QuestionAnswer
What are the limitations to the AN/VDR-2? Will only retain memory for 5 minutes after batteries are removed if MWO has not been done, after MWO memory stays indefinitely and has a 2 second detecting delay and reduced accuracy for 10 Gy/hr
What are the measuring gamma capabilities of the AN/VDR-2? Detects, measures, and displays dose rate from 0.01 Gy/hr to 100 Gy/hr
What are the measuring beta capabilities of the AN/VDR-2? Detects, measures and displays dose rate from 0.01 Gy/hr to 5cGy/hr
What are the measuring capabilities of the AN/VDR-2? Measres, stores and displays accumulated does (total does) from 0.01 Gy to 9.99 Gy and flashing to display measuring from 10 Gy/hr and above
What technology does AN/PDR-77 use? Geiger Muller for beta/gamma and scintillators for alpha/X-ray
What are capabilities of the AN/PDR-77? Contains X-ray probe, alpha paddle, auto ranging and designed to find fissile material dispersed from an incident involving nuclear weapons
What are the measuring alpha and beta capabilities of the AN/PDR-77? Detects, measures and displays dose rate from 0-999K CPM, 180 uCi/m2, 0-999K DPM/100 cm2, detects and displays level of beta radiation does rate from 0-999 mR/hr
What are the measuring gamma and x-ray capabilities of the AN/PDR-77? Detects, measures and displays dose rate from 0-999K mR/h and 0-999 CPM
What are the limitations of the AN/PDR-77? Requires multiple probes to detect different kinds of radiation
What technology does the identiFINDER use? Thallium-activated sodium iodide [NaI(Tl)] detector and geiger-muller tube
What are the capabilities of the identiFINDER? Provides gamma dose and dose rate, 74-item on-board library of radionuclides that can identify radioactive sources and waterproof
What are the limitations of the identiFINDER? Can not be serviced by the operator and 8 hour battery life
