He also agrees with his boss's complaints. The power of such a laser cannon even takes so long to penetrate the armor layer they designed. Such an attack effect is of no practical significance. It is no wonder they cannot accept this test. It turned out.

"Forget it, I have also tested how the armor layer of the spacecraft 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 is over, we still have to continue to invest more energy in the research and development of laser weapons, otherwise our spacecraft should not only be equipped with electromagnetic railguns, right? Although its attack power is sufficient, the attack speed of the electromagnetic railgun is really too slow.

Moreover, this single attack mode is too easy to be targeted, and it is not a good thing for the safety of our spacecraft's future navigation in the universe! "Come here for a while, Lei Tiantang can only reluctantly accept the test result himself.

"What you said, boss, let's continue with the last extreme violent test. Let's see how much cosmic radiation our spacecraft can withstand!" Kuafu said with a smile.

Although he is not satisfied with the test results, he also knows that this setback is only the longest encounter in technology research and development. Instead of entangled with the test results, it is better to consider the subsequent experiments. The violent test stage is the last one. The content of the test is complete, and he will finish the intense radiation exposure experiment earlier, and he is also good to count the results of the experiment.

Space radiation is a special mixture of 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 landings.

Even if the International Space Station has been operating for many years, its orbit is only 400 kilometers above the earth, and our earth sphere is refracted by the lower atmosphere, and the cosmic rays have already intercepted the most of them before they reach the International Space Station. One third of the dangerous particles are reflected off 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.

During the several moon landings of the United States, because there was no protection of the atmosphere, the radiation received by astronauts in space was even stronger!

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 investigated the lifespan and causes of death of astronauts who landed on the moon in the United States and found that half of their deaths were due to cardiovascular disease, which is about five times higher than that of astronauts in low Earth orbit!

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

Because the largest source of radiation here is just the rays emitted by the stellar remains that exploded a few years ago, the radiation intensity of the stellar system near the body of the small black hole is not large compared to other radiation sources in the universe.

Of course, even if the intensity of this radiation is not high, it does not mean that it is not dangerous. X-rays and ultraviolet rays do not harm the human body at all. In the space environment outside the planetary atmosphere, ultraviolet rays can cause a lot of astronauts. Harmful effects.

For example, the appearance of erythema in the cortex and the dark complexion can also cause diseases such as eye conjunctivitis, iritis, and corneal ulcers. Therefore, astronauts must wear protective clothing and filters before performing extravehicular activities.

In addition, ultraviolet radiation on the thermal control surface and optical devices of long-running space stations will cause performance degradation, and severely cause thermal control to lose balance. Studies have shown that ultraviolet radiation also has a destructive effect on insulating materials, optical materials and polymer materials.

Because solar ultraviolet and extreme ultraviolet radiation have a heating effect on the upper atmosphere, they often lead to an increase in atomic oxygen density and aggravate the erosion of the surface of spacecraft. This hazard also affects their spacecraft.

Not only this radiation threat, but the strong radiation environment in the universe is simply not too much. The neutron radiation from neutron stars, the radiation from strong magnetic stars, and the gamma-ray bursts generated during supernova explosions, etc., 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 penetrating power. It can easily pass through shields, even subatoms that can effectively shield other radiation. It cannot be shielded~lightnovelpub.net~Gamma radiation, as a kind of ionizing radiation, can cause molecular changes. When the DNA of a living body is invaded, it may become cancerous.

The skin cannot stop 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 damage in biology. It is this damage that causes cancer and genetic diseases caused by ionizing radiation.

Nuclear workers generally accumulate large doses of gamma radiation. Research on the bodies of nuclear workers has found that gamma radiation exposure is related to leukemia, lung cancer, liver cancer, bone cancer and other intractable cancers. In addition to radiation, gamma rays can also cause thermal burns and cause suppressive immune effects.

You can't expect all astronauts to become Hulks after being exposed to gamma rays like Dr. Banner did? Or is it lucky to encounter radiation that is beneficial to humans like the Fantastic Four, which leads to genetic evolution?

To be more serious, the radiation that is beneficial to humans in the cosmic environment is pitiful, and even if some radiation has some benefits to the human body, when the intensity of this radiation exceeds the human body’s tolerance, good things will become Bad thing.

Therefore, when navigating in the universe, the defense capability of a spacecraft against all radiation is the most basic requirement for its ability to fly in the universe. No one will go up and die if a spacecraft cannot guarantee the safety of astronauts.

And now Lei Tiantang and Kuafu are going to use a variety of strong radiation irradiation machines they designed to detect the defense capabilities of the spacecraft’s armor layer against these radiations, because the radiation intensity of the experiments they are doing is based on the extreme violence test. Therefore, the radiation intensity generated by the equipment is very high.
