Personal Radiation Dosimeter

The HA3800G monitors occupational radiation exposure from X-rays and gamma rays. It measures the real-time ambient dose equivalent rate and cumulative personal dose equivalent Hp(10). The device alerts users via audible, visual, and vibration alarms when preset thresholds are exceeded, mitigating the risk of excessive radiation exposure.

Product Overview

The HA3800G monitors occupational radiation exposure from X-rays and gamma rays. It measures the real-time ambient dose equivalent rate and cumulative personal dose equivalent Hp(10). The device alerts users via audible, visual, and vibration alarms when preset thresholds are exceeded, mitigating the risk of excessive radiation exposure.

 

Features

  • Simultaneous Readings:​ Displays both cumulative dose equivalent and instantaneous dose equivalent rate.
  • Dual-Level Alarm Thresholds:​ User-adjustable alarm thresholds across the full measurement range.
  • Manual Alarm Mute:​ One-button silence function to temporarily disable the alarm.
  • Exposure Time Timer:​ Countdown timer to remind personnel of time-based radiation protection limits.
  • Tri-Mode Alarm:​ Combines buzzer, LED indicator, and vibration for reliable alerting.
