What is the impact of nuclear sewage?

Effects of nuclear sewage: water pollution, soil pollution, biological enrichment and radiation hazards.

1. Water pollution: When nuclear sewage is discharged into the sea, rivers and other water bodies, the water body will be polluted by radioactive substances. After entering the water, radioactive substances will enter organisms through the food chain, thus affecting the stability and biodiversity of marine ecosystems.

2. Soil pollution: Nuclear sewage may enter the soil through rainfall and groundwater, causing radioactive pollution of the soil. Crops and plants exposed to radioactive contaminated soil for a long time will be affected by radiation.

3. Bioaccumulation: Bioaccumulation of radioactive substances in the environment may lead to an increase in the concentration of some radioactive elements in organisms.

4. Radiation hazard: Radioactive substances in nuclear sewage may enter the atmospheric environment through water evaporation, causing radiation hazard to surrounding residents and ecological environment.

Elements contained in nuclear sewage

1, uranium (u): Uranium is the most commonly used fuel in nuclear reactors, and its fission products contain a large number of radioactive isotopes, such as uranium -235 and uranium -238.

2. Plutonium (Pu): Plutonium is a radioactive metal that can be used to make atomic bombs. Plutonium -239 is a splittable plutonium isotope, and its decay products contain high-energy neutrons.

3. Actinides: Actinides include praseodymium (Ac), Plutonium (Pu) and Neptunium (Sm). The radioactive decay of these elements will produce particles and radiation.

4. Transuranium elements: Transuranium elements refer to elements with atomic numbers greater than uranium, such as americium (Am), curium (Cm) and thulium (Bk). Particles and radiation produced by radioactive decay of these elements are also harmful to the environment and living things.
