Chapter 1511 (1/2)

In the world where Chen Hui came, when the word radiation is mentioned, most people think that radiation is harmful. This is because for people in the world where Chen Hui came, what they can think of is basically nuclear radiation.

In fact, radiation refers to the phenomenon that a part of the electromagnetic energy emitted by the field source departs from the field source and propagates to the distance, and then does not return to the field source. The energy diffuses outward in the form of electromagnetic waves or particles, such as alpha particles and beta particles.

All objects in nature, as long as the temperature is above the absolute temperature zero, always transmit heat to the outside in the form of electromagnetic waves and particles. This way of transmitting energy is called radiation.

The radiation energy radiates from the radiation source in all directions.

The energy emitted by radiation is called radiant energy.

Radiation is calculated in terms of roentgen per hour. One important feature of radiation is that it is equivalent. No matter the object or gas, the temperature is high or low, it radiates outward. Object a can radiate to object B, and object B can radiate to a.

The term is generally used in ionizing radiation.

Radiation itself is a neutral word, but the radiation of some substances may bring harm.

Thus, it can be seen that nuclear radiation is a kind of harmful radiation, but nuclear radiation is only one of them, and not all radiation is harmful to human body.

The Tiankeng near the Tu Nationality Settlement is just their opinion. Strictly speaking, it should be a meteorite crater.

Because Tiankeng is actually a geomorphic feature, which refers to the karst negative terrain with steep peripheral wall, depth and diameter up to several hundred meters developed in carbonate karst area. It has huge volume, and its bottom is connected with the underground river, or there is evidence that the underground river has moved.

The area inhabited by the Tu people is totally out of line with the landform of Tiankeng.

In fact, not only the areas inhabited by the Tu nationality, but also the areas inhabited by the five human nationalities, are completely inconsistent with the landform features such as Tiankeng.

This is why Chen Hui and Zhou qiuchu will decide that the crater they are talking about should be a meteorite crater.

A crater is a circular crater formed on the surface of a planet, satellite, asteroid or other celestial body by meteorite impact. A larger crater is also known as a crater. The center of a crater with a diameter of more than four kilometers may form a central cone.

The crater may be filled with water due to rainfall and other reasons, forming an impact lake.

Chen Hui and Zhou qiuchu did not notice anything wrong except the lush trees along the way. Occasionally, they were startled by Chen Hui and Zhou qiuchu and ran out, and the escaped animals did not find anything wrong. Chen Hui and Zhou qiuchu also concluded that the crater might not have radiation, or it might have radiation, Under the standard of harmlessness to human body.

If the crater has harmful radiation, it may cause the animals nearby to mutate.

After all, the leader of the Tu ethnic group only told Chen Hui that there was a crater nearby, indicating that the crater had existed for a long time, at least before they came here to live.

If after they came to live nearby, the meteorite landed and formed a crater, and there was a huge impact, it would be known to them. They would not call it a crater, but would tell Chen Hui about flying rocks outside the sky.

After Chen Hui and Zhou qiuchu arrived near the crater, they couldn't help looking at each other, because this crater is completely different from what they know about it.
