The GammaTest C is a lightweight, rugged, battery-operated dose rate warning device for radiation protection for the detection of gamma and X-ray radiation in the measurand Ḣ*(10) ambient dose equivalent rate. The GammaTest C has four warning thresholds that trigger audible and visual alarms when exceeded Below the warning threshold, the GammaTest C indicates readiness for operation via the red LED and signals increases or decreases in dose rate as an optical single-pulse display by changing the flashing frequency The dose rate warning threshold 25 µSv/h is used in fire department operations to determine the limit of a danger zone according to FwDV 500 The dose rate warning threshold 40 µSv/h is required in the field of non-destructive testing (NDT) for radiographic testing: For mobile handling, the local dose rate must not be higher than 40 µSv/h The splash-proof, anodized aluminum housing provides shielding against electromagnetic influences Operating time with one set of batteries at ambient radiation approx. 250 hours in 24 h operation
