Radiation Alert Sentry EC – Personal Radiation Dosimeter & Rate Meter

The Radiation Alert® Sentry EC is a compact personal alarming radiation dosimeter and rate meter designed to help protect personnel working in environments where gamma or X‑ray exposure may be present. Its pocket‑sized design and advanced alerting features make it well suited for continuous personal radiation monitoring.

Energy‑Compensated, Accurate Monitoring

The Sentry EC features an energy‑compensated detection tube that provides a linear response to gamma radiation, improving accuracy across varying energy levels. It measures both dose and dose rate, while built‑in memory stores accumulated exposure data for review and analysis.

Custom Alerts & Event Reconstruction

With the included free SentryCom Software, users can download stored data, perform incident reconstructions, and analyze exposure history. The dosimeter supports customizable audible and vibrating alarms for both dose and dose‑rate thresholds, helping users stay informed when radiation levels exceed preset limits, including:

• Dose alarms (>1.0 mR / 10 µSv)
• Dose‑rate alarms (>1.0 mR/hr / 10 µSv/hr)

Discreet or Audible Operation

An integrated audio mode switch allows users to select between audible clicks with each detected count or a silent mode for discreet operation in noise‑sensitive or controlled environments.

Designed for Personal Radiation Safety

Portable and easy to use, the Radiation Alert® Sentry EC supports real‑time awareness, data logging, and post‑event analysis—helping professionals monitor and manage personal radiation exposure effectively.
