Measuring RadioactivityThe unit of radioactive sample activity is the bequerel

1 Bq = 1 count per second = 1 decay per second

The unit of radiation absorbed dose is the gray

1 Gy = 1 J kg-1 = Energy absorbed

Mass

The unit indicating cell damage due to radiation is the sievert

1 Sv = 1 J kg-1 = Absorbed dose (Gy) x Quality factor
