No! Bq is already per second. "Disintegrations per second".

No, you are right. But that slide is showing the different "generalized
particles". In general, DOSE-EQ is in pSv/prim, and only if connected to an
IRRPROFI command become pSv/s.
On the other hand, ACTIVITY and ACTOMASS can exist only in connection to
IRRPROFI, therefore on page 7 the unit can only be per sec (Bq/cm3, or Bq/g)
