Gamma ray detection: building a didactic proposal

Abstract A simple and economic scintillator kit in combination with a computer-based oscilloscope was used to develop learning experience, comprised of set activities introduce students an interactive way the physics gamma-ray detection. The proposal for secondary school university is built by means frequent on-the-fly formative assessment collect difficulties ways overcome them. Internal decays Lutetium–yttrium oxyorthosilicate (LYSO) crystals already present are as sources gamma rays, so no external were needed. In addition, use LYSO offers reason discuss coincidence measurements, because inherent beta background internal decay, which can be at least partially removed measurements. goal experience how detection actually done, discussing involved, motivated current frontline research on bursts.
