[ RadSafe ] Effective half life question

Hello Radsafers,


I have a question that is related to radiopharmaceuticals. I have been
told by a colleague that the effective half-life of a radioactive
isotope can differ based on the chemical preparation the isotope is in.
Essentially the biological half life will change due to the varying
clearance rates for different chemicals, thereby changing the effective
half-life. Is there a database that addresses the different biological
half-lives for various radiopharmaceuticals?
