EcoGamma-G fixed gamma radiation detector

摘要

Canberra's new fixed EcoGamma-g Geiger-Mueller detector collects gamma radiation data with intensities from 10 nSv/hr to 10 Sv/hr (+/- 15%) in the 30 keV to 3.0 MeV operating range. Temperature data is also automatically recorded. The device consists of two Ne+halogen gas Geiger Mueller detectors, whose crossover point for increasing doses is 500 mR/hr, and on decreasing doses is 300 mR/hr. It connects to a computer via either its single ethernet (1 OBase-T) port or its USB port. Either connection also powers the device. A combination of Rash memory and non volatile RAM memory allows 180 days of data storage at one-minute intervals. It also records total integrated dose (maximum: 100 krad).
