The effect of air pressure on the range of alpha particles
Alpha particles have a range of about 6cm or 7cm in air at normal atmospheric pressure. This is because the kinetic energy of the alpha particle is continually being transferred to air molecules due to collisions between the alpha particles and the air molecules.
Design an experiment to investigate how the range of alpha particles in air is affected by the air pressure. Name the alpha particle detector you would use. List the other apparatus that would be required and explain how you would use it in performing th experiment. Pay particular attention to any safety precautions which should be taken.

Change pressure using a valve system
A silicon based detector is usually used to detect ionized particles

No... that's the whole point of me asking
