This work addresses concepts associated with the interaction of electromagnetic radiation with matter, through a low cost experimental application able to generate digital images commonly used in nuclear medicine, radiodiagnostics, environmental science, industry, etc. Besides approaching the basic concepts of innovative technologies, this practice also aims to enable students to understand the physical laws associated, which are usually presented in theoretical subjects, but students often have difficulty understanding. The kit is based on the gamma detection, addressing phenomena associated with the interaction of photons with matter, laws of the inverse square and attenuation of photons, solid angle and imaging resolution.
Keywords:
Interaction of photons with matter; gamma detection; Geiger-Müller counter; imaging
