.

Formula

disintegrations per minute = becquerels × 59.99988

Step-by-Step Example

Convert 5 Bq to disintegrations per minute:

1
Convert 5 Bq to disintegrations per minute

We need to convert becquerels to disintegrations per minute

2
Apply the formula

Since 1 Bq = 59.99988 dpm, multiply by 59.99988

5 × 59.99988 = 299.9994

About These Units

Becquerel (Bq)

The becquerel (Bq) is the SI unit of radioactivity, measuring decay rate: one becquerel = one nuclear decay per second. Named after Henri Becquerel who discovered radioactivity in 1896. Human body contains ~7,000 Bq from potassium-40. One curie = 37 billion becquerels.

Disintegrations per Minute (dpm)

Disintegrations per minute (dpm) equals 1/60 becquerel. Standard in liquid scintillation counting and wipe test analysis. One becquerel = 60 dpm. One microcurie = 2.22×10⁶ dpm. Accounts for true activity independent of detector efficiency.
