Ken,
We (Duke Energy) give the worker kits. While they don't exactly enjoy this,
they understand once we explain the reason. Our procedure calls for us to
maintain a good supply of kits at each station. We store in a cooler with ice
or dry ice and then ship with dry ice to GEL in Charleston.
You don't want to wait to send the worker offsite. If a significant exposure
to alpha is suspected, by starting immediately and continuing for a total of 7
fecal samples, you are assured of capturing the entire large fraction of the
intake that passes through unmetabolized. This greatly improves the
sensitivity of the analysis and removes most of the uncertainty due to the
difference between the NUREG/CR-4884 model and the actual metabolism of a
particular worker.

South Texas Project would like to know in the event that your plant suspected a
personnel intake of radionuclides that required an evaluation via urine sample
or fecal sample how would you collect the sample? Would you use an outside
agency like a medical facility or send the worker home with a sample
kit/collect on site then send to a lab?
