Expert Vyacheslav Shurshakov, head of the Department of radiation safety of manned space flight Institute of biomedical problems, Russian Academy of Sciences, compared the dose of radiation that will be received by the space travelers during a flight aboard the Crew Dragon, the dose received by the liquidators of the Chernobyl accident.
He said that during the five days of flight, Space Adventures customers will receive a dose of 150 millisieverts (this is one-sixth the dose of radiation, valid for life). The liquidators of the Chernobyl accident for the year received 200 millisieverts, according to RIA Novosti.
the expert Also compared the exposure of tourists and astronauts to the ISS. Due to the fact that Crew Dragon, rising to a record 1,000 kilometres, will pass Earth radiation belts, the passengers will get a dose 50 times higher than the dose of the participants of the expeditions on the International space station. For five days in orbit they are exposed to as well as the crews of the ISS are exposed for 250 days. The tourists will get radiation “according to the bought tickets,” said Shurshakov.
According to the agreement with SpaceX, in 2021 or 2022 on the spacecraft Crew Dragon will be sent four tourists. Previously Space Adventures has sent tourists into outer space on the Russian Soyuz. However, in June 2019, the operator began to collect applications from those who wanted to go up to the ISS with the help of the ship’s Cockpit, developed by Boeing.
