MODULE 104 - RADIATION DETECTION

OBJECTIVES

Module Objective.

Upon completion of this unit, the participants should understand which radiation-

monitoring instruments and which personnel-monitoring devices are appropriate for

detecting X-rays.

ii. Objectives.

Following self-study and/or classroom review, the participants will be able to:

Identify the instruments used for X-ray detection and

Identify the devices used for personnel monitoring.

RADIATION SURVEYS

Radiation protection surveys should be conducted on all new or newly installed X-ray devices

by the X-Ray Device Control Office (or facility-specific equivalent) and repeated at a

frequency determined by site policies.

X-RAY DETECTION INSTRUMENTS

External exposure controls used to minimize the dose equivalent to workers are based on the

data taken with portable radiation-monitoring instruments during a radiation survey. An

understanding of these instruments is important to ensure that the data obtained are accurate

and appropriate for the source of radiation.

Many factors can affect how well the survey measurement reflects the actual conditions,

including:
