NIST Standard Reference Database 126 Last Update to Data Content: July 2004 NISTIR 5632 DOI: Tables of X-Ray Mass Attenuation Coefficients and Mass Energy-Absorption Coefficients from 1 keV to 20 MeV for Elements Z = 1 to 92 and 48 Additional Substances of Dosimetric Interest* J. Hubbell + and Radiation Physics Division, PML, NIST © 1989, 1990, 1996 copyright by the U.S. Secretary of Commerce on behalf of the United States of America. All rights reserved. NIST reserves the right to charge for these data in the future. Abstract Tables and graphs of the photon mass attenuation coefficient μ/ ρ and the mass energy-absorption coefficient μ en/ ρ are presented for all of the elements Z = 1 to 92, and for 48 compounds and mixtures of radiological interest.

The tables cover energies of the photon (x-ray, gamma ray, bremsstrahlung) from 1 keV to 20 MeV. The μ/ ρ values are taken from the current photon interaction database at the National Institute of Standards and Technology, and the μ en/ ρ values are based on the new calculations by Seltzer described in Radiation Research 136, 147 (1993). These tables of μ/ ρ and μ en/ ρ replace and extend the tables given by Hubbell in the International Journal of Applied Radiation and Isotopes 33, 1269 (1982). Table of Contents • • Material constants for elemental media. Material constants and composition for compounds and mixtures.

Values of the mass attenuation coefficient and the mass energy-absorption coefficient as a function of photon energy, for: [Data] elemental media. [Data] compounds and mixtures. • • • *Work supported by the of NIST. +Work carried out for NIST under contract 43NANB412756.

The attenuation properties of these glasses with different concentrations of PbO (20% - 70%) have been investigated at photon energies 662, 1173, 1332 and 2614 keV.

The data arriving through serial communication should be transferred to an excel sheet/database. The excel sheet/database should display a count for each pushbutton. I have 4 important question areas: Which microcontroller should i use? (I have experience with arduino development platform). The purpose of this article is to demonstrate how you can perform serial port communication in the VBA (Visual Basic Applications – script editor included in any typical Microsoft Excel distribution) but without using the MSComm control or any other third party add-on or ActiveX. Vba for excel serial communication with arduino microcontroller. I'm trying to control an Arduino via Excel VBA using the MSCOMM control The following sketch accepts serial input, and controls the brightness of a led It works fine when data is entered via a serial monitor. Maurizio @ dev.emcelettronica.com discuss how we can do serial communication in Excel environment. Serial Port Communication in Excel (VBA).

The optical absorption spectra of some glass samples have been measured from 200 to 1100 nm before and after g-ray irradiation. The analyses of these spectra have been interpreted and discussed.
