Dose Distribution Inside ISS - Dosimetry for Biological Experiments in Space (DOSIS-DOBIES) - 11.22.16
The Dose Distribution Inside ISS - Dosimetry for Biological Experiments in Space (DOSIS-DOBIES) provides documentation of the actual nature and distribution of the radiation field inside the ISS and develops a standard method to measure the absorbed doses in biological samples onboard the ISS. Science Results for Everyone
I’ll see your radiation dose and double it. Two active and two passive radiation detectors collected data from different locations in the space station. Data from the passive detectors were analyzed on the ground while monthly downlinks collected data from the active detectors. The passive thermoluminescence detectors (TLD) yielded data on daily dose rate measured with both neutron sensitive 6LiF and non-neutron sensitive 7LiF. The data showed that the absorbed dose rate inside the Columbus module can vary up to 50 percent depending on location. Experiment Details

ISS Expedition Duration
April 2009 - September 2011
DOSIS-DOBIES first began operations on ISS Expedition 18.
- DOSIS will use both passive and active radiation measurement devices to measure the radiation environment inside of the Columbus module.
- DOBIES will study the responses of different detector types in space radiation fields. This will lead to a unique recommendation and description on dosimetric systems for radiobiologocal experiments in space.
- A total number of 64 measurement positions are allocated to the DOSIS-DOBIES investigations.
Dose Distribution inside ISS (DOSIS): The proposed experiment will provide documentation of the actual nature and distribution of the radiation field inside the spacecraft. 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.
Dosimetry for Biological Experiments in Space (DOBIES): The objective of this project is to develop a standard Dosimetric method (as a combination of different techniques) to measure the absorbed doses and equivalent doses in biological samples, as a contribution to DOSIS in EPM and COL, and EXPOSE-E and EXPOSE-R payloads.
Operational Requirements and Protocols
DOSIS-DOBIES will consist of active radiation detectors: two DOSTEL silicon detectors, Alteino, tissue equivalent proportional counter (TEPC), Pille thermoluminescent detector (TLD) reader, passive radiation monitoring instruments and nuclear track detector packages (NTDP).
