Future Martian colonists are in danger of death from cancer

As one of the instruments aboard the Curiosity Rover installed detector of radiation load, which measures the dose of radiation received by the apparatus. Only during the flight from Earth to Mars aboard spacecraft, it was 1.8 millisieverts per day. Safe is normal for a person considered to be 10 microsieverts, and 1 sievert threshold, after which the good health of the astronaut is no guarantee.

The likelihood of notoriously deadly cancer while receiving radiation on the intact, full-length SV is 5.5 %. Plus there are other negative factors that future colonists will face after 500 days of its mission. On the surface of Mars fonit not as much to 0.67 of milizivert in the day, but this only doubles, triples maximum safe period allotted to man. Model the job to fly there and back, lasting 900 days – that’s all that is available to us.

Data from Curiosity resonate with research on the ISS, where he calculated the safe time limit of staying in space as 18 months for females and 24 months for men. In the suit in the black abyss that in the capsule of the ship – alas, but “heavy” rays from the depths of the galaxy, such protection does not help in any way. What’s worse, not even affected by the radiation of the cells in the human body also begin to mutate – like the spoilt neighbours.

The current standard from NASA describes the probability of cancer for people in low earth orbit as 3 %. For those who will go further into space, it will inevitably strive for 100 %. The solution is simple – to create, to invent such technologies and materials that would become the most effective protection against radiation in the Universe. Pretentious wording chosen on purpose, as existing methods are objectively useless for such tasks. We, mankind, needed scientific and technological breakthrough if we want to go at least to Mars.
