Final answer:
The minimum thickness recommended for protective gloves or gauntlets used in radiology to adequately shield from harmful radiation is 0.25 mm Pb (lead equivalence).
Step-by-step explanation:
Protective gloves or gauntlets used in radiology are designed to shield the hands from harmful radiation during medical procedures involving X-rays or other forms of ionizing radiation. The thickness of the protective lead in gloves is crucial for ensuring adequate protection. Although specific requirements can vary by guidelines and use-case, having knowledge about what thickness is generally recommended is essential for those working in such environments. Typically, the minimum thickness for radiology gloves is 0.25 mm Pb, which stands for lead (Pb) equivalence. This thickness provides a balance between radiation protection and manual dexterity, allowing medical personnel to perform their tasks while minimizing radiation exposure to their hands.
