on the ISS dose of radiation in compartments, where the cosmonauts sleep, 30-40 percent above indicators in other parts of the station. About this “Izvestia” told the head of the laboratory of methods and means of supporting radiation safety in space flights ISBP RAS Vyacheslav Shurshakov.
He explained that “the cabin is adjacent to his facet to the side surface of the cylinder from a thin aluminum sheet forming the outer surface of the station, and the astronaut sleeps right around the wall.” This flaw was allowed during the design of the station, then the protection against radiation did not give enough attention.
On April 18, Vice Prime Minister Yuri Borisov said that Russia in 2025 will be released from the project of the International Space Station (ISS) and will begin to create a new national orbital station. Shurshakov called on the designers in advance to provide protection of people from irradiation and indicated that water and polyethylene, slow-charged particles and neutrons, are best used as a protective material.
In 2020, Shurshakov said that tourists who will go on the Crew Dragon ship Ilona Mask to a record height of 1000 kilometers will receive a dose of radiation close to a permissible accident in Chernobyl liquidators. According to him, the dose will be 150 millizivers or one six permissible dose, and in five days, they will irradiate as astronauts on the ISS for 250 days. The permissible annual dose in the liquidators of accidents at the NPP is 200 millisyver.
Earlier in Roskosmos, they proposed to abandon the International Space Station due to the high cost. In the state corporation, they calculated that after 2025 avalanche-like failure of the ISS systems will begin, as a result of which further maintenance of the station will cost 10-15 billion rubles.
