| contents | Nuclear Fragmentation in Protontherapy Patrícia Rebello Mahir S. Hussein Física, Astronomía y Matemáticas The procedure followed by the Laborat´orio de Metrologia Nuclear (LMN) at the IPEN, in Sao Paulo, for thestandardization of the 45Ca is described. The activity measurement was carried out in a 4¼¯-° coincidencesystem, by the tracing method. The radionuclide chosen as the ¯-° emitting tracer nuclide was 60Co becauseof its end-point beta-ray energy which is close to 45Ca. Six sources were prepared using a 1:1 ratio (¯-pure and¯-°) dropped directly on the Collodion film, and other two solutions of 45Ca + 60Co were mixed previouslyusing a 1:1 and 1:2 ratio before making the radioactive sources. The activity of the solution was determined bythe extrapolation technique. The events were registered using a Time to Amplitude Converter (TAC) associatedwith a Multi-channel Analyzer. 2004 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46434562 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3A Vol.34 |
