TLDR
The use of radiochromic dye films for electron dosimetry has been extended to absorbers with atomic numbers in the range 13–50 and it is demonstrated that the use of the constant stopping-power ratio gives depth-dose distributions that differ by no more than 1–2 per cent from the results obtained with the more rigorously evaluated stopping- power ratios.About:

Low energy scanned electron-beam dose distributions in thin layers
TL;DR: In this article, the authors used radiochromic dye film dosimeters calibrated by means of calorimetry to determine absorbed-dose distributions due to low-energy scanned electron beam penetrations in moderately thin coatings and laminar media.
Journal ArticleDOI
Electron Depth-Dose Distribution Measurements in Two-Layer Slab Absorbers
TL;DR: An investigation of stopping-power ratio evaluation methods based on the treatment of the film dosimeter as a nonperturbing cavity demonstrated that a constant value could be used for each material in a two-layer absorber independent of the thickness of each layer.
Journal ArticleDOI
Energy deposition by electron, bremsstrahlung, and 60Co gamma-ray beams in multi-layer media
TL;DR: In this paper, the authors present illustrative applications of the Monte Carlo code ZTRAN, which treats the penetration and diffusion of electrons and photons in targets consisting of multiple layers of different materials.
Journal ArticleDOI
Absolute Measurement of Low Energy Electron Deposition Profiles in Semi-Infinite Geometries
TL;DR: In this paper, two different techniques have been used to measure absolute electron energy deposition profiles in semi-infinite geometries: ionization chamber and magnetometer-based methods.

Distribution of Ionization in Materials Irradiated by Two and Three Million‐Volt Cathode Rays
TL;DR: In this article, the distribution of ionization in depth of aluminum produced by steady beams of two and three million-volt electrons was investigated. And the effect on this transverse distribution of additional aluminum scattering foils, and a practical method of cathode-ray dosage computation were given.

M. J. Berger,S. M. Seltzer +1 more
TL;DR: Information is presented on the penetration of high-energy electrons into a water phantom with particular reference to the following topics: energy and charge deposition; electron flux (differential in energy), including primary and secondary electrons down to a spectral energy of 400 ev; and distribution of delta-ray track ends.
