AT6130C Radiation Monitor

Compact reasonably priced device intended for gamma radiation ambient dose equivalent and ambient dose equivalent rate measurement.
Features
  • Low weight and small size
  • Automatic compensation of intrinsic detector background
  • Sound and visual alarm in case threshold level is exceeded for dose and dose rate
  • Rapid reaction to statistically significant change of dose rate (measurement process restart)
  • Dose rate and dose thresholds can be selected in entire measurement range and saved when the radiation monitor is switched off
  • Field operation capability over a wide temperature range
  • In search mode each registered gamma quantum is indicated by a sound signal
  • Up to 100 measurement results can be stored in non-volatile memory with information about measurement date and time
  • Measurement results, current time, date and battery life indicator is displayed on matrix LCD screen
  • Bright white backlit LCD-screen
Applications
  • Radiation protective measures in case of nuclear disasters
  • Civil protection
  • Radioecology
  • Fire-fighting service
  • Customs service
  • Dosimetric monitoring in manufacturing facilities, health care and other institutions
Operating principle
Device operating principle is based on the process of count rate measurement of impulses, generated in Geiger-Muller counter tube under the influence of gamma radiation.
Count rate is converted automatically into measurable physical values throughout the range. Energy compensating filter allows correcting energy dependence of sensitivity efficiently in entire energy range of gamma radiation.
Microprocessor-based unit is responsible for controlling the radiation monitor operating modes, calculations, storing and displaying measurement results and for self-checking function.
  
The radiation monitor AT6130C has the pattern approval certificates of Republic of Belarus, Russian Federation, Ukraine, Kazakhstan and Lithuania.
