Particle Detectors Concept

Demonstrates detection of ionizing radiation with a Geiger-Müller counter. Students hear the random clicking of decay events, observe the difference between background and source count rates, and see that radioactive …

Demonstrates semiconductor radiation detection using a surface barrier detector. Students learn how ionizing radiation creates electron-hole pairs in silicon, producing electrical pulses proportional to particle energy, and why solid-state detectors …

Charged particles leave visible condensation trails in supersaturated alcohol vapor, allowing direct observation of alpha particles, beta particles, and cosmic ray muons. Students see how particle mass, charge, and energy …
