iss049e045458 (10/24/2016) --- Photographic documentation of Radiation Area Monitor (RAM) deployed in the Quest Airlock of the International Space Station (ISS). The Radiation Area Monitor (RAM) is a small set of thermoluminescent detectors encased in Lexan plastic that respond to radiation; the amount of radiation they absorb can be revealed by applying heat and measuring the amount of visible light released. The RAM is used to monitor dose and dose equivalent within the habitable volume of the International space Station (ISS) as a function of location, due to its predicted low sensitivity to high-Linear Energy Transfer radiation (neutrons and alpha particles).
