Which of the following is not considered a type of personal radiation shielding?

Personal radiation shielding is designed to protect individuals from exposure to ionizing radiation during medical procedures, particularly in radiography. The types of personal radiation shielding include devices that physically block or reduce the intensity of radiation reaching the person.

Lead aprons are common protective garments that contain lead and are worn by patients and healthcare professionals to shield vital organs from radiation scatter during X-ray procedures. Protective goggles are designed to shield the eyes from radiation exposure, providing an additional layer of safety for workers in environments with potential radiation hazards. A shielding helmet, which may incorporate lead or other materials, protects the head from radiation during specific procedures.

Shadow shielding, however, is distinct from personal shielding methods. It involves using a barrier or a physical structure to cast a "shadow" that interrupts the path of radiation, typically relying on the placement of equipment rather than a wearable shield. Since shadow shielding does not represent a personal item worn or wielded by the individual, it is not classified as a type of personal radiation shielding.

This distinction helps clarify the role and application of each type of shielding in the context of protecting individuals from radiation exposure.
