Use the following formula to calculate effective half-life: Where, T is physical half-life, T is biological half-life, and P T is effective half-life. e Let's look at an example: b If the physical half-life of a radionuclide is 12 hours and the biological half-life of the pharmaceutical is 4 hours, what is the effective half-life? Solve the following. 1. Calculate the effective half-life for Tc99m-albumin colloid using the following data: T= 6 hours T = 11 hours P b 2. With a physical half-life of 73 hours and a biological half-life of about 10 days, what is the effective half-life of T1201-thallous chloride? 3. Xe133 has a biological half-life of 0.37 minutes in the lungs, where 68% of the administered dose concentrates. What is the T if T = 5.3 days? P 4. Orally administered P32-sodium phosphate is excreted more rapidly than the IV preparation. It has a biological half-life averaging 5 days. What is the effective half-life for the orally administered radiopharmaceutical? e Use the following formula to calculate effective half-life: Where, T is physical half-life, T is biological half-life, and P T is effective half-life. e Let's look at an example: b If the physical half-life of a radionuclide is 12 hours and the biological half-life of the pharmaceutical is 4 hours, what is the effective half-life?
