Is an atomic energy

Energy of the atomic nuclei
"Nuclear energy" describes the energy contained in atomic nuclei. In colloquial language one also says "atomic energy". 150 years ago scientists were convinced that atoms are the smallest, indivisible building blocks of our matter. In 1938 the German physicists Otto Hahn and Fritz Strassmann succeeded in splitting atoms into smaller parts. A lot of energy is generated during this complicated process. Radioactive radiation is generated at the same time. It is extremely dangerous for people.
Use for nuclear weapons
Many countries in the world have the knowledge of how nuclear energy can be obtained. Some states have used this technology to manufacture weapons (atomic bombs, nuclear missiles, nuclear grenades). But the weapons were only used once at the end of World War II. The effects were terrible. The atomic bombs that the Americans dropped on Hiroshima and Nagasaki in 1945 wreaked havoc. Thousands of people died. Many people lost their health as a result of the radioactive radiation, and many died as a result of the radiation.
Peaceful use: energy generation
Atomic energy is used not only for the manufacture of weapons, but also for peaceful purposes. One uses the heat radiation that arises during the splitting. It converts water into steam, which in turn drives turbines to generate electricity. In nuclear power plants, nuclear fission is carried out in a controlled manner during this process. The fuel is usually the atomic nuclei of uranium or plutonium. Thick protective shells made of concrete and steel are built in these power plants to protect against the dangerous radioactive radiation that arises during the fission and conversion process. Nuclear fission is controlled by a highly complex technique.
Radioactive radiation hazards
The complicated process of atomic splitting creates a great deal of energy. But there is also radioactive radiation. It is extremely dangerous for humans because the radiation attacks human organs and can cause cancer. To this day, this technology cannot be safely mastered. Serious accidents have occurred time and again in the past: in Harrisburg / USA (1979) and in Chernobyl / Ukraine (1986) and in the Japanese nuclear power plant Fukushima (2011). After an earthquake and a huge tsunami in Japan, the damage to the nuclear power plants showed the risks this type of energy generation poses for people. The danger of radioactive radiation entering the environment is the great risk that this technology poses. If the radiation is very high, it can even lead to death.
Unsolved problem: final disposal

Another very high risk for people and the environment is that the waste from the nuclear power plants can emit dangerous radiation for several thousand years. A safe final repository for the waste that arises from these incineration processes has so far been found in Germany and in no other country in the world.

Germany: Farewell to atomic energy
After the terrible accident at the Fukushima nuclear power plant, the federal government decided that electricity should no longer be generated in Germany using nuclear power plants. Therefore, all nuclear power plants will be switched off by 2022 at the latest. There are currently six nuclear power plants still on the grid. According to the Atomic Energy Act, the three youngest reactors will be shut down in 2022 at the latest, the others in 2021 at the latest.
Use in medicine

In medicine, radioactive rays are used specifically to detect diseases in the body with the help of X-rays, for example. Radiation is also used in cancer therapy to specifically destroy rapidly growing tissue such as tumors.
