Measurement of photon mass attenuation coefficients of plutonium from 60 to 2615keV

Uncertainty of Plutonium Isotopic Measurements with Microcalorimeter and High-Purity Germanium Detectors

“…All X-ray line widths are assigned an uncertainty of 4% [21]. Mass attenuation coefficients are assigned an uncertainty of 2% [22], [23], [24]. An uncertainty of 2% is assigned to the relative emission rate of tin X-rays [25].…”

Using Mathematical Procedure to Compute the Attenuation Coefficient in Spectrometry Fields

“…When chemical composition of the samples is known, this coef icient can be calculated by using the photon cross sections data base [5]. There is one method for determining the linear attenuation coef icient under the assumption that the density of the sample in which a collimated narrow beam is used [6][7][8][9][10] is uniform. However, this method is dif icult to be carried out in a typical laboratory because of high radioactivity of sources prices and the requirement of a large space for the devices.…”

Measurement of X-ray mass attenuation coefficient of nickel around the K-edge using synchrotron radiation based X-ray absorption study

“…Fe (Z ¼26) and Cu (Z¼29) each showed one of the series of narrow peaks to be extending E20% above the theoretical values (Del Grande, 1986). Saloman et al (1988) and Hubbell (1994) pointed that differences exist between these compilations and they are of the order of 5-10% in the neighbourhood of 10 keV and below, rising to as much as 30% near the absorption edge. Gerward (1993) pointed that in the region near the edge discrepancies still exist between the theoretical and measured values.…”

“…Hence, in view of the above applications variety of experimental works have been performed using radioactive source to determine the mass attenuation values on the various types of materials such as elements and compounds (Hopkins, 1959; Contents lists available at ScienceDirect journal homepage: www.elsevier.com/locate/radphyschem Parthasaradhi and Hasen, 1974;Kane et al, 1977;Gerward, 1982Gerward, , 1983Gowda and Powers, 1985;Rettschlag et al, 2007;Umesh et al, 1981Umesh et al, , 1982Sarma et al, 1982;Nageswara Rao et al, 1984;Turgut et al, 2004Turgut et al, , 2007Icelli and Erzeneoglu, 2004;Sharanabasappa et al, 2009), tissue equivalent compounds (Parthasaradhi et al, 1992), alloys (El-Kateb et al, 2000), building materials (Alam et al, 2001;Akkurt et al, 2010) etc., at different photon energies.…”

“…Since many years significant photon attenuation measurements, calculations and compilations in elements have been published (Grodstein, 1957;Wiedenbeek, 1962;McCrary et al, 1967;Hubbell, 1969Hubbell, , 1971Hubbell, , 1982Conner et al, 1970;Storm and Israel, 1970;Pratt et al, 1973;Veigele, 1973;Henke et al, 1982;Saloman et al, 1988). However the data's on X-ray attenuation measurements using radioactive source in elements near the absorption edge seems to be very limited and in many cases it was the extrapolation method which was used to measure attenuation values near the edge Sivasankar Rao et al, 1977;Chandra lingam et al, 1983;Krishna Rao et al, 1984;Deutsch and Hart, 1986;Kefi et al, 1987;Kerur et al, 1993).…”
