The palmRAD 907 nuclear radiation monitoring meter provides multiple monitoring and surveying options in an easy-to-use handheld device. It measures alpha, beta, gamma, and x-ray radiation which can be displayed in rates and total counts.
Detector: Halogen-quenched Geiger-Mueller tube. Effective diameter 1.75" (45 mm). Mica window density 1.5-2.0 mg/cm
Display: 4-digit liquid crystal display with mode indicators
Averaging Periods: Display updates every 3 seconds, showing the average for the past 30-second time period at normal levels. The averaging period decreases as the radiation level increases. User can select fast 3-second averaging period.
Operating Range: mR/hr: .001 to 100.0; CPM: 0 to 300,000; Total: 1 to 9,999,000 counts; mSv/hr: .01 to 1,000; CPS: 0 to 5,000
Efficiency: Sr-90 (546KeV, 2.3MeV max): approx. 75%; C-14 (156KeV max): approx. 11%; Bi-210 (1.2 MeV max): approx. 64%; Am-241 (5.5 MeV ): approx. 36%
Sensitivity: 3500 CPM/mR/hr referenced to Cs-137
Accuracy: ± 15%
