In most labs I have been in, isotopes are routinely used up to
one half-life after the calibration date. We just look up the correction
factor on a chart and do the math. It always works. If you use 
stuff older than one half life, you might be taking chances - we
usually don't try it unless we're desperate ;-)

P.S. No, we don't move that slowly, we just do more cold stuff than hot.
