At Ontario Power Generation, urine samples are analyzed by our health physics 
laboratory. 

Fecal samples collected when required and analysis for

C-14 particulate - our lab
Gamma - our lab
Alpha - external lab

Samples containers maintained at sites (Darlington and PICKERING) should they 
be necessary
