ISOCS (In Situ Object Counting System) is the in situ gamma spectroscopy system used in a wide variety of measurement applications by ENEA laboratory. The gamma radiation detector is a BEGe (Broad Energy Germanium). The wide squat shape detector (liquid nitrogen cooled) offers high resolution, good sensitivity with short counting time and high efficiency also for low energy gamma rays. ISOCS is battery operated system (with modular shields and cart) which provides traditional spectra of counts vs gamma energy. The most important improvement of ISOCS system is the capability to obtain radionuclide activity by applying predefined geometry templates in the analysis software: defining the template, the user obtains an evaluation of the overall efficiency curve without the need of experimental calibration. However, the measurement configuration have to be defined and reproduced by user with good accuracy, even if, because of practical problems, this is not always allowed. Thus ISOCS can provide quick and real time information on the radionuclides assayed but in some real situation it is more suitable for qualitative than quantitative gamma activity measurement. This paper presents the results obtained at ENEA laboratory using ISOCS with certified gamma sources located in known matrices in real configurations but not easily reproducible. The aim of this work is to show the capability of this system in some stressed situation and to give a potential technical procedure to obtain reliable results. Copyright © 2005 by ASME.
