Radioactive Contamination - GCSE Physics Definition

Radioactive contamination occurs when harmful radioactive materials spread onto or into objects, including people and animals. These materials will be radioactive until the source of the radiation is removed. Radioactive contamination can happen through accidents at nuclear power plants, improper disposal of nuclear waste, or when radioactive substances are not handled safely. It is important to avoid contact with contaminated objects and areas because the radiation can damage cells in our bodies and cause health problems. However, radioactive contamination can be used for medical purposes. For example, diagnosing certain cancers requires patients to drink radioactive mixtures so that tumours and damaged tissue can show up on a scanner. Doctors and scientists use protective gear and special tools to measure and control contamination to keep people and the environment safe.
