Hi Claire, below is description of Exelon program. 4.2.2. Routine Passive Monitoring
1. Personnel are routinely monitored for internal dose via the use portal monitors at exit locations. 2. Baseline screening prior to work in a RCA is not a routine requirement. In-processing whole body screens are performed for individuals identified as having a reasonable potential for internal or external contamination. Reasonable potential may include individuals who have recently worked outside the USA or individuals suspected of internal and/or external contamination from another facility. 4.2.3. Periodic Measurements 1. Periodic measurements should be performed at least annually to validate the effectiveness of the bioassay program. 2. A representative sampling of workers (e.g., in the range of 30 to 50 workers) from the identified workgroups should receive scheduled whole body counts. Certain workgroups (e.g., Mechanical Maintenance, Electrical Maintenance, Instrument Maintenance, Station Laborers, Radiation Protection, Fuel Handling, Operating) that frequently perform work activities in airborne or contaminated areas should be selected to participate in a reduced periodic measurement program. 3. Workers may be chosen on the basis of RWPs (and associated air sample data) indicating the highest potential for internal contamination occurring. Radiation Protection should work with schedulers/planners or other persons from affected departments to set up dates and times for performing periodic whole body counts. 4. DETERMINE the appropriate bioassay technique for periodic measurements based on the expected radionuclide(s) of potential exposure for the individual or work group. 5. DOCUMENT, if necessary, any additional bioassay measurements that need to be made for certain individuals or work groups. 6. DOCUMENT all individuals and/or work groups receiving periodic measurements.

My question is, what does your plant do to validate the effectiveness of your passive monitoring program? Do you perform random whole body counts? If so, with what frequency? Does your frequency increase during outages? Thanks for your time, Claire Fage Associate Health Physicist Donald C.
