Chapter 856

Make complaints about his own boss's Tucao, and the power of such a laser cannon is so long that the armor layer he designed himself can not be broken for such a long time. This kind of attack is of no practical significance. No wonder they can't accept the test result.

"Well, at least we have tested how the armor layer of our spaceship has behaved under the attack of laser weapons. The relevant test data can't be said to be useless at all!

After this test, we still need to continue to invest more energy in the development of laser weapons, or we can't only install electromagnetic railguns on our spaceships then? Although its attack power is enough, but the electromagnetic railgun's attack speed is really too slow.

Moreover, this single attack mode is too easy to be targeted, which is not a good thing for the safety of our spacecraft in the space in the future Over for a while, Lei Tiantang can only reluctantly accept the test results.

"Boss, that's what you said. Let's go on with the last extreme violence test. Let's see how much radiation our spacecraft can withstand." Kuafu said with a smile.

Although he is not satisfied with such test results, he also knows that this setback is only the longest encountered in scientific and technological research and development. Instead of tangled with the test results, it is better to consider the later experiments. There is only one test item left in the violent test stage. If we finish this strong radiation exposure experiment earlier, he can count the experimental results.

Space radiation is a special mixture of gamma rays, high-energy protons and cosmic rays. Up to now, human astronauts have never experienced a full dose of space radiation except for a few limited moon landing activities.

Even the long-term operation of the international space station, because its orbit is only 400 kilometers above the earth, and our earth sphere through the refraction of the lower atmosphere, before cosmic rays reach the international space station, has intercepted one third of the most dangerous particles, and another third is reflected by the earth's magnetic field.

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

But in those lunar landing activities of the United States, because there is no protection of the atmosphere, the radiation of astronauts in space is also stronger!

Even if the outermost layer of the spacesuit is made of white aluminized fabric, which can effectively reduce the harm of radiation and cosmic rays to human body, it is not completely barrier!

Scientists have investigated the life span and causes of death of the US astronauts on the moon, and found that half of their deaths are due to cardiovascular diseases, which is about five times higher than that of astronauts in low earth orbit!

Although Lei Tiantang's spaceship has exposed the spacecraft to cosmic rays in previous flight tests, and has collected relevant data, this data is also very thin, because the space environment around the small black hole itself is quite peaceful.

Because the biggest radiation source here is just the radiation from the star wreck that exploded several years ago. The radiation intensity of the star system near the small black hole body is not large compared with other radiation sources in the universe.

Of course, even if the radiation intensity is not large, it does not mean that there is no danger. X-ray and ultraviolet ray damage to the human body is not small at all. In the space environment outside the planetary atmosphere, ultraviolet radiation will have many harmful effects on astronauts.

For example, the cortex appears erythema, skin color becomes dark, can also cause eye conjunctivitis, iritis and corneal ulcer and other diseases. Therefore, astronauts must wear protective clothing and filters in advance.

In addition, ultraviolet radiation on the thermal control surface and optical devices of the long-term operation of the space station will cause performance degradation, and seriously make the thermal control out of balance.

Due to the heating effect of solar ultraviolet radiation and extreme ultraviolet radiation on the upper atmosphere, it often leads to the increase of atomic oxygen density, which aggravates the denudation of spacecraft surface, which also affects their spacecraft.

Not only is this radiation threat, but the strong radiation environment in the universe is not too much. The neutron radiation of neutron star, the radiation of strong magnetic star, and the gamma ray burst produced by supernova explosion will cause fatal threat to the astronauts in spaceships.

Among all the radiation, gamma radiation is the most dangerous, because it has the shortest wavelength in the electromagnetic spectrum and the strongest penetration. It is easy to pass through the shield, and even the subatomic which can effectively shield other radiation can not shield it. As a kind of ionizing radiation, gamma radiation can cause molecular changes. When the DNA of a living body is invaded, cancer may occur.

The skin can't block 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, which is caused by ionizing radiation carcinogenesis and genetic diseases.

A large dose of gamma radiation is generally accumulated on the body of nuclear workers. The study on the body of nuclear workers shows that gamma radiation exposure is related to leukemia, lung cancer, liver cancer, bone cancer and other stubborn cancers. In addition to radiation, gamma rays can also cause thermal burns and cause inhibitory immune effects.You can't expect all the astronauts to turn into hulks after being exposed to gamma rays like Dr. Benner? Or are you lucky enough to encounter radiation that is beneficial to human beings and generate genetic evolution?

To put it more seriously, there is very little radiation beneficial to human beings in the cosmic environment. Even if some radiation is beneficial to human body, when the intensity of radiation exceeds the tolerance of human body, good things will become bad.

Therefore, in the space navigation, the spacecraft's ability to defend against all radiation is the minimum requirement for whether it can gallop the universe. No one will go up to die if the spaceship can not guarantee the safety of astronauts.

Now, the test that Lei Tiantang and Kuafu want to do is to use all kinds of strong radiation irradiation machines designed by them to test the defense ability of the spacecraft's armor layer against these radiation. Because the radiation intensity they want to do is in accordance with the requirements of extreme violence test, the radiation intensity generated by the equipment is very high.
