1.0 General Description of Operation

The mini rad-D is a highly portable, rugged, all-weather radiation detector that's small enough to wear on a belt
yet powerful enough to quickly locate low-level radioactive sources, even in a warehouse full of boxes. Designed
to discreetly monitor any environment without intrusion or disruption of civilian activities, the mini rad-D can be set
to notify the user by vibration or audible alarm whenever gamma radiation exceeds natural background levels.
The Mini's simple operation and highly readable display provide an automatically updated strength indicator in
less than 1 second, allowing a rapid area sweep to identify the exact location of any radiation source.
When activated, the mini rad-D measures the background radiation count for 30 seconds, and then uses that
value to establish a noise floor. Any radiological isotope that comes within range of the mini rad-D will activate the
audio or vibration alarm, and the mini rad-D display will show a value from "1" to "9" to indicate the radiation
detected. The audio and vibration alarms increase in repetition rate the closer the mini rad-D is brought to the
radiation source. The source of the radiation (package, vehicle, etc....) can be quickly found by waving the mini
rad-D around and using the alarm as a hot/cold indicator. The range of detection can vary from hundreds of
meters to just a few, depending on how large and powerful the radiation source is and how much material is
between the source and the mini rad-D
