For spot urine samples (tritium analyses), collected on-site with assistance
from FFD personnel.
For 24-hour samples, send kit home and send to a lab.

We are assisting our fire protection engineers with the radioactive release
performance criteria for the NFPA 805 safety evaluation. As part of that
evaluation, we are looking at limits for radioactive materials in areas that
are outside the containment/auxiliary building air handling systems.
We have never posted an area within a CA specifically for > 10k dpm/100cm^2.
So the outer CA would include CA, RP Briefed required for entry, etc, with no
inner boundary. We've sometimes had laydown areas similar to that where we
will put up herculite or similar to contain the contamination,
1. Procell by Duracell
2. Outage use - 6 months, Innage Use - 12 months
3. 1 month
4. We'll occasionally see DMC3000s that have low battery on the racks,
more often during outages. They do seem to run down pretty quickly after
getting a low bat error. For jobs that
DC Cook does not specifically allow skull caps. If workers are in
contamination areas without hard hats, we require hoods. If they have hard
hats, hood use is dependent on work task/contamination potential.

We are looking at streamlining our neutron dose tracking and are wondering how
other plants are performing it.
1. Which do you use for determining neutron dose for workers in Neutron
Exposure Areas:
a. Stay time tracking
b. Gamma to neutron ratios
c. Neutron sensitive
