The Pu/Be source is placed inside paraffin blocks (for slowing down the neutrons and shielding). A slide with a holder for the silver plate will push the plate inside the paraffin block close to the source. When the slide is withdrawn the silver plate will fall out of the holder (into your waiting hand).
Your supervise 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.
Perform five irradiations with the following times: 12, 24, 48, 72, 144 s and measure the resulting decay curves of the two silver isotopes.
It is important that you let the silver decay before you perform the subsequent irradiations.
