          Abstract

          Este trabalho aborda conceitos associados à interação da radiação eletromagnética com a matéria, através de uma aplicação experimental de baixo custo, capaz de gerar imagens digitais comumente utilizadas em áreas de medicina nuclear, radiodiagnósticos, ciências ambientais, indústria, etc. Além de aproximar ao funcionamento básico de tecnologias inovadoras, esta prática também tem por objetivo permitir ao aluno compreender as leis físicas associadas, que normalmente são apresentadas nas disciplinas teóricas, mas que o aluno geralmente tem dificuldade de compreensão. O kit é baseado na detecção da radiação gama, abordando fenômenos associados a interação de fótons com a matéria, leis do inverso do quadrado da distância e de atenuação de um feixe de fótons, ângulo sólido e resolução de imagens.

          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.
