[ RadSafe ] Fwd: Effective half life question

[Chris Alston]

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

Subject: [ RadSafe ] Effective half life question
To: radsafe at health.phys.iit.edu


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,
