Abstract: Phosphor-containing panels or screens have improved resistance to yellowing and image defects by the incorporation of a primary or secondary amine having a pKa of 8.5 or more and a molecular weight of less than 10,000 daltons into the phosphor layer or an overcoat layer. A peroxide scavenger can also be present to further improve stability of the phosphor panel. The phosphors are preferably storage phosphors containing iodine. This phosphor panels can be prepared using non-peroxide-generating organic solvents for further stabilization.

Abstract: A dosimeter and method of measuring an absorbed dose of ionizing radiation using the dosimeter comprising at least one first region containing a radiation sensitive material, and a second region containing an identification mark are described, wherein the method includes the steps of: providing a first region including a radiation sensitive material capable of measuring an absorbed dose of ionizing radiation; providing a second region bearing an identification mark; exposing at least the first region to a dose of ionizing radiation; and reading the signal from the first region. The dosimeter can be used to track location and irradiation of an associated good.

Abstract: A method of measuring an absorbed dose of ionizing radiation using a measuring device that bears an integral identification mark, comprising the steps of: providing a support; disposing on the support a first region capable of measuring an absorbed dose of ionizing radiation; disposing on the support a second region that bears integral identification mark; exposing at least the first region to a dose of ionizing radiation; and reading the signal from the first region.

Abstract: An apparatus and method for removing stored energy from a storage phosphor screen in which a radiation image was recorded and then read by collecting stimulated emission from the phosphor sheet. The method is accomplished by directing onto the storage phosphor sheet an erasing light having substantially no light of a wavelength of shorter than 410 nm. The apparatus of an erasing light is provided by coating a light source with a yellow dye.

Abstract: A radiographic imaging assembly comprises a radiographic silver halide film and a single fluorescent intensifying screen that has protective overcoat that comprises a miscible blend of a first polymer that is poly(vinylidene fluoride-co-tetrafluoroethylene) and a second polymer that is a poly(alkyl acrylate or methacrylate). This imaging assembly is particularly useful for mammography or imaging or other soft tissues.

Abstract: A dosimeter comprising: a support; at least one first region disposed on said support, the region containing amino acid and a binder; and at least one second region disposed on said support; wherein the first region is capable of measuring an absorbed dose of ionizing radiation and the second region bears an identification mark.

Abstract: The present invention is a method of producing an imaging support which includes providing a support, simultaneously coating on a side of the support; a transparent magnetic recording layer comprising magnetic particles, a polymeric binder and an organic solvent, and a lubricating overcoat layer farthest from the support, the lubricating overcoat layer comprising wax particles having a size from 0.01 .mu.m to 0.5 .mu.m, and an organic solvent; and drying the magnetic recording layer and the lubricating overcoat layer.

Abstract: A modem having a transmitter portion including a first modulator connected to receive audio frequency signals and supplying an output signal through a single sideband filter to a second modulator providing an output signal at a unique channel frequency, a receiver portion including a first demodulator connected to receive transmitted signals and supplying an output signal to a second demodulator through a single sideband filter with the second demodulator providing audio frequency output signals, a carrier switch supplying a small amount of the carrier to the second modulator during operation of the transmitter and a carrier level switch associated with the carrier switch for supplying the carrier at high and low levels, and a crystal controlled channel oscillator connected to the second modulator of the transmitter portion and the first demodulator of the receiver portion with removable, plugin crystals connected thereto for controlling the channel frequency of the modem.
