How to Convert Disintegrations per Minute to Becquerels

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

Formula

becquerels = disintegrations per minute ÷ 59.99988

Step-by-Step Example

Convert 5 dpm to becquerels:

1
Convert 5 dpm to becquerels

We need to convert disintegrations per minute to becquerels

2
Apply the formula

Since 1 Bq = 59.99988 dpm, divide by 59.99988

5 ÷ 59.99988 = 0.0833335

✓
Answer

5 dpm = 0.0833335 Bq

About These Units

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.

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.
