7. EXPOSURE MONiTORING AND AIR SAMPLING
Air monitoring of potential airborne chemical concentrations was performed during previous
investigation at the YS-60 Firing Ranges. This monitoring indicated no significant airborne
hazards Due to the nature of the work only initial air monitoring will be performed. The need for
additional monitoring will be based on the initial air monitoring results. If levels are at least 30
ugfm, full air monitoring will be performed along with blood lead monitoring. No VOCs are
expected in the area of operation.
The action levels for site monitoring measurements listed in Table 7.1 have been set
conservatively to compensate for monitoring instrument limitations. These instruments will be
calibrated in accordance with manufacturer recommendations and requirements.
Both historical site data and current well monitoring data indicate that there is limited potential
for exposure or contamination of site personnel within the scope of this project. The primary
potential f&r contamination would be from lead in the soil to be removed. Although no radiological
exposure is anticipated during planned site activities, project team members should conduct
radiological screening of their hands and equipment periodically.
A Y-12 Plant HP technician will periodically monitor site operations and the site equipment for
radiologicui contamination. If the HP technician determines the area requires radiological posting,
workwill cease until the areais appropriately posted ordecontmninated. lfrequiredthe level of PPE
will be upgraded by the SHSO and the HP technician. if a radiological area is established, all
workers entering tie area will be required to have completed Radiological Worker 11 training. The
following types ofroutine monitoring will be required.
" All equipment and materials will be monitored for radiological contamination before entering
" Periodic screening for radiological contamination.
* Persons entering known or suspected contaminated areas will monitor or be monitored for
conhtaMl ination prior to exiting those areas.
+ All personnel entering the site will participate in the installation's Dosimetry Program.
Thermoluminescent dosimeters shall be wor at all times while on-site.
" All equipment and materials will be monitored for radiological contamination before being
removed from radiological contamination areas.
+ The following types of monitoring will he performed by the SHSO during this project:
+ Visual monitoring for potential exposure to lead.
* Potential high noise areas will be surveyed to deterin e sound levels using a Type 2 sound levet
meter on the dBA scale.
* Heat stress and cold will be determined by contacting the 1H to request WBCT readings.
Calibration and maintenance of all sampling and survey equipment shall be in accordance with
manufacturer's guidelines, following written procedures, where available.
