- Small size portable professional device intended for measuring
- Measurement of gamma and X-ray radiation ambient dose equivalent rate.
- Measurement of gamma and X-ray radiation ambient dose equivalent.
- Measurement of surface beta-particles flux density.
PURPOSE OF USE
- Independent measuring channel: gamma-radiation dose power and flux density of beta-radiation
- Continuous measurement with constant specification of the result
- Assessment of the radiological situation by the sound signals (clicks), frequency of which is proportional to the dose power (flux density)
- The resultof measurement with any necessary statistical error
- Automatic restart of the device when changing the type of measured radiation while measuring.
- Compensation of the counting rate due to the presence of gamma radiation while measuring flux density of betaradiation
- Indication of statistical error while measuring
- Indication of unit of measurement
- Indication of the level of battery charge
- Backlight display
- Pocket size
FEATURES
- Sensitivity which is sufficient for correct measurements on the natural background, combined with a high upperlimit of dose rate measurement
- Using the device as a personal dosimeter for automated systems for collecting dosimetric data due to its abilityto transmit time-referenced data about the accumulated dose
- Keeping an internal archive of values of accumulated dose int he non-volatile memory-not less than 2000 records
Possibility to set from 1 to 3 values of alarm level limits and there is a sound in case of exceeding these limits - Control and alternation of parameters is performed using keyboard or PC with specialized software
