On August 1, 1999, a poorly preserved metal bucket was recovered from a river in Lancaster, Pennsylvania.Inside the metal bucket was a smaller, white plastic bucket containing a human skull partially embedded in a gray plastic material.
The most common of these medical procedures involve the use of x-rays — a type of radiation that can pass through our skin.
When x-rayed, our bones and other structures cast shadows because they are denser than our skin, and those shadows can be detected on photographic film.
In addition, radiation has useful applications in such areas as agriculture, archaeology (carbon dating), space exploration, law enforcement, geology (including mining), and many others.

The recovered objects were taken to the local medical examiner to have the skull removed from the plastic matrix and to be analyzed.
