Abstract

Abstract: An inter-comparison of three boron determination techniques was carried out between laboratories from INFN-University of Pavia (Italy) and CNEA (Argentina): alpha spectrometry (alpha-spect), neutron capture radiography (NCR) and quantitative autoradiography (QTA). Samples of different nature were analysed: liquid standards, liver homogenates and tissue samples from different treatment protocols. The techniques showed a good agreement in a concentration range of interest in BNCT (1–100 ppm), thus demonstrating their applicability as precise methods to quantify boron and determine its distribution in tissues. Highlights: Intensive BNCT research collaboration is ongoing between Argentina and Pavia BNCT groups. An inter-comparison of three boron determination nuclear techniques: alpha-spect, NCR and QTA. Real tissue samples were used together with a variety of boron compounds. Results showed a good agreement and no statistical discrepancy for liquid and tissue samples. This work contributed to a better understanding of the issues related to each technique.
