Paramecia cultures placed at 3800 meter altitude, show a proliferating activity acceleration if we compared them to control cultures placed at low altitude under the same environment conditions. These results confirm the cosmic irradiation influence upon the activating effect produced by the natural ionizing radiations on living organisms.

Exposure to ionizing radiation during manned deep space missions to Mars could lead to functional impairments of the central nervous system, which may compromise the success of the mission and affect the quality of life for returning astronauts. Along with radiation-induced changes in cognitive abilities and emotional status, the effects of increased motor activity were observed. The mechanisms behind these phenomena still remain unresolved.

One of the most problematic goals for radiation safety during spaceflight is an assessment of additional doses received by astronauts during extravehicular activity (EVA). The Pille-ISS thermoluminescent dosimeter developed by the predecessor of the Hungarian Research Network (HUN-REN) Centre for Energy Research (Budapest, Hungary) is designed for the routine dose measurements not only inside the spacecraft compartments, but also for personal dosimetric control for EVA. During almost two decades of the International Space Station (ISS) operation, the unique set of 131 EVA doses were recorded in different conditions, such as: solar activity, ISS trajectory along the South Atlantic Anomaly (SAA), and shielding conditions provided by two kinds of spacesuits: the Extravehicular Mobility Unit (EMU) and Orlan.

Future long duration space missions will expose astronauts to higher doses of galactic cosmic radiation (GCR) than those experienced on the international space station. Recent studies have demonstrated astronauts may be at risk for cardiovascular complications due to increased radiation exposure and fluid shift from microgravity. However, there is a lack of direct evidence on how the cardiovascular system is affected by GCR and microgravity since no astronauts have been exposed to exploratory mission relevant GCR doses.

Space missions have revealed certain disincentive factors of this unique environment, such as microgravity, cosmic radiation, etc., as the aerospace industry has made substantial progress in exploring deep space and its impacts on human body. Galactic cosmic radiation (GCR), a form of ionizing radiation, is one of those environmental factors that has potential health implications and, as a result, may limit the duration - and possibly the occurrence - of deep-space missions.

The BioSentinel CubeSat was deployed on the Artemis-I mission in November 2022 and has been continuously transmitting physical measurements of the space radiation environment since that time. Just before mission launch, we published computational model predictions of the galactic cosmic ray exposure expected inside BioSentinel for multiple locations and configurations. The predictions utilized models for the ambient galactic cosmic ray environment, radiation physics and transport, and BioSentinel geometry.
