A brainstorming session immediately began.

Based on his meager knowledge of physics, he knew that radiation was divided into two types:

Ionizing radiation, non-ionizing radiation.

Non-ionizing radiation includes light, microwaves, and electromagnetic waves used in communications, but it does not have the desire to devour.

That can be ruled out.

Ionizing radiation includes many different types.

Gamma radiation and X-rays belong to the category of "high-energy electromagnetic waves" in ionizing radiation.

Occasionally, some gamma radiation escapes from the universe and spills onto the Earth's surface.

But Liu Kai stood in the open space for a long time without sensing any desire to devour.

This category is also excluded!

Therefore, ionizing radiation is reduced to only one last category: "particles".

Alpha radiation, beta radiation, neutron radiation.

After thinking for a long time, Liu Kai finally came to the most likely conclusion.

At the same time, they were also planning where to go next to consume more radioactive materials.

Dreams are beautiful, but reality is harsh.

"Particle" ionizing radiation is not something you can just pick up anywhere.

Whether in times of peace or during this cold snap and apocalypse, it is far beyond the reach of ordinary people.

Even for government insiders who want to access these strictly controlled items, the procedures are extremely complicated.

Continuing to mine seems like a good option.

After all, there are quite a few uranium mines within China's borders.

But the idea only flashed through his mind and was quickly rejected by Liu Kai.

Not to mention that there are no uranium mines around Fenghai City.

Even if it were available, I wouldn't dare to do it.

During this period, petty theft involving iridium and platinum occurred.

Even if they are caught, it's just greed at most.

However, illegally mining uranium is a serious offense.

That was blatant rebellion!

Just when Liu Kai was at his wit's end, a sudden inspiration struck him.

Why bother producing radioactive elements domestically?

Stealing from abroad is also an option.
