Radiation Education Kit


The Radiation Education Kit is a setup of radiation camera, radioisotope sources, and accessories to better understand nuclear and particle physics. The kit brings the latest CERN technology to classrooms and lets the students discover the invisible world of radiation. The same technology, Advacam’s MiniPIX, is being used by NASA to monitor radiation on the International Space Station.


Advacam’s Minipix EDU comes with Pixet Basic software that provides a simple interface for analyzing radiation. The accessories and experiments are designed to help students better understand muons, alpha, beta, gamma, and other particles.

The kit is extensible beyond the provided experiments. The translation stage is a standard platform with dimensions provided. Thus, you may come up with your own ideas and perform novel experiments. Share the experiments on the online platform and discover the ideas from other creative people like you. The online community also helps with technical issues and serves as a platform for Q&As.
