Radioisotope applications in industrial process inspection and evaluation using gamma-ray emitters provide otherwise unavailable information. Offering alternative gamma-ray sources can support the technology by complementing sources’ availability and radiation safety. This work proposes to replace gamma-ray from radioisotopes with prompt gamma-ray from the interaction of neutrons with stable isotopes injected into the industrial process or with the structural material of the industrial process equipment. Monte Carlo N-Particle Transport Code (MCNP5) was used to simulate the irradiation of two-phase fl ow pipes by 252Cf neutron source. Two simulations were run for each pipe, with and without mixing the liquid phase with the stable isotope 157Gd. The detected gamma-ray spectra were analysed, and images of the two phases inside the pipes were produced. The images were compared to images obtained from simulations of gamma transmission measurement using 60Co. Furthermore, results for prompt gamma computed tomography (CT) were presented and discussed. The studies’ outcomes indicate the potential of prompt gamma-ray to carry out the sealed sources applications of gamma transmission measurements and imaging.

Radioactive sealed sources and radiotracer techniques are used to diagnose industrial process units. This work introduces a workspace to simulate four sealed sources and radiotracer applications, namely, gamma scanning of distillation columns, gamma scanning of pipes, gamma transmission tomography, and radiotracer fl ow rate measurements. The workspace was created in Geant4 Application for Tomographic Emission (GATE) simulation toolkit and was called Industrial Radioisotope Applications Virtual Laboratory. The fl exibility of GATE and the fact that it is an open-source software render it advantageous to radioisotope technology practitioners, educators, and students. The comparison of the simulation results with experimental results that are available in the literature showed the effectiveness of the virtual laboratory.

The paper summarises the 50-years long history of the development of research programmes related to the practical applications of radionuclides in various fields of the Polish economy. The changing trends of interest of the potential users are reflected in the research and development activities of the Radioisotope Centre POLATOM. In the 1960's and 1970's the main areas of activity were focused on the sealed sources and radiolabelled compounds for the investigation of industrial processes. The introduction to the routine practice of the RIA and the IRMA kits for hormonal in vitro diagnostics in the 70-ties and 80-ties resulted in the general availability of this diagnostic technique in Poland. The number of radioisotopes having the required radiation type, energy and half-life is steadily increasing due to the progress in irradiation facilities and in chemical separation processes. The need for modern radiopharmaceuticals, more specific and providing higher diagnostic and therapeutic potential as an alternative to other medical modalities is reflected in the research programmes carried out and implemented currently at the Radioisotope Centre POLATOM.
