Two Silicon‐detector based DOSimetry TELescopes (DOSTELs) have been measuring the cosmic
radiation in the COLUMBUS module of the International Space Station since 2009 and have now
recorded data over more than one solar cycle covering the maxima of galactic cosmic ray intensity in
2009 and 2020 and the intensity minimum in between. Dose rates in the ISS orbit from galactic cosmic
radiation and trapped particles from the radiation belt in the South Atlantic Anomaly over this time
are presented. The variation of dose rates over the solar cycle and the dependency on the geomagnetic
shielding quantified by the cut‐off rigidity are investigated. Using dose rates measured at low
geomagnetic shielding and correcting for the altitude dependent shielding from Earth against cosmic
radiation, the expected dose and dose equivalent rates from galactic cosmic radiation in near‐Earth
interplanetary space are derived.
In addition to the data as measured with the DOSTEL instruments a short update for the data as
measured with the passive radiation detectors in the frame of the DOSIS and DOSIS 3D projects will be
provided as well
