An extensive library of photon interaction coefficients has been developed by the Ontario Cancer Institute, Toronto, Ontario, Canada, based on the compilation of Plechaty, Cullen, and Howerton. In addition to partial cross section data, the following are given: mass attenuation coefficients, mass energy transfer coefficients, mass energy absorption coefficients, average energy transferred to electrons, average energy absorbed per interaction, and average stopping power of electrons. Partial interaction coefficients and absorption coefficients are useful in any radiation transport or other radiation analysis application.

The data from the Ontario Cancer Institute are given for 94 elements and 25 composite materials covering the energy range 1 KeV to 100 MeV. The reactions considered are coherent and incoherent scattering, photoelectric absorption, and pair production.

4. METHOD OF SOLUTION

The energy absorption coefficients were determined by the methods described by Cunningham and Johns.

8. RELATED AND AUXILIARY PROGRAMS

The FORTRAN 77 data retrieval programs are designed for use on minicomputers. The main data file,  containing tables for all materials, is converted to a direct access file by the RANDOM program. The retrieval program, READX, is used to locate the data for selected materials and output the data to a sequential file.
