Drew RasmussenChemistry 112 LabKatri TruhlerMay 5, 2011Radiation Intensity Report FormA.Research Questions:a.Which equation matches the graph of the Beta Emitter?b.What is the value of n from equation 2? (Slope of the line in graph 2).B.Data and Results:a.The Emitters are a red disc with a special core of some kind, and a foil covering on one side. The sensor is a black box with a bronze colored screen over the most sensitive part. This is to be lined up with the emitter disc when measuring counts. The background count of the room is 32, this will be used to make sure that the counts we measured is only pertaining to that emitted by the disc and not the background radiation in the class room.b.Part 1.b.i.Background Count: 32 CountsTable 1.0 Layers of Cardboard vs. Raw and Corrected Counts (Beta Emitter, pg. 26)Layers of CardboardRaw CountCorrected Count0 (N0)3523201 290258222519331771454162130514611461158371269481259399563109967*Excluding (from graph) data from 6 and 10 layers of cardboard because the number of counts increased when it should have decreased.
