Monitoring instruments

Special instruments may be needed for monitoring residual activity in materials depending

on:

N Nature of material.

N Physical form (e.g., liquids).

Work areas

Types of work area surveys include:

N Radiation (dose rate) surveys.

N Loose surface contamination surveys.

N Air sampling, including continuous air monitoring.

Items/materials monitoring

EO-17 STATE site requirements for removing material from beam enclosure.

The purpose of monitoring materials is to ensure radioactive materials are identified and

controlled within radiologically controlled areas. All items/materials must be surveyed

prior to removal from areas of potential activation/contamination.

Typically this includes any material inside the beam enclosures, targets and shielded

structures.
