This device allowed the Apollo 11 astronauts to determine the radiation in the crew compartment. It was fully portable, self-contained, and provided a direct reading of radiation dose rates calibrated in rads/hr. In the event of a radiation emergency (such as a solar flare) it could be used to find a habitable, low-dose region within the spacecraft. During flight it was clamped in a bracket mounted to the Guidance and Navigation conditioning panel.
This unit flown in the Command Module during the Apollo 11 mission and was transferred to the Smithsonian in 1970.
