Prompt Radiation Monitoring

Prompt radiation monitoring is to ensure radiation levels outside of

accelerator facilities are maintained below regulatory limits to workers

and the general public, and as a means to detect deficiencies in beam

containment.

Prompt radiation surveys may utilize fixed and portable

instruments.

Pulsed radiation

Prompt pulsed radiations must be measured with specialized

survey instruments. Ion chambers are typically used.

Neutron radiation.

Neutron monitoring is complicated and should be performed

by an individual qualified to perform neutron surveys.

Residual Radiation

Radioactive materials may be found at accelerator facilities in the form

of:

Activated materials.

Volume contamination.

Residual radiation monitoring

Residual radiation is typically monitored with portable

instruments and contamination swipes. Types of monitoring

may include:

Work areas.

Items/materials.

Operational systems.
