ERIS1D - Radiation and Contamination Monitor

Eris1D

Gamma and X-Rays radiation, and Alpha, Beta, Gamma contamination monitor

  • Two types of measure: Gamma and X-Rays dose rate(ÁSv/h), and Alpha, Beta, Gamma contamination rate (cps)
  • Geiger-MŘller detector with 7 cm² thin window
  • Small, compact and light-weight
  • Two indication modes: Rate and maximum rate (Hold)
  • Two alarm thresholds, in ÁSv/h and cps
  • Self-test with indication of alarms, detector error, low battery, and out of range.

The Eris1D is a handheld, compact and lightweight radiation monitor for detecting and measuring two different types of measures: Gamma and X-Rays dose rate (ÁSv/h), and alpha, beta and gamma radioactive contamination (cps).

The Eris1D has a Geiger-MŘller detector with an open mica window for detecting the alpha, beta and gamma contamination. The measure of contamination rate (cps) is performed placing the energy filter so that the window of the detector is completely open. The measure of equivalent dose rate (ÁSv/h) is performed placing the energy filter so that the window of the detector is completely covered. The way to switch the type of measure is very easy: simply turning the energy filter, covering or not the window. A sensor detects the filter position and sets automatically the measuring type on the display.

The monitor is ready to use as soon as it is turned on and the surfing on the menu is very intuitive and user-friendly. The language of texts and messages are all in English. Its sophisticated firmware calculates the average value of the detected events in last seconds, correcting the dead time of the detector. This reading is very stable, but it is automatically updated when the radiation field varies more than three times the standard deviation of the previous reading. This makes the monitor has a fast response time and steady readings.

Both the dose rate in ÁSv/h and contamination rate in cps have two modes for displaying values: the Rate mode in which the average value is updated each second, and the Hold mode in which the maximum value reached is frozen on the display. Besides they have independent alarm threshold values, which can be set by the user and stored in the non-volatile memory. In case a reading value is above its alarm threshold value, an alarm message will be displayed. The monitor also has self-check routines and displays a warning message if the battery level is low, if the detector fails or if the reading overflows.

After its manufacturing, the Eris1D is tested, adjusted and calibrated. The monitor is supplied with a transport case with strap, with the userĺs manual (in English) and certificates with the results of the measures in equivalent dose rate H*(10) (related to Cs-137) and the results of the calibration factors for some reference isotopes (ISO7503-1).
