Lead is commonly used in heavy metal-based paints as a pigment and in radiation shields due to its high density and effectiveness in absorbing radiation.

The ozone layer shields us from ultraviolet radiation.
The shields at the dentist are typically made from lead, which is a dense material that helps block harmful radiation during dental x-rays. Lead is effective in absorbing the radiation, protecting both the patient and the dental staff from unnecessary exposure.
Heavy metals as lead retain nuclear radiations.

Plastic itself does not reduce radiation. However, certain types of plastic materials can act as a barrier to some forms of radiation. For example, thick plastic shields can help block alpha and beta radiation but are not effective against gamma radiation. Specialized materials like lead and concrete are more commonly used for radiation shielding.
Lead is used to make various products such as batteries, radiation shields, and bullets. Additionally, lead is used in the manufacturing of certain types of glass and as a stabilizer in PVC plastics.
