Radiation is a form of energy that is emitted from various sources, such as the sun, nuclear power plants, and medical devices. It can harm us by damaging our cells and DNA, leading to health problems like cancer.
The most common types of radiation that can harm us are ionizing radiation, such as gamma rays and X-rays, and non-ionizing radiation, such as UV rays and radio waves. Both types have the potential to cause harm depending on the dose and duration of exposure.
The most common source of radiation exposure for humans is from natural sources, such as radon gas, which is present in soil and rocks. Other sources include medical procedures, like X-rays and CT scans, and nuclear power plants.
There are several ways to protect ourselves from harmful radiation, such as limiting our exposure to sources, using protective measures like lead aprons during medical procedures, and following safety guidelines and regulations set by authorities.
No, radiation exposure cannot be completely avoided as it is a natural and unavoidable part of our environment. However, we can minimize our exposure by being aware of potential sources and taking necessary precautions to protect ourselves.
