Radiation characteristics in the spherical tissue-equivalent phantom on the ISS during solar activity minimum according to the data from Liulin-5 experiment

► Liulin-5 measured radiation characteristics in the spherical phantom on ISS during solar cycle 23 minimum. ► Dose rates at 40-60 mm phantom's depth are 7.75-9.6 μGy/h, dose equivalent rates are 24.6-36.7 μSv/h. ► Usually SAA protons contribute ∼60% of the total absorbed dose at 40 mm and ∼40% at 165 mm phantom's depth. ► Shuttle docking and ISS attitude change by 180° cause decrease in dose rates in SAA. ► A detailed mapping of the particle flux distribution along the ISS orbit is done.
