“…In general, in order to carry out a didactic experimental practice that reproduces the Bragg curve, it is necessary to use high-cost professional equipment [3], making it unfeasible in many educational institutions. Motivated by the importance of the Bragg curve, we propose in this work the construction of a low-cost ionization chamber detector inspired by Wenzel [4] and Bastos [5] that, with a low-intensity radioactive source, makes it possible to carry out an experiment to obtain the characteristic Bragg curve.…”
