A year in orbit: ISS deployment tests radiation detectors for future space missions
The predawn darkness on a cool Florida night was shattered by the ignition of nine Merlin engines on a SpaceX Falcon 9 rocket. The thrust of the engines shook the ground miles away. From a distance, the rocket appeared to slowly rise above the horizon. For the cargo onboard, the launch was anything but gentle, as the ignition of liquid oxygen generated more than 1.5 million pounds of force. After the rocket had been out of sight for several minutes, the booster dramatically returned to Earth with several sonic booms in a captivating show of engineering designed to make space travel less expensive and more sustainable.

Recently developed methods for separation and analysis of radioactive fission gases have been applied to obtain data for an off-gas system of an in-pile loop. A separate in-pile test facility was designed to provide a gas transport stream having fission products having concentrations simulating those anticipated in the off-gas system. Characterization of the radioactivities in this facility provided necessary pre-operational information and specifications for operational and analytical procedures for the off-gas system test.
