Quantity: One The Inspector Alert Handheld Surface Contamination Monitor The Inspector Alert measures alpha, beta, gamma, and x radiation using a 2-inch pancake GM detector with high sensitivity to common beta and alpha sources. The easy-to-read digital display shows readings in your choice of mR/hr or µSv/hr, CPM, or CPS. The Total/Timer feature allows timed readings from one minute to 24 hours for precise measurement of low-level contamination. An audible alert sounds when the radiation reaches a user-adjustable level. The Inspector Alert meets CE certification requirements for Europe.

Possible Uses· Monitor personal radiation exposure · Monitor an area or perimeter · Detect radiation leaks and contamination · Ensure regulatory compliance · Monitor changes in background radiation · Demonstrate principles of nuclear physics · Check for radioactive minerals in the earth Specifications Sensor Halogen-quenched Geiger-Mueller tube. Effective diameter 1.75" (45 mm). Mica window density 1.5-2.0 mg/cm2. Averaging Periods Display updates every 3 seconds, showing the average for the past 30-second time period at normal levels. Averaging period decreases as radiation level increases. User can select fast 3-second averaging period. Timer Can set 1-10 minute sampling periods in one-minute increments, 10-50 minute sampling periods in 10-minute increments, and 1-24 hour sampling periods in 1-hour increments Display 4-digit liquid crystal display with mode indicators Operating Range mR/hr: .001 to 100.0 CPM: 0 to 350,000 Total: 1 to 9,999,000 counts mSv/hr: .01 to 1,000 CPS: 0 to 5,000 Sensitivity Gamma 3500 CPM/mR/hr referenced to Cs-137 Smallest detectable level for I-125 is .02 mCi at contact Beta C-14 (49 keV avg. 156 keV max.): 5.3% Bi-210 (390 keV avg. 1.2 MeV max.): 32% Sr-90 (546 keV and 2.3 MeV): 38% P-32 (693 keV avg. 1.7 MeV max.): 33% Alpha Am-241 (5.5 MeV): 18% Efficiency For 4 pi geometry at contact Accuracy ± 15% up to 50 mR/hr; ± 20% up to 100 mR/hr Anti-Saturation Readout holds at full scale in fields up to 100 times the maximum reading Count light Red LED flashes with each radiation event Beeper Beeper beeps with each radiation event; can be muted Outputs Dual miniature jack for CMOS or TTL devices, sending counts to computer or data logger. Submini jack for electronic calibration. Power One 9-volt alkaline battery; battery life is average 2160 hours at normal background, average 625 hours at 1 mR/hr with beeper off Size 150 x 80 x 30 mm (5.9" x 3.2" x 1.2") Weight 323 grams (11.4 oz) including battery
