How do you use the geiger muller tube to test for alpha?
Do you want to verify that a radioactive source emits ONLY alpha particles? If so, first measure the original count-rate, with no radioactive source, on the GM-tube. This is the background count-rate. Next, place the radioactive source near the GM-tube, and measure the new count-rate. Place a thin piece of paper between the GM-tube and the source. You will see that the count-rate dropped to the background count-rate. This is because all of the alpha particles are absorbed by the paper. If there were other types of radiation, like beta and gamma radiation, the count-rate wouldn't drop to the background count-rate.
