J. Edgar Hoover's coffin was lined with lead to prevent grave robbers from stealing his body due to his high-profile status as the long-time director of the FBI. The lead lining was intended to deter any potential attempts to steal or tamper with his remains.

Lead helps delay the decay of the body.
A coffin made from lead.
I understand the casket was lead-lined, with a glass viewing window. This was discussed during the televised coverage of the funeral. Addition: Diana's coffin was made of oak with an inner metal liner made of lead. The liner had a glass viewing window.
For her funeral she was in a lead coffin (covered in purple velvet and a life-like effigy). But she must have had a double coffin (a coffin inside a coffin) because in the 1800's when her tomb was opened it was reported she had a wooden coffin so her wooden coffin must have been inside the lead one, although I cannot confirm this, its only an assumption. its also possible that she had a lead coffin for the funeral and her body was then moved to a wood one later. point being, she had one lead one, and one wood one.
As far as I know, lead is used as a sort of insulator in the coffin. It prevents unpleasant odors for the decomposing bodies to reach other people.

To protect his body in the event of nuclear war. A more simply reason might be that, perhaps, he was buried in a Belmont casket. The (former) Belmont Casket Company of Columbus, Ohio was famous for its lead coated steel caskets. The lead coating had an anti-corrosion effect, giving the carbon steel properties similar to that of stainless steel. President Lyndon B. Johnson, e.g., was buried in a Belmont lead coated steel casket. Pictures of Hoover's funeral seem to indicate that he might have been buried in one of the double lid Belmont "Masterpiece" caskets, the top of the line model of the company. A solid bronze type of the "Masterpiece" casket (with more ornamental caskets handles than those of J. Edgar's casket) was used for the burial of Marilyn Monroe.
Princess Diana is said to have had one of the coffins typically used for British Royals: an oak coffin in the shape of a hexagon; inside a coffin liner made of lead.
The first coffin is tin, the second mahogany, the third and fourth lead, the fifth ebony, and the sixth oak. After his body was embalmed the number off coffins fulfilled a number of purposes: Led-lined coffins can prevent complete decomposition of the body, other layers are for security of the body and the final elaborate coffin acts as symbolism that this person was of great importance.
Natural ones are called orifices. Artificial ones are called stomas.
Yes, the heavy aprons used in the X-RAY room are lined with lead.
