ABSTRACT:
A stimulable phosphor sheet comprises an energy distribution separating layer, which contains a heavy metal compound capable of absorbing low energy components of radiation, and stimulable phosphor layers, which are overlaid respectively on the two surfaces of the energy distribution separating layer. When each of the stimulable phosphor layers is exposed to stimulating rays, it emits light in proportion to the amount of energy stored thereon during its exposure to radiation. The energy distribution separating layer is colored with a coloring material, which has characteristics such that it may transmit the stimulating rays and may absorb the light emitted by each of the stimulable phosphor layers.
