Explanation:

Lead Apron are popular names for the Plumbiferous Apron, a type of mandatory uniform known as the VPR (Radiation Protection Clothing) that aims to protect the wearer from possible exposure to radiation from radiological devices. Safety is activated as soon as the lead components that make up the lead structure block the passage of X-ray photons, preventing ionizing radiation from reaching those wearing the lead apron.

In short, the lead apron is mainly used for radiographic examinations in order to reduce the radiation exposure dose that affects both the patient and the operator as much as possible.
