Which of the following is NOT a route that pesticides can enter the body?

Pesticides can enter the body through several pathways, including inhalation, ingestion, and dermal contact. Each of these routes allows substances to be absorbed into the body and can pose health risks to individuals handling or exposed to pesticides.

Inhalation occurs when pesticides are breathed in as vapors or aerosols, allowing them to enter the respiratory system. Ingestion involves swallowing pesticides, which can happen through contaminated food, drinks, or hands. Dermal contact refers to pesticides being absorbed through the skin, highlighting the importance of protective clothing while handling pesticides.

Radiation is not a route of exposure for pesticides. While radiation can have various health impacts, it is not a mechanism through which pesticides enter the body. This clarifies why radiation is the correct choice as the option that does not represent a route of pesticide entry. Understanding these modes of exposure is crucial for ensuring safety and implementing proper handling practices in pesticide application.
