Hi,
D. C. Cook is looking at streamlining our process for maintaining the
whole-body counters on-site. We would like to know the following.
1. What whole body counters do you use?
2. What is your calibration frequency for whole body counters?
3. What is your frequency for performing a source check on the whole body
counters?
4. Do you perform cross-checks (counting an unknown source to be compared
to an accredited lab) on the whole body counters? If so, at what frequency?
Thanks for your assistance!
