The radiation environment over the African continent, at aviation altitudes,
remains mostly uncharacterized and unregulated. In this paper we present
initial measurements made by a newly developed active dosimeter on-board
long-haul flights between South Africa and Germany. Based on these initial
tests, we believe that this low-cost and open-source dosimeter is suitable for
continued operation over the Africa continent and can provide valuable
long-term measurements to test dosimteric models and inform aviation policyComment: Accepted to appear in Journal of Space Weather and Space Climat
