Abstract

The paper presents measurement data obtained in the Shielding Composite space experiment by thermoluminescent and solid-state track detectors. A cylindrical container made of a composite shielding material based on fluoroplastic (1 cm thick, density 4.05 g/cm3) was installed in the left cabin of the International Space Station (ISS) Service Module. The measurement data were obtained for the period from February 21 to September 19, 2022, which falls at the growth phase of the solar activity cycle. The shielding effect of the composite material was determined as the ratio of doses received outside and inside the container, and according to measured data, it was 1.33 ± 0.08 for the absorbed dose and 1.29 ± 0.07 for the dose equivalent. This effect is mainly due to a decrease in the contribution to the dose from the Earth’s radiation belts, which corresponds to the results of calculations carried out by the ray tracing method for the detector locations.
