Description
This work aims to simulate the radioactive source, detector, detection electronics, and analog-to-digital converter system, generally used for the determination, in multichannel technology, of the energy spectrum of γ and β emitting sources. It is important to emphasize that the manipulation of radioactive sources by undergraduate students in Physics or Engineering can be a fearful or even dangerous practice. Furthermore, for some secondary or higher education institutions, obtaining authorization from the National Nuclear Energy Commission (CNEN) to obtain, transport, and store radioactive sources can become a bureaucratic and complex task. In contrast to the aforementioned limitations and difficulties, simulating radioactive sources from photons emitted by light-emitting diodes (LEDs), particularly IR LEDs, has the virtue of not being radiations visible to the naked eye, nor ionizing, which allows an adequate mimicry of radioactive sources.
