How does radiation affect the human body?

Radiation can damage cells and DNA, leading to cancer and other health problems.

Radiation is energy that travels through space and can penetrate materials. When radiation interacts with the human body, it can damage cells and DNA. This damage can lead to cancer and other health problems.

The amount of radiation a person is exposed to determines the severity of the effects. High doses of radiation can cause radiation sickness, which can lead to nausea, vomiting, and even death. Lower doses of radiation can increase the risk of cancer over time.

Different types of radiation have different effects on the body. For example, alpha particles can be stopped by a sheet of paper and are not harmful unless they are ingested or inhaled. Beta particles can penetrate the skin and cause burns, while gamma rays can pass through the body and cause damage to internal organs.

Radiation exposure can come from natural sources, such as the sun and radon gas, or from man-made sources, such as X-rays and nuclear power plants. It is important to limit exposure to radiation and take precautions when working with radioactive materials.

Overall, radiation can have serious effects on the human body, and it is important to understand the risks and take steps to protect ourselves from exposure.
