What does "external exposure" to radiation mean?

• A. Exposure from radioactive contamination
• B. Exposure from sources outside the body
• C. Exposure from inhalation of radioactive particles
• D. Exposure due to internal radiation sources

Answer: (B)

"External exposure" to radiation refers specifically to exposure from sources that are located outside the body. This type of exposure can occur from various external radiation sources, such as radioactive materials, X-ray machines, or cosmic radiation. External exposure does not involve any radioactive material that has entered the body, which differentiates it from internal exposure. Understanding this concept is crucial for radiation safety, as it helps to identify the various pathways through which individuals can be affected by radiation. This knowledge allows for the implementation of appropriate safety measures to minimize exposure, particularly in environments where radiation is present.
