What are the two types of radiation exposure?

The two types of radiation exposure are internal and external. Internal exposure occurs when radioactive materials are inhaled, ingested, or enter the body through wounds, leading to radiation emitting from inside the body. This can result from consuming contaminated food or water, or from occupational exposure in certain environments.

External exposure, on the other hand, occurs when a person is exposed to radiation from a source outside the body. This can be from gamma rays, X-rays, or other forms of radiation that can penetrate the body and cause biological effects. Sources of external radiation can include medical imaging equipment, or being near radioactive materials.

Understanding the distinction between internal and external radiation exposure is crucial for assessing risks, implementing safety measures, and creating effective treatment protocols for individuals potentially exposed to radiation.
