"Boss, you're here. Su Jing went to the Tianci Materials Research Institute and went directly to a laboratory on the second floor, Jiang Ji inside saw him and immediately greeted him warmly, and several other young people also respectfully called the boss. Jiang Ji was full of red face, his eyes were attentive, and he was in a good mood. Because of some of the materials that Su Jing took some time ago, the research during this period of time can be said to have made considerable progress, and what has been produced and operated in cooperation with others is bra materials. Don't underestimate this little bra material, if it sells well, it is likely to bring good profits to the institute.

"How's the research going during this time?" Su Jing asked casually.

"The alloy material you brought, we have fully mastered the composition and proportion of it, and have successfully synthesized it, although the quality is slightly lacking, but compared with the current domestic materials, the properties are still much more advanced. If you produce and sell, you should be able to make a high profit. Jiang Ji said.

"That's good. Su Jing nodded, in fact, when all the materials were brought over, Su Jing did not take them as they were, but only took a small part, so Jiang Ji didn't know that the alloy material in his mouth was actually just a plate from the time and space of the Star Emperor. If he knew that someone used this metal material that is ahead of the country or even the world, but it was actually just a broken plate that had been used by people, he didn't know what he would think. Jiang Ji can synthesize this metal, that is, relying on this plate, it doesn't mean how powerful he is, after all, the difficulty of copying and originality is very different.

"Also, the body armor you want is also ready. Jiang Ji said, took out a body armor and handed it to Su Jing.

"Have you tried it, how is the defense?" Su Jing's eyes lit up slightly, took the body armor, and found that it was not heavy. It's just a little heavier than an ordinary padded jacket, and it's white, smooth and shiny, and it looks like it's made of silver thread.

"Hehe, you'll find out if you try. Jiang Ji smiled.

"Let's go back and try again, I have something here. I need you to help me test what it is. This can be poisonous, so you have to be careful when you test it. Su Jing pointed to the sealed bucket that was placed on the ground.

"Since it may be a poisonous object, it can't be left like this, I'll test it right away. Jiang Ji took two assistants here and began to start testing, while Su Jing sat on the side and waited, not long after. Jiang Ji walked back, his expression a little solemn.

"What, it's really poisonous?" asked Su Jing.

"It's really toxic, carbon monoxide, sulfur dioxide, mercury and other harmful substances, but these are not the biggest problems, the biggest problem is nuclear radiation, I probably tested it, and the radiation dose rate is about 1 microsievert per hour. Jiang Ji said.

"Is this radiation a big deal?" Su Jing frowned. I don't know what kind of garbage in the world actually has nuclear radiation. Fortunately, the test was brought, otherwise it would have caused unimaginable consequences. However, not much is known about nuclear radiation Su Jing, and it is not clear what 1 microsievert per hour means.

"Of course this radiation is big, Xiaobin, you explain to the boss. Jiang Ji said. Turning his head to look at the young assistant next to him.

"Ahem. The young man coughed slightly, and then said, "Boss, I'll use data to speak." The International Basic Safety Standards set a limit of 1 millisievert (1,000 microsieverts) per year for individual exposures to the general public. People who do not come into contact with radioactive substances in their daily work. The normal annual intake of radiation due to the environment (such as radon and other radioactive materials in the air and decoration stone materials) is 1~2 millisieverts per year. Any person who ingests more than 6 millisieverts of radioactive material per year shall be classified as a worker with radioactive material. The dose limit for individuals exposed to occupational exposure is 20 mSieverts per year. Brick house 0 per year. 75 mSievert cosmic rays per year 0. 45 mSieverts, water, grain, vegetables, air 0 per year. 25 mSievert soil per year 0. 15 millisieverts;**** perspective once 0. 02 millisieverts. And these substances that you bring with you will cause 24 microsieverts in a day, which is about 8,700 microsieverts in a year, which is 8 in a year. 7 millisieverts, which is a serious excess. ”

"My dog sniffed the ash layer and soon vomited, is it because of this nuclear radiation?" Su Jing asked, while paying a slight attention to the young man, thinking that no wonder Jiang Ji asked him to answer, this answer is really comprehensive enough.

"It's certainly not, this level of radiation doesn't cause vomiting, which may be due to sulfur dioxide or other toxic substances. Of course, just smelling it, it shouldn't be a big problem, as long as you go to a place with good air, it will recover soon. Jiang Ji explained, and then asked, "Boss, I don't know where you brought this vacuum cleaner and ash layer from?"

"This is from a friend's research room. Su Jing was vague.

"In this way, if there is any useful research material, you can take me there, after all, the radiation dose rate is not very high, as long as the protection is appropriate, there is no problem. Jiang Ji said that this radiation dose rate is seriously high for life, but it is indeed acceptable for researchers.

"It's not necessary, but how to protect it, you tell me and help me develop a perfect plan. For the sake of safety, it is necessary to be able to block even a hundred times the radiation dose rate of these gray layers. Su Jing said, just spraying out a little gray layer, the radiation dose rate is so high, the radiation dose rate of the garbage inside the garbage station, I'm afraid it really has to be a hundred times, it's better to be fully prepared.

"The best protective clothing is a special protective clothing lined with lead, the thicker the better, of course, the thicker the heavier, the more you can wear a hundred pounds, boss?" Jiang Ji thought for a while, and then said.

"Let's make about 300 pounds. Su Jing thought for a while.

"Three hundred catties?" Jiang Ji and the two young men were stunned for a while, one hundred catties is already very exaggerated, that is the place where the nuclear leak will be worn, it is basically difficult to move when you put it on, two hundred catties can you walk around when you put it on?

"Try it first, and then you'll move with a rope. Su Jing said, of course, he didn't really plan to do so, but the weight of 300 catties is nothing to himself, even if he wears 300 catties of clothes, he can move freely. If he wasn't afraid that it would be shocking if it continued to increase, and at the same time it would be too large, he would have added it to five hundred catties. After all, nuclear radiation is not a joke, it can cause cancer and genetic mutations at every turn.

"Okay. Jiang Jida didn't think that the three-hundred-pound clothes were practical, but the boss was Su Jing, so he had to listen. Anyway, he is responsible for making it, whether he can wear it or not, that is Su Jing's business.

Jiang Ji sent someone to get all the materials needed, and then began to build protective clothing, Su Jing was not idle, called the young man named Xiaobin aside, and asked him what to do with the nuclear radiation material. (To be continued.) )
