disadvatages of radioactivity in 250 words
Answers
Answer:
If radiation collides with molecules in the air or in your body, it throws out of them electrons. By throwing out electrons you produce charged particles called ions. This means it is the radiation responsible for ionising molecules.
If this happens in our body, the cells may die or they may undergo a change called a mutation. The result is called radiation sickness. A large dose of radiation will cause death!
Small doses of radiation over a long period of time can cause the cells to multiply. However, these cells are mutated. Some time later cancer may occur.
Answer:
Exposure to large amounts of radioactivity can cause nausea, vomiting, hair loss, diarrhea, hemorrhage, destruction of the intestinal lining, central nervous system damage, and death. It also causes DNA damage and raises the risk of cancer, particularly in young children and fetuses.
