"It turned out to be radon." Jiayi was surprised to see the separated gas. "I finally found a radioactive element. There must be other radioactive elements in it, so I will separate it for a while."

Jiayi is still familiar with radon gas. Uranium may be the most well-known radioactive element, but radon gas is the most easily exposed to radioactive substance. Although people may not realize it, radon has a short half-life, but it is very common in nature, especially in stone. If marble is used for home decoration, it has requirements for the content of radon.

However, the half-life of radon is particularly short, and the longest one is only a little over 3 days. In the chemical test paper, the longest radioactive element question is calculated by people taking radon as an example. The main source of radon is radium, which is the radium discovered by Madame Curie. Radon is produced after radium decays, and radon is decayed by thorium, and thorium is decayed by uranium.

Following this idea, Jiayi found the elements of uranium, radium, and thorium. After re-analyzing the gas, helium was found. After this long series of analysis, almost all the radioactive elements in this curse stone were analyzed.

Among this stone, the radium content is the highest, followed by radon, then helium, followed by uranium and thorium. The uranium content that Jiayi is most concerned about is not high.

Jia looked at the several elements separated in front of him, which almost formed a complete chain. According to the decay, the alpha particles generated during the decay capture electrons and form helium. The alpha rays are rays formed by the nucleus of helium. After a few more decays, the final result is lead.

"It seems that the organization that provides this curse stone should have mastered the refining of radioactive elements, and there should be a radioactive element ore, which is likely to be a uranium ore." Jia Yi murmured in a low voice, and his saliva was about to flow down.

If someone hadn't deliberately extracted it, the content of radium and radon in this stone would not be so high. The half-life of radium and radon is relatively short, so in natural minerals, the content of these two substances is very weak, far lower than the content of uranium. It is just because radium and radon have the strongest radioactivity and kill the human body the most. After being targeted purified, there will be so many of these two components in this curse stone.

However, their extraction methods should not be very powerful. Although the content of radium is high, compared with natural minerals, all radioactive substances are added up to less than 10%.

Jiayi despised them a little, and the extraction methods were a little rough.

"I don't know where their mine is?"

All the discoveries were sorted into papers, and with helium, his ultra-low temperature experiment could go a step further. Unfortunately, there is not much helium now. Even if he purified all the helium contained in the Curse Stone, the amount was too small, which was completely insufficient to conduct the experiment.

He could only arrange an adsorption array on the roof, and then continuously blow the wind through a wind-type array, using this method to continuously collect helium. However, the helium content in the air is too small, and I don’t know how long it will take to collect helium that can be used for experiments.

On the other side, Trivis seemed a little depressed and said dullly: "We are now in trouble in research on low temperatures. Although we have obtained liquid hydrogen, there is no way to explore lower temperatures. Not to mention obtaining absolute zero degrees, it is impossible to get close to them now."

Jia had foreseeed this in the morning, but Travis and the others didn't know about it. They always thought that they could truly obtain absolute zero through various means.

"This is not your fault. It is not that easy to get absolute zero. Even the forbidden spell of the ice and snow system has reached absolute zero. You have accumulated a lot of experimental data now. You can summarize the experimental results like Loriel and others to see if you have any discoveries."

He said, paused for a moment, thought for a moment, and then said: "I discovered a new substance in my study of cursed stones. Through this substance, we may be able to get closer to absolute zero. Since we have been studying absolute zero, the temperature coordinate system with ice water as the reference system is not suitable. We use absolute zero as the new zero and start a new reference system, which is called opening."
