Abstract
The invention relates to a device for capturing ionizing radiation, in which a substrate which is provided with a phosphor layer is accommodated in a housing. To simplify the device and to ensure a high light yield, the invention provides that a means for buffering the atmospheric humidity is accommodated in the housing.
Claims9
A device for capturing ionizing radiation, in which a substrate which is provided with a phosphor layer is accommodated in a housing, characterized in that a means for buffering the atmospheric humidity is accommodated in the housing.
The device as claimed in one of the preceding claims, in which the housing is substantially produced from a water-vapor-impermeable material, preferably from glass, metal or plastic.
The device as claimed in one of the preceding claims, in which the drying buffer contains a saturated solution of a further alkali metal halide.
The device as claimed in one of the preceding claims, in which the alkali metal halide and the further alkali metal halide have the same composition.
The device as claimed in one of the preceding claims, in which the drying buffer contains silica gel.
The device as claimed in one of the preceding claims, in which a fresh-air access provided on the housing is designed in such a way that fresh air which enters the housing is passed via the drying buffer.
The device as claimed in one of the preceding claims, in which the drying buffer can be used to set a constant atmospheric humidity in the range from 50 to 60%, preferably of 55%, in the housing.
