My 2c worth:

ICRP 2 is getting a bit out of date now but it certainly shows the high
regard in which it was held to have it mentioned 38 odd years after it came
out!

The latest data from the ICRP on this subject is in the series called
*Age-dependent doses to Members of the Public from Intake of Radionuclides*
i.e. ICRPs 56, 67, 69, 71 and 72.  Unfortunately none of these publications
contains a straight listing of biological half-times but there is data
given for a restricted range of nuclides.

The half-time is only one of a number of variables that have been used in
compiling the dose coefficients and the summary listing given in ICRP 72
will be more useful in calculating doses.
