ISS Science for Everyone

Science Objectives for Everyone
The TRITEL investigation characterizes the radiation environment within the Columbus module of the International Space Station (ISS) with high accuracy. It uses a combination of three different detector types – 3 Silicon Detector Telescopes, ThermoLuminescent and Solid State Nuclear Track Detectors – measuring the radiation amount, direction and history to determine, amongst others, two very important values to humans (absorbed dose and dose equivalent) from solar and galactic radiation. Continued characterization and understanding of the space radiation environment allows researchers to better protect humans during space flight and provides data for improving shielding properties of future spacecraft designs.

    Experiment Description

    Research Overview

    • The goal of the TriTel study includes obtaining temporal information (radiation history) in order to describe the radiation environment in the Columbus module.

    • Specifically, information will be collected regarding the dose equivalent rate, the occurrence of solar particle events (SPEs), the contributions from galactic radiation and solar radiation, and the improved estimation of the dose equivalent of the space flight crew.

    Space Applications

    It is vital for us to understand and monitor the radiation environment around our planet in order to safeguard our astronauts during their missions now, and plan appropriately for their missions in the future. This includes monitoring radiation levels both inside and outside the ISS with different devices, which in turn helps to determine the shielding effectiveness of the ISS in different parts of the Station. This research could also impact, and help in the planning and development of equipment and systems for future human exploration missions outside of low-Earth orbit.

    Earth Applications

    This research can help to better understand Earth’s radiation ‘weather’ surrounding our planet and whether this has an impact on climatology, and thus help to improve climate models. This research can also feed into applications in high-end technology and health care. The technology could for example be developed into a robotic measuring device in close vicinity of radiation sources on Earth, to scan the radiation environment in three dimensions, with time resolution.
