Convert Rutherfords to Becquerels (Rd to Bq)
1 rutherford (Rd) = 1000000 becquerels (Bq). 1 Bq = 0.000001 Rd. Example: 15 Rd = 15 × 1000000 = 15000000 Bq.

How to Convert Rutherford to Becquerel
- 1 Rd = 1000000 Bq
- 1 Bq = 0.000001 Rd
- Example: convert 15 Rd to Bq: 15 Rd = 15 × 1000000 Bq = 15000000 Bq
Formula
Bq = Rd × 1000000
Derivation from SI units:
- 1 Rd = 10⁶ Bq (obsolete).
- 1 Bq = 1 decay per second (s⁻¹).
Both units are defined exactly, so the factor is exact. Rutherford definition: rutherford; Becquerel definition: becquerel.
Worked examples
- A reading of 2 Rd converts to 2000000 Bq.
2 Rd × 1000000 = 2000000 Bq - A value of 20 Rd is 20000000 Bq.
20 Rd × 1000000 = 20000000 Bq
