| |
The new RDS-31S/R Multi-purpose Survey Meter is part of the RDS family of
RADOS survey meters and offers modern design and an advanced approach to
radiation monitoring. The RDS-31 features outstanding ergonomics; it is
lightweight and easy to handle with visual, audible and vibrating alarms. |
| TECHNICAL SPECIFICATIONS: |
| Radiological Characteristics |
radiation detected: gamma and X-rays, 48keV...3MeV. Alpha, Beta radiation with an external • ernal probe
• detectors: one energy-compensated GM tube, energy response according to ambient dose
equivalent H*(10)
• dose rate measurement range: 0.01 μSv/h...0.1 Sv/h or 1 μrem/h...10 rem/h
• dose measurement range: 0.01 μSv...10 Sv or 1 μrem...1000 rem
• resolution: three signifi cant digits or 0.01 μSv/h on dose rate and 0.01 μSv on dose ( 1 μrem/h on dose rate and
1 μrem on dose)
• calibration accuracy: ± 5%, 137Cs , calibration direction and in the calibration fi eld, temperature +20 °C (68°F)
• dose rate linearity: ± 15% ± least signifi cant number 0.05 μSv/h...0.1 Sv/h (5 μrem/h to 10rem/h)

71% <RE, A < 160% (48 keV...3 MeV); ± 60°) |
| Functional Characteristics |
• two buttons to operate the instrument
• confi gurable units: Sv(/h), R(/h), with external detector Gy(/h), cps, cpm, dpm and Bq
• fl exible histogram functions ( dose rate, dose, diagnostic logging depending on confi guration, time stamp,
optional location control for mapping and repeating room measurement analysis)
• additional histogram analyzing capabilities on CSW-software
• real time clock function
