What are the main routes of exposure to radiation in adults?

Adults can be exposed to radiation primarily through inhalation and ingestion pathways. Inhalation occurs when radioactive particles enter the respiratory system and may deposit in lung tissues, leading to potential health risks. This route is particularly relevant in occupational settings where radioactive materials may be present in the air.

Ingestion involves the consumption of food or water that has been contaminated with radioactive substances. This can occur through environmental contamination or improper handling of radioactive materials. Both inhalation and ingestion contribute significantly to the overall radiation dose received by adults in various settings, especially those working in industries related to nuclear power, medical applications, or environmental exposure.

While injection and skin absorption can be routes of exposure for specific contaminants, they are generally less common for radiation exposure when compared to inhalation and ingestion. Therefore, the recognition of inhalation and ingestion as the main routes underscores the importance of monitoring and controlling these exposure pathways in environments where radiation is a concern.
