ISS Science for Everyone

Science Objectives for Everyone
International Space Station crewmembers are continually exposed to varying levels of radiation which can be harmful to their health. Dose Distribution Inside the International Space Station - 3D (DOSIS-3D) uses several active and passive detectors to determine the radiation doses inside the ISS. The goal is a three-dimensional radiation map covering all sections of the ISS.

    Experiment Description

    Research Overview

    • Dose Distribution Inside the International Space Station - 3D (DOSIS-3D) determines the radiation field parameters absorbed dose and dose equivalent inside the ISS with various active and passive radiation detector devices, aiming for a concise three dimensional dose distribution (3D) map of all the segments of the ISS.

    • This is achieved by applying and combining data from passive radiation detector systems consisting of thermoluminescence (TLD-involves the release of previously absorbed radiation upon being heated) and passive nuclear track detectors (PNTD) able to provide absorbed dose, LET (Linear Energy Transfer-a measure of energy transferred to a material as an ionizing particle travels through it) spectra and dose equivalent information.

    The DOSIS-3D experiment will provide documentation of the actual nature and distribution of the radiation field inside the ISS. Integral measurements of energy, charge and LET spectra of the heavy ion component will be done by the use of different nuclear track detectors. TLDs deliver mission averaged absorbed doses. Different neutron dosimeters allow for measurement of the neutron dose.

    Space Applications
    The experiment will pinpoint the distribution and levels of radiation inside the space station. Nuclear track detectors will measure the energy and charge of heavy ions, while neutron dosimeters will track exposure to free neutrons. Thermoluminescent dosimeters, or TLDs, will track the average radiation dose absorbed throughout a mission. A comprehensive understanding of the space radiation environment will allow scientists to issue recommendations for space radiation protection.

    Earth Applications
    Flight crews and nuclear plant workers are also exposed to greater-than-average radiation. The DOSIS-3D experiment provides insight into combining different devices for dosage monitoring, and provides lessons in how to monitor real-time data. This could prove beneficial to radiation monitoring for commercial and military airline crews, as well as other workers exposed to radiation.

    Operational Requirements
    DOSIS-3D requires continuous monitoring of the ISS radiation environment, making use of various instruments provided by ESA, JAXA, NASA and Russia. Concerning ESA, continuous power for the DOSIS/DOSTEL units, and regular monthly data downlink via EPM is required. Deployment and retrieval of the passive PDP dosimeters at the beginning and at the end of the increments, respectively is also required.

    Operational Protocols
    DOSIS-3D shall be performed for a total of 4-6 increments. The passive dosimeters shall not be exposed to X-rays during ground transportation.
