CGS, Response below. Loose contamination? >1000dpm/100cm2 = Contaminated Area (CA), >100,000dpm/100cm2 = High >Contamination Area (HCA).
Is all loose contamination found outside of a CCA classified as loose contamination? Are there instances where it would not be counted as a loose event (floor cleaning, large area masslins, etc...)? NO, if contamination is detected during a routine survey using massilins for Large Area Smears (LAS), >1000dpm/pa/LAS, a follow up survey will conducted using disk smears. If the follow up survey indicates contamination >1000dpm/100cm it would then be posted and documented as a CA. If we find LAS >1000dpm/pa/LAS we will clean the area using massilins or wet mopping until the area is <1000dpm/pa/LAS. Does your station use coveralls as RPPE or civil clothing? Do you use scrubs? Are events on scrubs or other coveralls all counted as PCE's? When would it not be counted? RPPE ? Civil Clothing is allowed inside the Radiological Control Area, Scrubs or modesty garments are required to be worn under Protective Clothing (PCs) no civil clothing is allowed, all contaminations >1000dpm/100cm2 are documented as PCE's Ray Thomson Health Physics Staff Advisor Columbia Generating Station [email protected] Office, 509-377-8273 -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of ALBISHARAT Sasha(A) - BRUCE POWER Sent: Monday, February 06, 2012 11:55 AM To: [email protected] Subject: Powernet: PCE's and loose contamination events Good Afternoon, I was wondering what your plants do for classifications of the following? Loose contamination? >1000dpm/100cm2 = Contaminated Area (CA), >100,000dpm/100cm2 = High Contamination Area (HCA). Is all loose contamination found outside of a CCA classified as loose contamination?
