The radiation environment in space is very different than anything routinely encountered on Earth. This makes assessing the risk of the exposure problematic, and presents special requirements for dosimetry measurements. Recently, the Relativistic Heavy Ion Group at the University of Houston has engaged in adapting the active pixel detector technology used in the major experiments at the Large Hadron Collider at the CERN laboratory in Geneva, Switzerland to the development of space radiation detectors. Currently there are 5 such detectors deployed and taking data on the ISS, and evolutions of these basic devices are planned to be used on the upcoming test of the new US manned spacecraft, the Orion module, during its first unmanned test flight. Beyond that, NASA has plans to deploy future incarnations of the technology as personal battery-powered wireless dosimeters and permanent built-in area monitors. Plans are also in the works to use the 5 existing units onboard the ISS to monitor the radiation environment in the test of the first inflatable habitat module.
