ATOMTEX AT6130A Pocket Radiation Monitor Instruction Manual

ATOMTEX AT6130A Pocket Radiation Monitor

Compact devices intended for gamma and X-radiation ambient dose equivalent and ambient dose equivalent rate measurement.

Operating principle

The device operating principle is based on the process of count rate measurement of impulses, generated in a Geiger-Muller counter tube under the influence of X and gamma radiation. The count rate is converted automatically into measurable physical values throughout the range. An energy-compensating filter allows for correcting energy dependence of sensitivity efficiently in the entire energy range of photon radiation. Microprocessor-based unit is responsible for controlling the radiation monitor operating modes, calculations, storing and displaying measurement results, and for self- checking function.

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

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 are displayed on the matrix LCD screen
• Headphones can be attached when working in a noisy environment
• Bright white backlit LCD screen
• Display in either Sv/h or in rem/h (configurable per request)
