Radiation is part of everyday life. We are all exposed to radiation from natural sources e.g. radon gas and manmade activity e.g. for medical reasons.
For more information on types of radiation, the effects of radiation on people and radiation exposure please see the Public Health England document 'Basic Concepts of Radiation'.
Businesses and organisations who work with or transport radioactive material are heavily regulated to ensure they do so safely without risk of harm to the public or environment.
