The International Journal of Applied Radiation and Isotopes, 1982
Current dose measuring practices in the diagnostic and therapeutic use of radiation are reviewed. Radiation doses typically received by patients from diagnostic X-ray studies, including mammography and computerized axial tomography, are presented. Modern-day radiation therapy, both with conventional photons and with electrons and high-LET particles ...

The Dosimetry of Beta Radiations
Radiology, 1954With uniform distributions of beta emitters in large volumes dosimetry is relatively simple, and has been adequately treated by various authors (1, 2). The dosimetry of small or non-uniform sources, on the other hand, has received little attention. It is with the physics aspects of this problem that the present paper is concerned.

PLASTIC SCINTILLATOR FOR RADIATION DOSIMETRY
Radiation Protection Dosimetry, 2015Inorganic scintillators, composed of high-atomic-number materials such as the CsI(Tl) scintillator, are commonly used in commercially available a silicon diode and a scintillator embedded indirect-type electronic personal dosimeters because the light yield of the inorganic scintillator is higher than that of an organic scintillator.

Radiation Dosimetry by Transparent Plastics
Radiation Research, 1958The radiation-induced ultraviolet absorption in transparent plastics has been investigated in detail and found to be a convenient, rapid, inexpensive, and accurate method of measuring radiation doses between 10/sup 5/ and 2 x 10/sup 8/ rads. In methyl methacrylate (Perspex) the change in optical density at 2920 A is a linear function of the dose, up to

Advanced materials in radiation dosimetry
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2002Abstract High band-gap semiconductor materials can represent good alternatives to silicon in relative dosimetry. Schottky diodes made with epitaxial n-type 4 H SiC and Chemical Vapor Deposited diamond films with ohmic contacts have been exposed to a 60 Co γ-source, 20 MeV electrons and 6 MV X photons from a linear accelerator to test the current ...

Recent controversy in radiation dosimetry
European Journal of Nuclear Medicine, 1993The correspondence between Drs. Macleod and Kemp [1] and Drs. Johansson et al. [2] in this issue is an example of the controversy that has arisen over use of the quantities effective dose equivalent (EDE) [3] and effective dose (E) [4]. Johansson et al. correctly point out the interpretations of these quantities, as well as their intended applications.

Radiation dosimetry with dyed cellophane
The International Journal of Applied Radiation and Isotopes, 1963Abstract Bleaching of dyed cellophane has been used a method of electron and γ-dosimetry in the Mrad range. We have investigated the response over a wider range of doses and compared the changes with those produced by α-irradiation. No consistent difference was found between gamma and electrons indicating that the dose rate is not an important factor.

Technologies for retrospective radiation dosimetry
Radiation Protection DosimetryAbstract Radiation dosimetry is an important task for assessing the biological damages created in human being due to ionising radiation exposure. Ionising radiation being invisible and beyond the perception of human natural sensors, the dosimetry equipments/systems are the utmost requirement for its measurement. Retrospective measurement
