Dosimeter - radiometer MKS-AT6130, MKS-AT6130A and MKS-AT6130D
Compact device intended for ambient dose equivalent rate and ambient gamma and X-radiation dose equivalent rate measurement, as well as for measurement of beta particle flux density on contaminated surfaces. In search mode it measures count rate in counts per second.
MKS-AT6130 HAS 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, dose rate and flux density
- Rapid reaction to statistically significant change of dose rate (measurement process restart)
- Selective measurement of beta and gamma radiation in mixed fields
- Field operation capability over a wide temperature range
- In search mode each registered gamma quantum (beta particle) 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 LCD screen
- Measurement results can be transmittedt to a PC via Bluetooth interface (If available)
- Headphones can be attached when working in noisy environment
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 X, gamma and beta radiation.
Count rate is converted automatically into measurable physical values
throughout the range. Energy compensating filter allows correcting
energy dependence of sensibility efficiently in 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.
Rated sensitivity of each measurement range sets up automatically during calibration procedure.
To facilitate the process of surface contamination evaluation the radiation monitor can be secured in a holder.
The radiation monitors are microprocessor instruments with digital readout. The G-M tube with the energy compensated filter is used is a detector.
