Introduction

10 CFR Part 835, Occupational Radiation Protection,

includes provisions for exposure to ionizing radiation

from DOE activities, which includes exposures from

accelerator operations.

II.

DOE Guidance

DOE G441.1-5, Radiation-Generating Devices

Guide, provides guidance on DOE's expectations for

controlling exposure from accelerators (see section

4.3.2.1). The IG refers to applicable ANSI standards

and DOE O 420.2, Safety of Accelerator Facilities.

Article 364 of DOE-STD-1098-99, Radiological

Control, provides similar guidance, and includes

guidance to use the Health Physics Manual of Good

Practices for Accelerator Facilities, SLAC-327, in

meeting occupational radiation protection

requirements for accelerators.

DOE HDBK-1108-97, Radiological Safety Training

for Accelerator Facilities, provides guidance on

DOE's expectations for radiation safety training for

individuals using accelerators.

III. General characteristics of accelerators

Accelerators are devices that increase the speed

and thus the energy of charged particles.

A. Accelerator energy

Accelerators are normally rated by the maximum

energy to which the particles are accelerated.

The energy imparted to the charged particles is

determined by the potential difference measured

in volts (V) in the electrical field. At all but the

smallest accelerators, the acceleration is

accomplished by directing the charged particles

repeatedly through regions containing
