An In-Phantom Radiation Detector
New England Journal of Medicine, 1961A SOLID, capable of detecting as well as measuring the amount of radiation and composed of several easily controlled organic molecules that can be prepared economically, has been devised for experimental and clinical applications.1 Owing to its characteristics it offers some completely new possibilities.

Spectrochimica Acta, 1953
Abstract The perfect radiation detector gives a signal for every quantum in the incident radiation. These quanta will arrive with random spacing. The resulting statistical uncertainty in the measurement of light will ordinarily appear as noise in the measuring process.

The Photo-Multiplier Radiation Detector
Review of Scientific Instruments, 1948The photo-multiplier radiation detector consists of a commercial multiplier photo-tube arranged to register the scintillations produced in a fluorescent screen by radiation quanta. The signal pulses thus obtained are large for alpha-particles and other high velocity ions, much weaker for x-rays, gamma-rays, and high velocity electrons.

Radiation damage in silicon detectors
La Rivista Del Nuovo Cimento Series 3, 1994This work presents an overview of the most important mechanisms of radiation damage in silicon detectors to be used for high energy experiments in LHC. The changes in the shallow concentration have been studied by thermally stimulated currents (TSC) after proton and neutron irradiation with fluences up to 10/sup 15/ cm/sup -2/ to investigate the role ...

Radiation Dosimetry with Scintillation Detectors
The British Journal of Radiology, 1953The theoretical considerations influencing the design of scintillation dosemeters are discussed. Details are given of simple and robust probe-type scintillation dosemeters suitable for clinical application. These instruments permit the measurement of dosage-rates due to X or γ radiation of 0·5 per hour and upwards, with a probe having an outside ...

Factors of Merit for Radiation Detectors*
Journal of the Optical Society of America, 1949In Part I, the need for a suitably defined factor of merit for comparing the sensitivity of different radiation detectors is explained (Section 1). Both the advantages and the very important limitations of such a factor of merit are discussed.In Section 2, separate factors of merit for Type I and Type II detectors are defined.

The Ultimate Sensitivity of Radiation Detectors
Journal of the Optical Society of America, 1947An upper limit is obtained for the sensitivity of any radiation detector which satisfies Lambert’s law and whose effective area is independent of the wave-length of the radiation. Expressions for the minimum detectable power are given by Eqs. (3.8) and (5.4).The treatment given is based on thermodynamics, and makes no use of statistical mechanics.
