The radiation environment encountered in space differs in nature from that on Earth, consisting
mostly of highly energetic ions from protons up to iron, resulting in radiation levels far exceeding
the ones present on Earth for occupational radiation workers. Since the beginning of the space
era the radiation exposure during space missions has been monitored with various passive and
active radiation instruments. Also on-board the International Space Station (ISS) a number
of area monitoring devices provide data related to the spatial and temporal variation of the
radiation field in – and outside the ISS. The aim of the DOSIS 3D (2012 - ongoing) experiment
is the measurement of the radiation environment within the European Columbus Laboratory of
the ISS. These measurements are, on the one hand, performed with passive radiation detectors
mounted at eleven locations within Columbus for the determination of the spatial distribution
of the radiation field parameters and, on the other hand, with two active radiation detectors
(DOSTEL) mounted at a fixed position inside Columbus for the determination of the temporal
variation of the radiation field parameters. The talk will give an overview of the current results of the data evaluation performed for the passive and active radiation detectors for DOSIS 3D
in the years 2012 to 2020 and further focus on the work in progress for data comparison with
other passive and active radiation detector systems measuring on-board the ISS
