What thickness should a lead apron be to provide adequate protection?

Explanation:
The protective value of a lead apron comes from its shielding, measured as lead-equivalent thickness. For most diagnostic x-ray energies, a minimum of 0.25 mm of lead-equivalent shielding is sufficient to reduce scatter and leakage to a safe level for the torso while keeping the apron practical to wear. A thinner option like 0.15 mm would provide less attenuation and could leave you more exposed, while thicker options such as 0.3 mm or 0.5 mm offer greater attenuation but are heavier and usually unnecessary for standard practices. Therefore, 0.25 mm is the commonly recommended minimum thickness for adequate protection.
