The minimum lead equivalent required for lead gloves is 0.25 mm. This thickness provides adequate protection against radiation exposure typically encountered in radiologic procedures. Lead gloves are essential for protecting the hands during fluoroscopy and other imaging techniques where radiation is used, since the hands are often positioned close to the radiation source. While thicker lead equivalents, such as 0.50 mm or above, offer increased protection, the 0.25 mm level is generally sufficient for most clinical settings where gloves are needed, making it a practical choice. Understanding the balance between protection and comfort is key in clinical applications, which is why lead gloves are designed to provide the basic level of shielding necessary for safe practices during diagnostic imaging.
