Radiation Area Monitor (RAM) - 11.22.16
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).

- The International Space Station (ISS) Radiation Area Monitor (RAM), monitors the interior ionizing radiation environment of the ISS and telemeters that information at regular intervals to ground teams on Earth.
- The solid-state detectors measure radiation dose levels, and information about the directionality and quality of the radiation environment is collected by charged particle spectrometers.
- At set intervals RAMs are attached to structures distributed throughout the ISS, 4-6 RAMs per module and 2-4 RAMs per node.
- Data are stored and analyzed postflight to determine ISS radiation levels.
