Abstract:

A tabulation of attenuation coefficients of X-rays and gamma rays from 0.01 to 100 Mev for 29 materials is presented. A summary of information on the probability of the basic interaction processes of photons with matter and a detailed analysis of experimental and theoretical evidence are included. Present information on the basic processes is adequate for many applications however, improved theory and additional experimental data are needed in certain areas. A comparison of calculated and experimental coefficients points up this need.
