Abstract
A shielded packaging system is formed by a top panel and a bottom panel that are connected to one another along a preselected extent of their respective peripheral edges. An opening is formed along the unconnected extent and provides access to the space between the panels that holds radioactive items. Each panel includes at least two layers of lead foil so that if a pinhole is formed in either layer, the probability of two pinholes lining up and enabling radiation to escape from the space is minimal. The layers of lead foil have at least one ridge formed in them at their respective peripheral edges so that radiation traveling in a straight path parallel to the top and bottom panels encounters the ridges and cannot escape through the edges of the package.
