Priority is protect the health of astronauts. They wanted to know if the damage that radiation could do to astronauts could be detected. In addition, they also wanted to check if there were differences depending on gender, age and other factors.

Radiation hazard

Cosmic radiation born of three things: particles captured by our planet’s magnetic field, particles ejected into space during solar flares, and galactic cosmic rays. The latter take place outside the solar system.


Exposure to radiation can cause very serious illnesses such as like cancer or cardiovascular problems. Fortunately, on our planet we are protected from this thanks to both the earth’s magnetic field and the atmosphere.

NASA conducts research into potential medical countermeasures, such as the use of pharmaceuticals or early disease detection technologies, to help mitigate the consequences radiation exposure from space.

However, for missions beyond the orbit of our planet , the same level of protection against armor cannot be granted or the exposure time of the mission may be limited.

This is why NASA is looking for ways to prepare astronauts so they can carry out longer missions safely.

With age, people their chromosomes change. It can happen naturally or through environmental influences … Chromosomes contain essential components of our DNA, and altering them can be very harmful to health.

A study was conducted to test the exposure to radiation.

The International Space Station conducted exploration with 43 astronauts to see if they were affected by the radiation before and after the mission. To do this, a blood sample was taken before the mission and their blood cells were tested to assess their official chromosomal status and see how it might change in the future.

After that, the specimens were deliberately exposed. to gamma rays on Earth to measure how easily their cells accumulate chromosomal changes.

So when the astronauts returned after completing the space mission, they had a new blood sample taken to check for changes in chromosomes.

Samples before and after the mission began to compare and several things were discovered.

People with more sensitivity were more likely to have chromosomal changes than those with low sensitivity. On the other hand, people who had more changes in chromosomes with tests that were done before the flight were the most receptive go through modifications in them.

In addition, they also believe that if missions to space are to be completed, it is they are best done for older people, as young people are more susceptible to long term diseases from radiation exposure than in the elderly, although both have sensitivity to radiation. radiation. This is because young people live longer and can live long enough to develop cancer or other medical conditions.

Hence it it is important to develop technology which allows you to know the radiation levels when performing a space mission, as this is vital for health of astronauts.
