The main goal of UTBI is the measurement of the background radiation inside spacecraft. Measurements of the X-ray, gamma ray and other particles (protons, neutrons, electrons) have a very important effect outside the Earth's geomagnetic field, which can help in the development of future space vehicles and other space technologies.Principal Investigator(s)

During the UTBI (Under The Background Influence) experiment, the background radiation is measured inside the modules of the International Space Station using a new type of radiation sensor. Radiation models, that predict these radiation levels, will be verified and, if necessary, corrected with the experimental data.
The new type of sensor that measures the radiation is made of an alloy of Cadmium, Zinc and Tellurium. The advantage of this specific detector is that it is compact and does not require cryogenic cooling. The UTBI experiment will demonstrate this specific sensor technology for the first time in space and possibly act as a precursor for an instrument of ESA's Atmospheric-Space Interaction Monitor (ASIM), which is planned to be accommodated on an external payload adapter on the outside surface of the European Columbus laboratory once it is launched to the ISS.
Radiation can have severe health consequences for crewmembers. Understanding radiation, its interaction with the ISS and its impact on the human body shall therefore be considered as an important factor that has to be taken into account for longer duration flights around the Earth as well as flights and stays towards and on the Moon and Mars.
