АТ6130A, AT6130D Radiation Monitors

Compact devices intended for gamma and X-radiation ambient dose equivalent and ambient dose equivalent rate measurement.
 
AT6130A and AT6130D HAVE TWO VARIANTS:
  • w/o PC communication interface
  • with Bluetooth interface
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)
  • Field operation capability over a wide temperature range
  • In search mode each registered gamma quantum is indicated by a sound signal
  • Up to 2000 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
  • Measurement results can be transmittedt to a PC via Bluetooth interface (If available)
  • Headphones can be attached when working in noisy environment
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
Devices operating principle is based on the process of count rate measurement of impulses, generated in Geiger-Muller counter tube under the influence of X and 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 photon radiation.
Microprocessor-based unit is responsible for controlling the radiation monitors operating modes, calculations, storing and displaying measurement results and for self-checking function.
 
 
The radiation monitors AT6130A and AT6130D have the pattern approval certificates of Republic of Belarus, Russian Federation, Ukraine, Kazakhstan and Lithuania.
