The RADAK users' manual

RADAK is a program for calculating flux spectra from the output of multi-channel and single-channel neutron or γ-ray detectors. The output from several such detectors may be analysed simultaneously to produce a single-valued flux solution, and allowance may be made for the uncertainties in the detector response functions. The errors, including correlations, of the flux solution are estimated. This report outlines the facilities available, and gives full details of the input data required and the output produced. The Appendices describe two associated programs, PRC and NE213, which respectively provide the response functions of gas-filled proportional counters and organic liquid scintillators. (author)
