NISTX Calculator You can use this application to quickly calculate and compare photon attenuation coefficients for any material from the NIST website. Just select the number of materials you wish to view and a photon energy and the corresponding information will be displayed below. If only one material is chosen, the full coefficient table is provided, otherwise a comparison of materials at the specified energy is provided. This application is built on the NistPad project .
