Megabecquerel (MBq)
A megabecquerel is one million decays per second, equal to 27.03 microcuries. Diagnostic nuclear-medicine doses are prescribed in MBq.
Symbol: MBq
Quantity: activity of a radioactive source
SI relation: 1 MBq = 1000000 Bq (exact)
Derivation: 1 MBq = 10⁶ Bq.
Exact: yes, by definition
Typical uses
- PET and SPECT doses (e.g. 370 MBq of F-18 FDG)
- Radiopharmacy dispensing
