Cesium: I'm cesium, golden yellow, and I have a lot of power when I encounter water.

Uranium: Awesome, chemical element brothers!

Cesium: Uranium gods, old-timers in the radiation world.

Uranium: I am uranium, and my radioisotope brothers are superb, and they are the materials used by humans to make atomic bombs.

Cobalt: My radioisotope brother emits gamma rays, breeding, sterilization.

Cesium: I also have a radioisotope brother, Cs137, which also emits gamma rays.

Hydrogen: Who doesn't have a few isotope brothers in our chemical elements? I have three isotopes in nature, among which tritium is also radioactive.

Uranium replies to hydrogen: Big Brother haunts.

Cobalt restores hydrogen: Great, our big brother, as the most hydrogen chemical element, there are also radioisotope brothers, and the half-life is more than ten years.

Hydrogen: Well, this is Xiao Cesium's circle of friends, let's post it in my autobiography.

Cesium: Okay, Big Brother wants to see it, so he immediately posted it.

I'm cesium.

Atomic number: 55.

Pure Me is a golden metal.

I am very soft, have a low melting point, and are very susceptible to oxidation in the air, so the pure nature of me is unstable.

I can react violently with water to produce hydrogen, a process that often leads to explosions.

Pure me, I can form a gray-blue oxide in the air, which has a very low ignition point and can be natural.

My flame is a beautiful deep fuchsia.

There is no single form of me in nature, I am only distributed on earth in the form of salt.

I have a lot of isotope brothers.

The most famous of these is the radioisotope brother Cs137.

CS137 can emit gamma rays as a radiation source, which is used in breeding, sterilization, cancer treatment, and industrial flaw detection.

Once an organism ingests my Cs137 soluble compound, Cs137 can enter the cell and cause internal damage.

If an organism is exposed to gamma radiation emitted by Cs137, it will develop symptoms of radiation sickness.

Gamma rays act directly on the nucleus of microorganisms, causing the chromosomes in the nucleus to be interrupted and killed.

Gamma rays are transmitted through energy, damaging organelles and inactivating enzymes, resulting in the death of microorganisms.

When gamma rays hit a living person, the human being will disintegrate from the inside out, just like a microorganism killed by the radiation.

The severity of radiation injury varies depending on the dose of radiation.

When organisms are irradiated with 100-1000 cGy, bone marrow hematopoiesis is impaired, pancytopenia, infection, hemorrhage, and metabolic disorders.

The higher the dose received, the more severe the symptoms.

When the organism is irradiated with 1000-5000cGy, the intestine is damaged, vomiting, bloody stool, diarrhea can reach dozens of times a day, the diarrhea contains a large amount of intestinal mucosal shedding, and the intestine seems to be melted.

There are no treated surviving cases of enteric radiation sickness.

Uranium: Radioisotope brothers, natural enemies of living organisms.

Cobalt: The invisible killer, it's our radioisotope brothers.

Thallium: Although we are poisonous and radioactive, and sometimes invisible killers, we are also very versatile, or humans like to concentrate and purify us.

Cobalt: The radioactive isotope of small cesium, it's amazing.

Cesium reverts cobalt: Cobalt-60 is also very powerful, with a shorter half-life than my Cs137, and is more popular with humans as a radioactive source.

Cobalt restores cesium: Cesium atomic clock, also loved by humans.
