Question

For today’s lab you will have three radiation sources available. These are Polonium 210, Strontium 90 and Cobalt 60. What type of radiation do these three sources emit, and what are the half-lives of the three sources (you may have to do a search for the half-life information).

For Experiment C you will be changing the distance between a radiation source and a detector. How do you expect the count rate to change as a function of distance?

For Experiment D you will be investigating count statistics. For the situation in which there are a large number of radiation counts in a sample, and you take many samples in which the count varies in a regular statistical pattern, what do you expect the width of the histogram to be compared to the number of counts at the center of the distribution?
