It is important to assess the radiation level inside the human brain to evaluate the possible hazardous effects on the central nervous system especially during solar energetic particle (SEP) events. We use a realistic model of the head/brain structure and calculate the radiation deposit therein by realistic SEP events, also under various shielding scenarios. We then determine the relation between the radiation dose deposited in different parts of the brain and the properties of the SEP events and obtain some simple and ready-to-use functions which can be used to quickly and reliably forecast the event dose in the brain. Such a novel tool can be used from fast nowcasting of the consequences of SEP events to optimization of shielding systems and other mitigation strategies of astronauts in space. 4950 https://doi.org/10.1038/s41598-021-90695-5$xR$3Volltext$534 4950 https://nbn-resolving.org/urn:nbn:de:gbv:8:3-2022-00282-4$xR$3Volltext$534 4961 https://macau.uni-kiel.de/receive/macau_mods_00002695 5051 600 5051 610 5051 620 5550 Brain 5550 Central Nervous System 5550 Exobiology 5550 Humans 5550 Radiation Protection 5550 Risk Factors 5550 Solar Energy 5550 Space Flight
