Characteristics of radioactive pollution: The toxicity of most radionuclides, calculated based on the weight of the poison itself, is higher than that of ordinary chemical poisons. Based on the effects of radioactive damage, it may affect heredity and bring hidden dangers to future generations. .
The magnitude of the radioactive dose can only be detected by radiation detectors and cannot be known by human sensory organs. The secondary irradiation of rays is penetrating, especially r-rays, which can penetrate a certain thickness of barrier layer. Radionuclides have the ability to decay, and radioactive activity can only be weakened through natural decay.
Among the elements in nature and artificial production, some can decay automatically and emit rays invisible to the naked eye. These elements are collectively called radioactive elements or radioactive substances.
Under natural conditions, rays from the universe and radioactive elements in the earth's environment generally do not cause harm to living things. Since the 1950s, human activities have greatly increased artificial radiation and artificial radioactive substances.
The intensity of rays in the environment increases, endangering the survival of living things, resulting in radioactive pollution. Radioactive contamination is difficult to eliminate, and the intensity of the rays can only weaken over time.
