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).

iss049e028948 (10/5/2016) --- Photographic documentation taken during Solid State Lighting Assembly (SSLA) Installation in the starboard Crew Quarters (CQ). The SSLAs were designed to replace General Luminaire Assemblies (GLAs) to improve visual acuity and to provide a crew health countermeasure for circadian rhythms, sleep, alertness and performance. Lighting Effects studies new light sources that can be adjusted for intensity and wavelength across the day, simulating a more regular schedule. Results are expected to provide new information for flight surgeons, psychologists, and crew members to better regulate circadian rhythms and improve sleep.
