Location is Something, or Is It?

 

This experiment is to check the horizontal (or vertical, if you wish) muon rate in various locations which have different amounts of apparent shielding.  You will keep the telescope in whatever orientation you decide (say, horizontal and aligned N-S) and vary the amount of material around it by choosing appropriate locations.

                                                                           

You should have one trial from outdoors where there are no buildings or hills nearby (you’ll need shelter, security, and electricity).  Another location might be inside a wooden frame building.  Still another might be a concrete and steel building with many walls between the telescope and the outside world. Then, perhaps you could seek out a basement or underground space where muons would have to come through truly large amounts of dense material to reach the detectors.  You might want to try varying the location in a systematic way, such as different floors of a tall building, or different distances from the exterior of a wide building, so that you could graph your results.

 

For each of the locations, calculate the count rate and uncertainty in the rate.

 

Try to account for any real differences in count rate. Differences are likely real when two rates differ by more than the square root of the sum of the squared uncertainties.
