Rutherford (Rd)
The rutherford (Rd) is an obsolete unit of one million decays per second, equal to 1 MBq.
Symbol: Rd
Quantity: activity of a radioactive source
SI relation: 1 Rd = 1000000 Bq (exact)
Derivation: 1 Rd = 10⁶ Bq (obsolete).
Exact: yes, by definition
Typical uses
- Older nuclear physics literature
