[Some aspects of the radiation exposure of cosmonauts traversing the Earth’s magnetosphere.]

Aviakosm Ekolog Med. 2021; 55 (3): 51-56. Russian.

To note: Extract from the summary: “The dose load of representative body organs of the cosmonaut beyond the Earth’s magnetosphere was calculated for various scenarios of departure from a reference orbit in space vehicles of different design. Calculation of the contribution to equivalent doses of protons and electrons from Earth’s radiation belts and galactic cosmic rays (GCRs) have demonstrated that, regardless of vehicle design, during solar minimum and increasing activity, the equivalent dose does not exceed the limit established for a single exposure is 150 mSv. However, the radiation exposure can sometimes vary depending on the trajectory of the crossing. “

Aviakosm Ekolog Med. 2021; 55 (3): 57-61. Russian.

To note: Excerpt from the abstract: “Microbiocenosis in the upper respiratory tract and intestine was studied in experienced test subjects who may have possibly adapted to stress in chamber studies lasting 8 at 10 days faster than beginners. The eubiotic index was used to assess positive and negative changes in the microbiota. The gut microflora in experienced subjects was found to be more plastic and adapted much faster compared to to inexperienced counterparts. In both groups, the composition of the microbiota was slightly compromised at the end of the acute adaptation and then stabilized. “
