What benefits and harm derived from exposure to radiation?

Exposure to radiation has both beneficial and harmful effects. On the positive side, controlled radiation is used in medical treatments, such as cancer radiotherapy and diagnostic imaging like X-rays and CT scans, helping to diagnose and treat various health conditions. Conversely, excessive or uncontrolled exposure to radiation can lead to serious health risks, including radiation sickness, increased cancer risk, and genetic mutations. Balancing these effects is crucial in fields like medicine and nuclear energy.
