There are no outstanding safety concerns for this lab.
A detailed set up can be found in Prof. Gold's lab manual. This lab was already set up when Sebastian and I chose to do this experiment, so I am unfamiliar with the details. Basically, a device which detects radiation is connected to a computer with software set up such that the number of detected 'events' are recorded over multiple intervals. These observations are what make up the data to be analyzed for this lab.
The process of taking data for this lab is actually quite simple. Under the settings, Sebastian and I selected MCS mode. Under the settings menu, we set voltage to 1000V, number of bins to 256. These settings are held constant. The variable setting is the time interval for each bin. We chose 10ms, 20ms, 40ms, 80ms, 100ms, 200ms, 400ms, 1s and 2s intervals for our trials. With the correct settings selected, simply tell the computer to start collecting data. After this, wait and then proceed to the next trial. Save the runs as .cvs files, which can be opened in various applications for analysis.
Calculations and Results
The raw data and relevant equations can be found here, under the 'Data and Calculations' section.
