On January 4, 2012 we tested 1/4 teaspoon (1.25 grams) of potassium salt. Potassium is naturally radioactive. We performed this test to prove the graph software and geiger are capable of detecting
contamination. Below you will see two graphs. The first graph displays 3 hours of data. The potassium was placed in front of the counter at 13:05hrs. The data to the left of 13:05hrs is background radiation, to the right is the potassium sample. The second graph displays 900 minute's of data. The spike on the far right side of the graph is the potassium sample. As you can clearly see, the graph gives us the ability to visually see radiation. Furthermore, the equipment should be able to detect radiation in smaller quantities than those in the potassium.

On December 25, 2011 we tested a can of wild Alaskan pink salmon. The graph displays 3 hours of data. The salmon was placed in front of the geiger counter at 10:17pm (22:17hrs). The data to the left is background, to the right is the salmon.
Fast food/snack food test results
On January 9, 2012 we tested some instant noodles. The noodles were placed in front of the geiger counter at 11:45am. The graph below displays 3 hours of data. The data to the left of 11:45am is background radiation, to the right, the noodles.
On December 19, 2011 we tested a piece of pizza from a popular franchise. The graph below displays 3 hours of data. We placed the pizza sample in front of the geiger counter at 10:34pm (22:34hrs). The data to the left of the graph is background radiation, to the right is the pizza sample.
On December 13, 2011 we tested a piece of fried chicken from a popular franchise. The graph below shows the results of that test. The graph display's 3 hours of data. The chicken sample was placed in front of the geiger counter at 6:31pm(18:31hrs). The data to the left of 18:31 is background radiation, to the right is the chicken sample.
On December 7, 2011 we tested some sour cream & onion potato chips purchased from the local gas station. The potato chip test was conducted over a three hour period. The graph below shows 3 hours of data. The chips were placed in front of the geiger counter at 3:55pm(15:55hrs). The 90 min on the left is background radiation, to the right is the potato chip run. Overall the graph seems to be consistent, but the 20 count line does appear to show more graph spikes on the right side.

On December 2, 2011 we tested a cheeseburger from the local fast food restaurant. The cheeseburger test is shown below. We put the cheeseburger in front of the geiger counter at 5:17pm(17:17hrs). The data to the left is background radiation, to the right is the cheeseburger.

December 4, 2011 we performed a taco test. The taco was purchased from a popular franchise. The taco was placed in front of the geiger counter at 8:06pm(20:06hrs). The graph shows 3 hours of data. The data on the left side is background radiation, on the right is the taco test.
