The Pu/Be source is placed inside parafin blocks (for slowing down the neutrons and shielding). A slide with a holder for the silver plate will push the plate inside the parafin block close to the source. When the slide is witdrawn the silver plate will fall out of the holder (into your waiting hand).

Your superviser will operate the slide and you should catch the silver plate after the required irradiation time and at the same time start your stopwatch.

You then run as fast as possible (STRAFAP - STudents Running As Fast As Possible) but carefully to your detector with the source.
