How to handle radioactive contaminants.
AU = Authorized user: responsible for handling spills, make cleanup assignments, to control spread of contamination
RSO: Radiation Safety Officer appoints AU
ALARA principle: As Low As Reasonably Achievable, Time , distance, shielding.
Required equipment: Lab coat, closed toe shoes, rubber gloves,
Telephone: telephone required with safety numbers.
Radiation monitor check: Calibration source, integrity check (visible damage to device) , battery check, alarm check
RPR11a & RPR11d: survey maps need to be filled out and displayed, after each work interval with material.
Work area needs: Need trash can with Radioactive Material Label, disposable surface, RAM (Radio Active Material) storage area
Contaminations Surveys: need to survey area to determine if contamination present.
Contamination COntrol: WIpe and fold, push contaminant to highest activity level, with each wipe fold it inward. Clean hand / Dirty hand technique: one hand for radioactive material and one for survey/other work. If unsure which was which, change gloves.
Whole body frisk technique: First do hands then FACTB: Face, Abdomen, Throat, Chest, Back : 1 inch away about moving 1"/sec
Spills: Quantify spill to determine if minor or major spill, ALI = Annual Limit of Intake.
Spill action protocol: SWIM= Secure Warn Isolate(rope off area, close lab,...) Minimize the spread of contamination
