Radiation can have various health effects depending on the type and amount of exposure. Low levels of radiation, such as that from natural sources like cosmic rays or radon, typically pose minimal risk. However, high levels of exposure, such as from X-rays or nuclear accidents, can lead to acute health issues, including skin burns and radiation sickness. Long-term exposure to radiation may increase the risk of developing cancer and other serious health conditions. The risk is influenced by factors such as age, sex, and overall health. Understanding these effects is crucial for safety in medical settings and environments with potential radiation exposure.
