8 Radioactivity and DeathAfter discussing the potential terrorist threats, I finally started to understand the knowledge about nuclear weapons. According to the textbook, an energy emitted by radioactive materials in the form of waves or particles is called nuclear radiation. Nuclear explosions and nuclear accidents all produce nuclear radiation. Therefore, not only terrorists will bring us a nuclear threat. The improper operation of nuclear power plants will also cause great harm to the surrounding residents.

In the long-term practice and application, people find that a small amount of radiation does not endanger human health. Excessive radioactive radiation causes harm to the human body, causing illness, cancer, and death. The longer the exposure time, the greater the radiation dose received and the greater the hazard. Here, I deliberately went to understand the definition of cancer. Cancer is not a type of deadly virus which is very different from my previous impression. Usually when somatic cells are damaged or aged to a certain degree, they will eliminate themselves. When this self-eliminating ability disappears, the cells acquire “eternal life” and can uncontrollably continue to divide, which evolves into cancer.

The land and water resources were seriously polluted, and thousands of people were forced to leave their homes. Chernobyl became a deserted barren land. Ten years later, radioactivity continues to threaten the lives and health of some 8 million people in Belarus, Ukraine and Russia.

Experts said that the consequences of the Chernobyl accident will continue for a hundred years.
