Images Alpha Particle Spark Detector allows one to see the detection of alpha particles. It demonstrates the electronic detection of radioactive alpha particles. In addition by using a plain sheet of paper one can demonstrate the shielding of radioactive particles by an absorber.
This alpha particle spark detector utilizes a 8000 volt negatively-charged electrode and thin diameter copper wires connected to ground that are strung through the air approximately 0.1" above the electrode. When an alpha particle passes in-between the wire and the electrode it ionizes the air between. The high voltage potential between the wires and the electrode causes an avalanche effect that we see as an electrical discharge between the wires and the electrode.
This detector is only sensitive to alpha (α) particles, and will not detect beta(β), X-ray or gamma(γ) radiation.
Alpha particle source not included. Alpha particle sources must be purchased separately.
