DOSIS 3D – current status and science updated

Abstract

The radiation environment inside the Columbus Laboratory of the ISS has been measured with active and passive radiation detectors within the frame of the DOSIS (2009 – 2011) and the DOSIS 3D (2012 -) project. Two active Dosimetry Telescopes (DOSTEL) have been mounted at a fixed position beneath the EPM rack in Columbus to enable the long-term measurements of relevant radiation field parameters (dose) and to determine solar cycle variations of the GCR and SAA contributions inside Columbus. Data has been compared with various other active radiation detectors on board the ISS, Moon and Mars. With the eleven passive radiation detector packages (PDPs) placed in Columbus the relevant dose values for six months’ time periods have been determined for up to now 26 ISS missions. The talk will give an overview of the current status of DOSIS 3D and the planned future activities.
