Which organ is known to receive the highest dose of radiation exposure?

The skin is known to receive the highest dose of radiation exposure during fluoroscopic procedures. This is primarily due to its proximity to the radiation source and the way fluoroscopy is conducted. When imaging is performed, the skin often experiences direct exposure to the x-ray beams, resulting in higher doses compared to internal organs that are shielded by bone and other tissues.

Fluoroscopy procedures tend to concentrate radiation on the surface where the x-ray beam exits, making the skin susceptible to significant radiation exposure, especially in areas where the beam is directed for extended periods. This increased exposure can lead to conditions such as radiation dermatitis or other skin injuries, which is why it's crucial for radiology professionals to monitor skin doses and utilize shielding whenever possible.

In contrast, while the brain, heart, and liver may receive some level of radiation during fluoroscopic procedures, their doses are generally lower due to the filtering effect of overlying tissues and the nature of the x-ray beam as it penetrates deeper into the body.
