A phosphor screen with a smooth-surfaced phosphor layer is formed by casting a phosphor layer in liquid form on a sheet to which the layer adheres without bonding. The exposed surface of the layer is then solidified and bonded to a permanent substrate. The sheet on which the phosphor has been cast is then removed, leaving a smooth exposed surface, which may then be covered with a transparent protective layer.

Smooth-surfaced phosphor screen

A stimulable phosphor having a plasma-deposited protective coating comprising a substantially continuous, protective coating which conforms substantially to the surface of the stimulable phosphor. In a preferred embodiment, the coating has a thickness of between about 0.10 and about 1.0 .mu.m, and provides a thinner coating having greater sensitivity to radiation emitted from weak radioactive labels than conventional screen protective coatings, but with effective protection from moisture and physical damage.

Hollow fiber structures for culturing mammalian cells in an agitated media are disclosed. These hollow fibers have a cylindrical wall surrounding a lumen preferably open at opposite ends of the fiber and have a length along the axis parallel to the lumen of not more than 5 centimeters. Hollow fiber structures which have their exterior surface coated to prevent cell attachment and growth thereon are also disclosed.
