Particle Camera MX-10 in Physics Education.

We present several applications of the particle camera MX-10 in different radiation environments, leading to strikingly different observed patterns and consequently particle composition as well as recorded dose. We describe the measurements of the radiation background, cosmic muons direction analysis and the detection of alpha particles in a natural cave. We focus on the analysis of tracks of highly ionizing particles aboard an airplane and compute the dose rate with altitude. We also comment briefly on a test in beams of particles at an accelerator. We discuss the problem of presenting sensitive results on radiation background levels in various environments to general public. Most of the experiments presented here were performed and analyzed by high-school students, confirming the application of the device not only for class-room demonstrations but also for science projects in physics and IT.
