| Detector | Here, are some features of the radiation detector device that is worth mentioning. RAP-RS2 Probe - External Probe Halogen-quenched, uncompensated GM tube with thin mica window, 1.4-2.0 mg/cm2 areal density. Effective diameter of window is 45 mm (1.75 in.). |
| Operating Range | - mR/hr - .001 (1μR) to 100
- CPM - 0 to 350,000
- μSv/hr - .01 to 1000
- CPS - 0 to 5000
- Total Counts- 1 to 9,999,000 counts
|
| Built-In Efficiencies | Sulfur (35S), Strontium (90Sr/y), Cesium (137Cs), Phosphorus (32P), Carbon (14C), Iodine (131I), Cobalt (60Co), and Alpha |
| Energy Sensitivity | Detects Alpha down to 2 MeV. Detects Beta down to .16 MeV; typical detection efficiency at 1 MeV is approx. 25%. Detects Gamma down to 10 KeV through the detector window. 3340 CPM/mR/hr (137Cs). Smallest detectable level for 125I is .02 μCi at contact. |
| Accuracy | - Reference to Cs137
- Typically ±15% from factory, ±10% with NIST Source Calibration NIST
|
| Anti-Saturation | Readout will OVERRANGE in radiation fields as high as 100 times the maximum reading. |
| Selectable Alert Set Range | - mR/hr .001 - 100 and CPM 1 - 350,000. 70db at 1m.
- Pulsating beeper sounds the alert. Adjustable alert levels are used for mR/hr / CPM, and μSv/hr / CPS. Alarm will sound when in Timer Mode when set alarm threshold is reached.
|
| Display | Graphic LCD with Backlight |
| Anti-Saturation | Meter will hold at OVER RANGE in fields as high as 100 times the maximum reading. |
| Averaging Periods | This Radiation detector display updates every 3 seconds. At low background levels, the update is the average for the past 30-second time period. The timed period for the average decreases as the radiation level increases. |
| Outputs | USB for use with Free Observer USB Software for PCs, Bluetooth |
| Count Light | Red LED flashes with each count. |
| Audio Indicator | Internally mounted beeper (can be switched off for silent operation) |
| Power Requirements | USB Power or Two (2) AA alkaline batteries (included). Approx. 800 hrs at background. |
| Temperature Range | -10° to +50°C (14° to 122°F) |
| Humidity | 10% to 70% Non-Condensing. |
| Size | - 140 X 68 X 33 mm (5.5 X 2.7 X 1.3 in.)
- Probe: 260 X 70 X 25 mm (10.25 X 2.75 X 1 in.)
