Terabecquerel (TBq)
A terabecquerel is 10¹² decays per second, about 27 curies: the scale of radiotherapy and industrial gamma sources.
Symbol: TBq
Quantity: activity of a radioactive source
SI relation: 1 TBq = 1000000000000 Bq (exact)
Derivation: 1 TBq = 10¹² Bq.
Exact: yes, by definition
Typical uses
- Cobalt-60 and iridium-192 sources
- Releases from nuclear incidents
