What are the health effects of cosmic rays on the human body?
Space rays are energy particles (in fact not rays) that quickly pass through the universe. They are everywhere and every second several tens will slam into your body. These cosmic rays are too low -energy to cause any serious health effects, except for several genetic mutations and space rays are in fact one of the drivers of evolution. Your body receives about 2.4 msv (millisievrti) radiation caused by the effects of space rays every year. For comparison, it takes about 1 sienerto radiation in a short time to cause nausea, and about 2-6 sieves cause death. For this reason, people who spend a lot of time at high altitudes, such as airline pilots, flight attendants and air test pilots, are experiencing dozens of cosmic rays that people do on Earth. It is still deeply unable to career 1-4 SV career recommended the National Council for Radiation Protection and Measurement. The flow of the cosmic beam is low enough in the Earth's atmosphere that the exposition withIt becomes a problem in space.
on the International Space Station, 350 km (217 miles) above the Earth's surface, astronauts experience the effects of space rays a hundred times more numerous than those experienced by people on Earth. The Earth's atmosphere is such an effective isorator that barely any particles really get to the ground, and most of what people are exposed to is secondary radiation from precipitation in the upper atmosphere. At the cosmic stations, astronauts are exposed to primary radiation. However, people spent more than a year in space without the poor effects of space rays and seem to be possible for indefinite long stays.
People who would be the most exposed Cosmic Rays are people who travel between Earth and Moon or Earth and other planets. The Earth is primarily protected by its magnetosphere, a huge magnetic field that extends about 70,000 km (43,500 miles) from the Earth's surface in all directions. LetE magnetosphere and you are exposed to galactic cosmic rays - one of the strongest types - which are usually blocked by the magnetic shielding of the Earth. In accordance with this, Astronauts Apollo said they had seen flashes of light in their eyeballs, which could have been galactic space rays. The effects of the prolonged exposure to these rays - say, on a mission on Mars - are not known.
