摘要： An opaque, generally flat flexible cassette is provided which receives and holds a storage phosphor screen while the screen is radiographed. The cassette has sufficient flexibility to be wrapped around an object to be radiographed. The cassette has a light-tight sealing device at or near its open end. The sealing device allows the cassette to be placed in either an open position for receiving or discharging the storage phosphor screen, or a closed position for holding the imaging storage medium therein during radiographing and transport. The cassette is designed so that the storage phosphor screen is discharged from the cassette without being physically handled by a person or being exposed to ambient light.

摘要： Methods and apparatus for rapidly removing stored energy from (i.e., erasing) a reusable photostimulable storage phosphor screen use a first source of electromagnetic radiation which primarily outputs a wavelength or wavelengths of about 577 nanometers to about 597 nanometers, and a second source of electromagnetic radiation which primarily outputs a wavelength or wavelengths in the infrared region. Exposure to the second source of radiation may occur either after, or simultaneously with, exposure to the first source of radiation. During exposure to the first source of electromagnetic energy, ultraviolet radiation is filtered out so that none reaches the phosphor screen, or a first source is selected which does not output substantially any ultraviolet radiation. The first source of electromagnetic radiation erases the phosphor screen to a homogenized quasi-erased state. The second source of electromagnetic radiation erases the phosphor screen from the homogenized quasi-erased state to a fully or nearly fully erased state. The first source of electromagnetic radiation may be a sodium vapor lamp which also functions to remove residual images. Residual images may also be removed by exposing the phosphor screen to a source of electromagnetic radiation which outputs a wavelength or wavelengths including at least one of infrared and near-infrared, and a reduced amount of charging wavelengths. The process may include filtering any visible light having a wavelength below red light emitted from the second source of radiation.

The phosphor screen may also comprise a black, infrared-absorbing substrate with the phosphor layer coated on the substrate. The phosphor powder is formed by preparing a phosphor composition, sintering the composition to form ingots, grinding the ingots to form a powder wherein a substantial amount of particles in the powder have a particle size of greater than 0 and less than about 5 microns, reactivating the powder in an inert atmosphere to a temperature of from about 500° C. to about 550° C., preparing a suspension of the powder and a nonreactive organic solvent, mixing the suspension to separate particles of the powder which partially fuse during reactivation and to break up large agglomerates of the powder in the suspension, decanting the suspension to at least partially separate the nonreactive inorganic solvent and the powder, and drying the powder to form the phosphor powder.

The material is first formed in bulk with cerium sulfide, cerium oxide, or cerium, and lithium fluoride. The material is applied by physical vapor deposition in a relatively thin film to the substrate, and then at least the luminescent material is subjected to a high temperature for a period of time to effect recrystallization and activation of the material, such that the material acquires luminescent characteristics.

摘要： A fiber optic dosimeter in which an electron trapping material is held in a probe on the tip of an optical fiber. The probe is placed in a region with the radiation to be measured, and the opposite end of the optical fiber, from which radiation readings are measured, is placed in a location remote from the radiation source. When radiation impinges upon the electron trapping material, electrons in the material are raised to a higher state where they are trapped and stay indefinitely. When infrared light strikes the material, the stored electrons are released from their traps and, upon falling to a lower energy level, emit visible light which can be detected and measured. Thus, to measure the amount of ambient radiation, the electron trapping material is stimulated with infrared light from an infrared source at the opposite end of the optical fiber. This infrared stimulation releases trapped electrons and causes the emission of visible light, at least a portion of which is collected and directed back down the optical fiber to the visible light detector, where it is converted into an electrical signal and measured. The infrared stimulation is modulated to allow for measurement of background fluorescence during radiation exposure when infrared stimulation is not applied. This background fluorescence is then substracted from the gross signal under infrared stimulation to yield a signal which changes linearly with radiation input.
摘要翻译： 一种光电剂量计，其中电子捕获材料保持在光纤尖端的探针中。 将探针放置在具有要测量的辐射的区域中，并且将测量辐射读数的光纤的相对端放置在远离辐射源的位置。 当辐射照射到电子俘获材料上时，材料中的电子被升高到更高的状态，在这种状态下它们被捕获并无限期地保持。 当红外光照射材料时，所存储的电子从其陷阱中释放出来，并在下降到较低的能量水平时发出可被检测和测量的可见光。 因此，为了测量环境辐射的量，电子捕获材料用来自光纤相对端的红外源的红外光刺激。 这种红外线刺激释放被捕获的电子并引起可见光的发射，其中至少一部分被收集并且被引导回到光纤到可见光检测器，在那里被转换成电信号并被测量。 调制红外刺激，以便在不施加红外刺激时在辐射暴露期间测量背景荧光。 然后在红外线刺激下，将该背景荧光从总信号中减去，以产生随辐射输入线性变化的信号。

摘要： In a preferred embodiment, a radioluminescent lamp having a glass face plate with a plurality of parallel planar light guides, each preferably having a transparent glass, sapphire or quartz base member, disposed perpendicularly with respect to the glass face plate and coated on both sides with a thin film of radioluminescent phosphor material. The plates are mounted in a sealed envelope filled with tritium gas, the radioactive decay of the tritium causing the phosphor to luminesce. The phosphor material and all but one of the edges of each light guide are overcoated with a reflective material, such as aluminum, to guide the generated light to a single edge of the light guide, which edge is adjacent the glass face plate. The phosphor is preferably a calcium sulfide-based material forming a continuous, binder-free layer on the transparent base member. The resulting structure has a high phosphor-surface-area to tritium-gas-volume ratio and directional light guiding, yielding a substantially higher output light density than conventional radioluminescent lamps.
