IMPROVEMENTS RELATING TO CONTAINERS FOR RADIOACTIVE SOURCES
Patent
·
OSTI ID:4117548
A container for radiation sources in which a path for collimated radiation may be opened or closed with safety is described. A body of lead or other dense material has a passage to locate the source and a cylindrical valve member interposed in the passage, the valve having a passage coinciding with that in the bcdy and arranged to be rotatable through 90 deg so that a path may be opened or closed for radiation by valve rotation. The body also may be formed with a plurality of passages and valve members when a plurality of collimated beams is desired. Metal sheaths may be provided on the outside of the body to protect it from abrasion and fire and in the interface between the body and the valve member to reduce abrasion due to rotation. (D.L.C.)
