hazards. Periodic monitoring of airborne levels with real-time monitors is critical, especially

before and during new work activities.

Where appropriate, screening with direct-reading instruments for ionizing radiation should be

conducted prior to and during site activities. Where appropriate, the type of radioactive isotopes

present should also be identified to assure that action levels, worker exposure and environmental

standards are not exceeded.

A summary of direct-reading instruments to be used and their specific operating parameters

should be developed. An example is provided in Table 8-4.

8.4.2. Time-Integrated Sampling Instruments

Time-integrated sampling for chemical and radiation hazards should be performed prior to and

during site activities. The equipment and collection media to monitor each hazard should be

specified. Time-integrated sampling may include pumps, collection media (MCE filters, AA

filters, sorbent tubes), and badge-type passive samplers.

8.5. WORKER EXPOSURE MONITORING

The sampling strategy chosen to assess worker exposure through time-integrated sampling and

the sampling results should be documented. Sections 8.11 through 8.14 contain additional

guidance on documentation and recordkeeping. Personal monitoring samples for both

radioactive isotopes and chemicals should be collected in the worker's breathing zone.

Representative sampling of those employees with the greatest risk of exposure is required in

accordance with 1910.120(h)(4). The sampling strategy should be documented and changed as
