An “optical-data model” is employed to evaluate energy loss per unit pathlength and inelastic mean free path for low-energy electrons and positrons (≲ 10 keV) from optical data on the medium of interest. Exchange between the incident electron a
This report provides both calculated estimates and measured values of exposure in air and tissue dose from external penetrating radiation at a distance of 1 m from uranium contamination on surfaces at the Oak Ridge Y-12 Plant, in support of the Y-12

The beta calibration factor for converting light output (on reading a thermoluminescent dosimeter) to shallow dose equivalent has been reexamined through theoretical calculations and experimental measurements. The results support the previously deter

Since the beginning of plant operations. almost all work with radioactive materials has involved isotopes associated with uranium, enriched or depleted in U[sup 235]. While limited quantities of isotopes of elements other than uranium are present, wo

Electron inelastic mean free paths and energy loss per unit pathlength for electrons in poly (methyl methacrylate) (PMMA) are calculated for electron energies below 10 keV. An insulator model is used to describe the interactions with valence electron

A model is described for evaluating energy loss per unit pathlength and inelastic mean free path for low-energy electrons (≲ 10 keV) from optical data on the medium of interest. Exchange between the incident electron and electrons in the medium is

A plasmon generated by a swift charged particle constitutes a coherent excitation about the particle track. We discuss the physics of the plasmon in condensed matter and its effects on electron transport in liquid water. Criteria for the existence of

Theoretical analysis of electron-target interactions requires knowledge of the electron inelastic mean free paths and the stopping powers of the medium. We provide stopping parameters for electrons with energies from ≈100 eV up to 10 keV, and calcu
