Measuring Radioactivity
The 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
