Radiation Alert Sentry EC Data Sheet

THE SENTRY EC

RADIATION ALERT® PERSONAL ALARMING
RATE METER & DOSIMETER

y x

The Radiation Alert
Dosimeter / Ratemeter designed to ensure the safety
of personnel that work in occupations with potential
x-ray or gamma exposure.

The pocket sized unit has an energy compensated
tube for a linear response to gamma and built in
memory for recording data points for tracking
accumulated exposure. The included SentryCom
Software enables you to generate incident
reconstruction for analysis. The software also permits
you to easily set the vibrating and audio alert to your
desired levels for dose (>1.0 mR/10 µSv) and dose
rate (>1.0 mR/hr/10 µSv/hr).

Use the audio switch to choose between audible clicks
with each count recieved or a discreet silent mode.

SentryCom Software

The optional SentryCom Software enables you
to easily integrate The Sentry into your
radiation safety program by allowing you to
select the thresholds alarms/warnings to your
desired levels for dose (>1.0 mR/10 µSv) and
dose rate (>1.0 mR/hr/10 µSv/hr). You can set
the Cal Factor, and the data logging frequency,
and download the accumulated dose data as

a text le. The report includes a delimited time

and date stamp, exposure, and power cycle

identiers for easy recording and incident

analysis in most spreadsheet programs. Units
of measurement can be changed between mR/
hr and µSv/hr to t your application and report­ing needs.

The SentryCom Software comes complete
with mini-USB cable.
