When radionuclides are used pharmacologically, for example in radiation therapy, they are eliminated through a combination of radioactive decay and biological excretion. An effective half-life of the drug will involve a decay constant that represents the sum of the biological and physical decay constants, as in the formula: With the decay constant it is possible to calculate the effective half-life using the formula: WebBased on the last equation, half life is the value of t for which N=N0/2. If we replace this in equation 3, we obtain: N02=N0e-t1/2. (4) Solving this equation for t1/2 yields: t1/2=ln (2) (5) This means we can determine an element’s half life by measuring its decay constant from experimental data. howl\u0027s moving castle full movie japaneseWebThe effective half-life is the biological excretion along with the radioactive decay after a radiopharmaceutical enters a body.
