Smiths Detection is an authorized Mirion Distributor for Civil ER and Defense Markets in the USA only.

Feature highlights:

  • Loud Alarm, 85 dB (A)
  • Vibrating alarm
  • Highly visible backlit display
  • Optional telemetry
  • Factory upgradeable firmware

Mirion Technologies provides a complete line of hardware and software products targeted to cargo inspectors and emergency responders.

Covering a wide range of X-Ray and Gamma radiation detection, our DMC 3000 Electronic Dosimeter represents over 25 years of real-world electronic dosimetry experience, continually refi ned through customer feedback.
The unique, high contrast and backlit LCD display provides a clear indication of wearer’s dose and ambient dose rate for deep dose equivalent. More importantly, multiple methods (audible, visual, and tactile) are utilized to alert the wearer of alarm conditions.
DMC 3000 provides all of this protection, for over 2500 hours of continuous use, with a single AAA battery.
Mirion Technologies provides users with additional tools for calibration, positive entry control, and remote monitoring.
