New methods to characterize radiation in the ATLAS experiment have been developed using Timepix detectors. Measurements of total ionizing dose and charged particle fluences at different locations in the experiment are used to benchmark Geant4 simulations.

We present a unified framework, to consolidate both data and methodologies, perform comparisons under the same constraints, and produce trapped particle radiation models that can be tailored to any future user's use-case scenarios.

Using correlation between LEO and equatorial electron measurements, a methodology is presented and validated, with the ICARE-NG detector measurements on board EUTELSAT 7C to infer flux encountered by the spacecraft during its EOR phase.

We investigate pitch angle distributions in the inner radiation belt in equatorial regions. We use data from IREM (INTEGRAL mission) and PROTEL (CRRESmission). We find a dependency of flux anisotropies on the proton energy levels.

This study addresses the association of solar wind conditions, geomagnetic parameters, wave activity, and seed electrons, and indicates that seed electron presence, plasmasphere erosion and wave activity are conditions leading to substantial relativistic electron enhancements.

Initial conclusions of a feasibility study for a low-cost, short-duration mission to measure the space environment whilst simultaneously measuring effects on components, testing mitigation strategies and giving flight heritage to new detectors and components.
