WebTables of photon mass attenuation coefficients are essential in radiological physics, radiography (for medical and security purposes), dosimetry, diffraction, interferometry, crystallography, and other branches of physics. The photons can be in form of X-rays, gamma rays, and bremsstrahlung . WebData treatment. The UV/Vis spectra collected are taken mainly in the liquid phase (this reflects the nature of the literature the spectra are abstracted from). Consequently the data on the solvent used are included. In some rare cases when data published were obtained in the gas or vapor phases just such spectra were included in the collection. importance of fiscal management in school
