Solid State Radiation Detector - Physics Demonstrations - Solid State Radiation Detector | Physics Undergraduate Labs

Log in to reserve this demo

Handle radioactive sources according to your institution's radiation safety protocols. Use sealed sources only, maintain ALARA principles (As Low As Reasonably Achievable), limit exposure time, and store sources in approved containers when not in use. Verify that sources are within exempt quantity limits or that you have appropriate licensing.

Purpose

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 offer superior energy resolution compared to gas-filled detectors.
