The typical PIC (Pocket Ionization Chamber) will be essentially 
useless as a secondary monitoring device. The PIC will under-
respond (if at all) to typical accelerator energy spectrum. The other 
problem you'd have is you'd need a reader to zero it out, from 
response due to natural background, transit exposure, etc.

If you're going to wear anything, you should use an electronic 
dosimeter (still need the capability to zero it out - or, just do the 
simple subtraction from day to day). They should wear a TLD and 
ensure that the appropriate algorithm is used to report the dose, 
upon their return.
