DoseGUARD(TM) - RAD-60
Personal electronic alarm dosimeter

DoseGUARD™personal alarm dosimeters are precision instruments for ensuring personal safety. The dose rate or cumulative dose is shown on an LCD display. An audible alarm sounds if a preset dose or doserate is exceeded. The instrument can also be set to give an audible warning of the instantaneous dose rate.

The detector element is a silicon diode. Energy compensation circuits ensure high accuracy (better than 5% at 662 keV, linearity better than 15%). Key parameters are stored in EEPROM and are retained even if the battery is removed. The dosimeter casing is robust and splash proof, and is constructed from smooth high impact plastic for easy decontamination. The instrument has been designed to protect the readings against accidental erasure due to mechanical shock or an RF field. It is battery operated, and requires one standard AAA size alkaline cell.

Features:

  • Digital display of dose rateor cumulative dose
  • Six user-selectable alarm levels on dose and dose rate
  • Self-diagnostic operational checking
  • Robust, splash-proof casing
  • Lightweight design with strong pocket clip
  • Shock resistant
  • Shielded from RF
  • Standard AAA alkaline cell - power reserve of 12 hours after low battery warning
