Re[2]: Radioactive Material Thresholds

[BRZGV@CCMAIL.CECO.COM (GLEN VICKERS)]

     I believe there was a recent thread where someone mentioned that 
     personnel might be given waivers to enter high radiation areas and not 
     be officially "monitored".  Consider the following:
     
     
     10CFR20.1502
     
     Personnel shall be monitored if they are likely to receive a dose in 
     excess of 10% of the annual limits or if they enter a high or very 
     high radiation area
     
     
     10CFR20.2104
     
     If personnel will be receiving occupational dose which requires 
     monitoring pursuant to 10CFR20.1502, then the licensee shall obtain 
     the minimum current year exposure and an attempt to acquire previous 
     years dose.  This would typically be collected by an NRC Form 4.
     
     
     The NRC has even issued a clarification for the actions expected of 
     their personnel in the form of a position paper, "Health Physics 
     Position:  Compliance with certain 10 CFR Part 20 Requirements for NRC 
     Employees to be Granted Unescorted Access to Licensee Facilities.  
     Here are a few lines:
     
     Generally NRC personnel are not likely to exceed the 10% rule, but do 
     enter high radiation areas at licensee facilities and are required to 
     be monitored.
     
     The inspector would be expected to provide a signed estimate of the 
     current year exposure to to permit the licensee to comply with 
     10CFR20.2104, but they do not intend to supply previous years dose.
     
     I would think that if the NRC expects their own personnel to be 
     "monitored" under 10CFR20 when entering high radiation areas, then I 
     would think they would want all radiation workers to be monitored when 
     entering a high radiation area.  Any thoughts...
     
     
     Question- Does anyone use anything other than the Form 4 to collect 
     exposure information (10CFR20.2104(d))?

     
     Sincerely,
     Glen Vickers
