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.

Description

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.

Applications

Space Applications

A complete understanding of the space radiation environment and the potential radiation doses that crewmembers receive allows investigators to obtain the data necessary to issue recommendations for space radiation protection.

Earth Applications

This experiment enlightens scientists more concerning the use of devices for data collection and how to monitor real-time data. This could prove beneficial to radiation monitoring of commercial airline crews and military flight crews.

Operations

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.
