I have a little black hole

Chapter 856 The last violence test-strong radiation exposure test!

He also agrees with his boss’s vomiting. The power of such a laser cannon can only be penetrated by the armor layer designed by themselves for such a long time. Such an attack effect has no practical significance at all. No wonder they cannot accept this test. It turned out.

"Forget it, anyway, we have also tested how the spacecraft armor layer we designed performs under the attack of laser weapons, and the relevant test data cannot be said to be useless at all!

After this test, we should continue to invest more energy in the research and development of laser weapons, otherwise we will not be able to install only the electromagnetic rail gun as a weapon in our spacecraft?Although its attack power is sufficient, the attack speed of the electromagnetic rail gun is too slow.

And this single attack mode is too easy to be targeted, which is not a good thing for the safety of our spaceship's future navigation in the universe!"After a while, Lei Tiantang could only barely accept the test results himself.

"Boss what you said is the same, then continue to the last extreme violence test, let's see how strong the cosmic radiation our designed spacecraft can withstand!" Kuafu said with a smile.

Although he is not satisfied with such test results, he also knows that this kind of setback is only the longest encountered situation in scientific research and development. Rather than entangle this test result, it is better to consider the following experiments, the violent test stage is the last one The content of the test is complete. He completed the strong radiation exposure experiment earlier, and he also statistics the experimental results.

Space radiation is a special mixture containing gamma rays, high-energy protons and cosmic rays.So far, human astronauts have basically never experienced a full dose of space radiation except for a limited number of moon landing activities.

Even the International Space Station, which has been in operation for many years, because its orbit is only 400 kilometers above the earth, and our Earth sphere through the refraction of the lower atmosphere, has intercepted the most of them before the cosmic rays reach the International Space Station. One third of the dangerous particles are reflected by the earth's magnetic field.

In this case, only a small part of the cosmic rays hit the astronauts, so the actual danger of space radiation is far from what can be estimated in the laboratory.

In Lao Mei’s lunar landings, astronauts received more radiation in space because of the lack of atmospheric protection!

Even if the outermost layer of the spacesuit is made of white aluminum-plated fabric, it can effectively reduce the harm of radiation and cosmic rays to the human body, but it is not completely blocked!

Scientists have investigated the lifespan and causes of death of astronauts on the moon and the old and found that half of their deaths are due to cardiovascular diseases, and this is about 5 times higher than the probability of astronauts in low-Earth orbit!

Although Lei Tiantang’s spacecraft had exposed the spacecraft directly to cosmic rays in previous flight tests and collected relevant data, this data is also very thin because the small black hole near the body The cosmic environment is quite peaceful.

Because the largest radiation source here is just the rays emitted by the debris of the star that exploded a few years ago, the radiation intensity of the star system near the body of the small black hole is not much greater than the radiation intensity of other radiation sources in the universe.

Of course, even if the radiation intensity is not large, it does not mean that it is not dangerous. The damage of X-rays and ultraviolet rays to the human body is not small. In the space environment outside the planetary atmosphere, ultraviolet rays will produce a lot of astronauts. Harmful effects.

For example, erythema appears in the cortex and the skin color becomes dark. It can also cause diseases such as conjunctivitis, iritis and corneal ulcers.Therefore, astronauts must wear protective clothing and filters before carrying out extravehicular activities.

In addition, long-term operation of the thermal control surface and optical devices of the space station will cause performance degradation due to ultraviolet radiation, which will seriously cause the thermal control to lose its balance. Studies have shown that ultraviolet radiation can also damage insulating materials, optical materials and polymer materials.

Because solar ultraviolet and extreme ultraviolet radiation have a heating effect on the upper atmosphere, it often leads to increased atomic oxygen density and exacerbates the erosion of the spacecraft surface. This hazard also affects their spacecraft.

Not only is this radiation threat, the strong radiation environment in the universe is not too much, the neutron radiation of the neutron star, the radiation of the strong magnetism star, and the gamma ray burst produced by the supernova explosion will all affect the spacecraft. Astronauts pose a deadly threat.

Of all the radiation, gamma radiation is the most dangerous, because it has the shortest wavelength on the electromagnetic spectrum and the strongest penetration, and it can easily pass through the shield, even the subatoms that can effectively shield other radiation. It cannot be blocked.Gamma radiation, as an ionizing radiation, can cause molecular changes. When the DNA of a living body is attacked, cancer may occur.

The skin cannot prevent gamma rays, and once the genetic material of the cell is disturbed, it may induce DNA dislocation.DNA double helix strand breaks are generally regarded as the most serious biological damage. It is caused by ionizing radiation that causes cancer and genetic diseases.

Nuclear workers generally have accumulated large doses of gamma radiation. Studies of nuclear workers have found that gamma radiation exposure is associated with leukemia, lung cancer, liver cancer, bone cancer, and other intractable cancers.In addition to radiation, gamma rays can also cause thermal burns and cause inhibitory immune effects.

You can't expect all astronauts to turn into Hulk after being exposed to gamma rays like Dr. Banner?Or is it as lucky as the Fantastic Four to encounter genetically evolved radiation that benefits humans?

To put it more seriously, the radiation that is beneficial to humans in the cosmic environment is pitiful, even if some radiation has some benefits for the human body, but when the intensity of this radiation exceeds the tolerance of the human body, good things will become Bad thing.

Therefore, when navigating in the universe, the spacecraft's ability to defend against all radiation is the minimum requirement for its ability to ride the universe. No one can guarantee the safety of astronauts.

And now the test that Lei Tiantang and Kuafu want to do is to use various strong radiation irradiation machines designed by them to detect the defense ability of the spacecraft's armor layer against these radiations, because the radiation intensity they want to do is based on the extreme violence test. The requirements come from, so the radiation intensity generated by the equipment is very high.
