The effective half-life is the biological excretion along with the radioactive decay after a radiopharmaceutical enters a body. The effective half-life can be represented as: 1 T E = 1 T B + 1 T p. T E = Effective Half-life. T B = Biological Half-life. T P = Physical Half-life. Rearranging the above yields: T E = T ...
