V. Radiological and other controls

Controls are used at accelerator facilities to protect

personnel from exposure to ionizing radiation and

other hazards, which include:

Electrical

Mechanical

Cryogenic

Nonionizing radiation

The design of an effective safety program

incorporates a combination of engineered and

administrative controls.

A. Engineered controls

Engineered controls are the primary controls at

an accelerator facility.

1. Active engineered controls

Active engineered controls include devices

that sense changing conditions and can

trigger a safety action. Examples may

include:

Status lights

Alarms

Interlocks

Scram buttons

2. Passive engineered controls

Once installed, passive engineered controls

are used to prevent personnel entry or reduce

radiation dose and require no further action to
