Exponential

Biologic clearance of material (radioactivity) from the body can be modeled as being

5

Excretion examples

6
New cards

Biologic half-life (Tb)

The biologic clearance will be characterized by a

7
New cards

Effective half-life (Te)

Encompasess both radioactive decay and biologic clearance

8
New cards

Effective half-lives

Must always be shorter than the physical or biologic half-life

1/Te=1/Tb+1/T1/2

The relation between T1/2, Tb and Te is
