Software for automatic spectral analysis of radionuclides

Multichannel Analyzers are essential equipment in radioactive analysis laboratories since the measurement of the pulse height from a radiation detector has important information that can be used to qualify and quantify the radiation beam. This paper describes a set of computer codes which, in conjunction with an acquisition hardware for nuclear pulses, transforms a personal computer into a multichannel analyzer. The software searches peaks, calculates their area and corresponding energy and identifies the radiation source, by previous calibration in energy. The program also gets the on-line spectrum, working in either pre-adjusting time or pre-adjusting counting mode and makes the corrections due to the system dead time. There is a module for construction and list the radioisotope library. (author). 3 refs., 2 figs
