Purpose of a ‘PRD’
The mini rad-D like the radiation pager has many uses. Among those uses are search-detect and surveillance of radiation sources. An example of some of the common uses for PRD’s are:
•Inspection check-points•Border controls•Patrolling large area’s•Discreet monitoring at events•Baggage-vehicle-container searches•Attaching inside of vehicles
The following presentation is not designed as a complete training tool for the use of a PRD but only to illustrate the operational use of the mini rad-D.

Gamma source detection above threshold
Management of the PRD when a gamma source above threshold level is detected.
Flashing LED changes in color and frequency of flash interval as operator approaches the radiation source.
The alarm level (“1” thru “9”) is displayed automatically in real time on the large display. The audio or vibration alert will continue until operator moves away from gamma source. No additional operator activity is required.

Search Procedure
Three search features of the mini rad-D:
1. Radiation intensity is indicated on large LED -scale from “1” to “9” (see below).
2. The small flashing LED will change from orange to red and increase in frequency of flashes as operator moves towards radiation source.
3. The intensity of the audio or vibration alert will increase as the operator moves towards the source – operator not required to view unit to effectively search.
