We would first, try and decon the area to the acceptable level. If that's not possible we would most likely not allow anyone that is self-briefed access since it doesn't meet the criteria. Also, we would not have a Caution sign with trefoil posted at an area without noting the radiological hazard. ie Radiation Area; Contamination area.

We omitted the Contaminated Area posting to avoid double-posting; the contamination levels were less than 100,000 dpm/100cm2 but greater than 10,000. Our QA department wrote a deficiency CR because the area "does not include a "readily identifiable" type of radiological hazard present, as required by NISP-RP-04, Radiological Posting and Labeling, Section 2.1 and Section 3.2". What do you do to differentiate areas where Self-Briefed workers are not allowed? Thanks John Diehl, CHP STPEGS HP 361-972-8545
