Image 78: View into a hot laboratory. Technician Dan Gardner examines irradiated materials using remotely controlled manipulator arms from behind protective walls and shielded windows. (NASA CS–22201) Image 79: The hot laboratory’s safe workarea. Operators are using manipulator arms to work with irradiated experiments in the cells. The hot lab also contained an office, manipulator repair shop, and a decontamination room that connected this “clean” operating area with the radioactive area behind the cells. (NASA C–2003–839) Plum Brook’s Nuclear Facilities 89 Image 80: A health-physics technician uses a hand-held “cutie pie ” radiation detector to check equipment for contamination. These detectors allowed technicians to quickly monitor specific areas or equipment. They worked in conjunction with the permanent systems that constantly monitored radiation levels throughout the facility. (NASA C–2003–840) 90 NASA’s Nuclear Frontier: The Plum Brook Reactor FacilityImage 81: Identical Remote Area Monitoring System (RAMS) detector location panels, found in both the health-safety operations office and the reactor control room, and other monitoring equipment allowed operators to monitor radiation sensors located throughout the facility and to scram the reactor instantly if necessary. The color of the indicator lights corresponds with the elevation of the detectors in the various buildings. The reactor could also shut itself down automatically if monitors detected any sudden irregularities. (2001) (NASA C–2001–01150) Image 82: A Plum Brook technician wearing protective clothing and a mask washes contaminated clothing. The clothing was worn again after it was decontaminated and laundered. The wash water had to be treated as radioactive waste. (2001) (NASA C–2003–841
