Simulation and Experimental Study of a Scintillation Fiber Detector of the Activities of ⁶³Ni-, ⁸⁹Sr- and ⁹⁰Sr-Based Radiation Sources

Abstract:

Results of a computer simulation and experimental study are presented for a fiber sensor based on a Saint-Gobain Crystals BSF-60 scintillation fiber which was used to measure the activities of sources of ionizing radiation. The simulation was based on the Monte Carlo method and the Geant4 software code and was applied to calculate the dependence of the number of beta-electrons entering a BSF-60 scintillation fiber on the activity of radiation sources based on ⁶³Ni, ⁸⁹Sr and ⁹⁰Sr isotopes. An experimental study of the sensitivity of the developed fiber sensor and the measuring system to beta-radiation of ⁶³Ni, ⁸⁹Sr and ⁹⁰Sr isotopes showed a high degree of compliance with the proposed model.
