A brief but very effective description on the basic formation of detector crystal and creation of signal pulse has been presented here. This article is furnished in such a way that the contents find useful and interesting to physics and electronics students, educators, and also researchers who are generally reading outside their specialties to broaden their understanding of physics and to expand and enhance their pedagogical toolkits at the undergraduate and graduate levels. 06 2011 42 46 10.14331/ijfps.2011.330011 https://www.fundamentaljournals.com/index.php/ijfps/article/view/12
