Periodically during inspections of radioactive material use areas, we find "bare" lead bricks and other pieces of lead shielding. These items must be coated or painted in some manner to prevent the spread of lead dust due to oxidation and potential transfer of lead to individuals handling these materials with bare hands. If you are using lead for shielding and it is not "encapsulated", contact radiation safety for assistance with encapsulation.
Do not dispose of lead in the regular trash or in radioactive or hazardous waste containers.
All disposal of lead bricks should be through EHS-Radiation Safety.
Lead Used for Radiation Shielding
Shown here is a "bare" gray oxidized lead brick, a piece of lead painted with a red "sealant" type paint and a lead brick coated with heavy duty black "duct tape" to "encapsulate"
