7 PRESENTATION
The MiniSentry-2 Computer Based Portable Portal Monitor is a portable emergency gamma portal
monitor. It was designed as a monitoring solution for emergency response to allow the screening of
people exiting a contaminated area, as well as monitoring the entrances to large public gatherings to
detect people who are carrying dangerous radioactive materials. It can also be configured to function as
a vehicle monitor if this option is purchased.
Erection or disassembly can be carried out by one person in less than 10 minutes with no tools
required. The MiniSentry-2 is designed for outdoor as well as indoor use.
The software is adapted to reflect the actual configuration of each model, such as the type, number and
location of detectors and the applicable options. As a result, the screens displayed on different models
may differ slightly from those in this manual; however, the procedures described apply to all units,
except where noted.
