Two thermal methods to measure the energy fluence of a brief exposure of diagnostic x rays
(1992-07-03)
This paper describes two simple thermal methods for measuring the energy fluence in J/cm 2 from a diagnostic x-ray exposure. Both detectors absorb essentially 100% of the radiation and give a signal that is directly ...

Doping of polyaniline and derivatives induced by X-ray radiation
(1997-01-01)
Thin films of chemically synthesized polyaniline and poly(o-methoxyaniline) were exposed to ionizing X-ray radiation and characterized by radiation induced conductivity measurements, ultraviolet-visible spectroscopy, ...
Measurement of orthovoltage X-ray intensity with a lithium niobate transducer
(2009-12-01)
A microcontrolled instrument for measuring the energy fluence rate (or intensity) of X-ray pulses in the orthovoltage range of 120 to 300 kV is described. The prototype instrument consists of a pyroelectric sensor, a ...

Background radiation in inelastic X-ray scattering and X-ray emission spectroscopy. A study for Johann-type spectrometers
(Elsevier Science, 2018-06-21)
A study of the background radiation in inelastic X-ray scattering (IXS) and X-ray emission spectroscopy (XES) based on an analytical model is presented. The calculation model considers spurious radiation originated from ...
Radiative models for jets in X-ray binaries
(Paideia, 2013-06)
In this work we develop a lepto-hadronic model for the electromagnetic radiation from jets in microquasars with low-mass companion stars. We present general results as well as applications to some specific systems, and ...
Monte Carlo simulation applied in total reflection X-ray fluorescence: Preliminary results
(2013-05-20)
The X-ray Fluorescence (XRF) analysis is a technique for the qualitative and quantitative determination of chemical constituents in a sample. This method is based on detection of the characteristic radiation intensities ...
