Understanding Radiation Exposure: Types and Risks
Learn about different types of radiation exposure including contamination and irradiation. Radioactive contamination can be external or internal, while internal exposure occurs from ingesting or inhaling radioactive substances. External exposure, though less dangerous, can still pose risks. Explore the dangers and implications of various types of exposure to ionizing radiation.

Types of exposure Radiation exposure may involve - Contamination - Irradiation
Radioactive contamination Radioactive contamination is the unintended contact with and retention of radioactive material, usually as a dust or liquid. Contamination may be External Internal
Internal exposure occurs when the source of ionising radiations is located inside the organism, usually as a consequence of ingestion or inhalation of radioactive substances. This sort of exposure is frequently used radioactive tracers are placed inside the body for a diagnostic or therapeutic purpose. in medicine, when
External exposure on the other hand, takes place when the radioactive source is located outside the body. Internal exposure is the most dangerous as the radioactive atoms are fixed to your body.
