Astronomy Science ~ A recent study revealed that cosmic radiation may be harmful to humans as previously thought, it makes traveling in space is relatively more secure in the future. Analysis of experimental data derived from matroshka, which is the first comprehensive measurement of long-term exposure of astronauts to cosmic radiation, which has now been completed and trials conducted inside and outside the International Space Station.
Among the many life-threatening danger to space tourists, cosmic radiation is one of the main dangers. This severely limits the time to an astronaut in space without causing risk to health due to exposure to high doses of ionizing radiation.
To determine the actual radiation doses received by astronauts in undergoing long-term space travel, the European Space Agency (ESA) in collaboration with research institutes from Germany, Poland, Austria, Sweden and Russia, design and carry out experiments matroshka.
This experiment involves a phantom that mimics the human body is equipped with several thousands of detectors, which are mostly produced in Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) in Krakow, Poland.
The main danger to the health of astronauts due to cosmic exposure radiation is an increased chance of cancer in her body. This possibility is very dependent on the type of radiation on astronauts. Most of the natural sources of ionizing radiation on Earth is produced by high-energy electromagnetic radiation - gamma rays.
On the other hand, energetic protons or heavy ions dominate in cosmic rays, which are far more effective in creating cancer cells. Thermoluminescent detector can not distinguish between gamma rays or ions, therefore Phantom also comes with plastic track detectors tracker protons or heavy ions to be measured.
Experimental results of Matroshka, scientists concluded that astronauts traveling to the moon or Mars may be a bit more secure in terms of radiation than the previous assumption. However, the space tourists continue to receive the radiation, although lower than previously thought, but it still remains very high.
