[ RadSafe ] Fwd: Effective half life question

Jeffrey, 

  

If you are talking about prepared pharmaceuticals, these would have package inserts that would include information on the effective half-life for the particular radiopharmaceutical .

There are a multitude of these, depending on exactly what you mean. 
The MIRD Committee publishes reports, and there are ICRP Publications 
53, 80, and 106.  There is also the RADAR website, doseinfo-radar.com. 

But you might want to start with NUREG /CR-6345, Radiation Dose 
Estimates for Radiopharmaceuticals , of April 1996. 

Happy hunting

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 ? 



Thanks,
