Routine monthly test results

December 19, 2011 milk test
On December 19, 2011 we performed our routine monthly milk sample test. The graph below shows the results of that test. The graph displays 6 hours of data. The milk sample was placed in front of the geiger counter at 3:28pm(15:28hrs). The data to the left is background radiation, to the right is the milk sample.

Decenber 9, 2011 baby food test
On  December 9, 2011 we performed our monthly baby food test. The graphs below show the results of the test. The first graph displays 3 hours of data. We placed the baby food in front of the geiger counter at 1:40pm(13:40hrs). The data to the left of 1:40pm is background radiation, to the right is the baby food sample. The second graph show's 20 hours of data. To the far right of the graph is the baby food sample. The third graph is a rain sample collected on November 16, 2011. We showed this graph so everyone can see what a radioactive spike looks like.

Slightly radioactive rain

November 2011, mushroom test
On November 28, 2011 we tested portabella mushrooms for radioactive contamination. Keep in mind the test was conducted with a halogen-quenched uncompensated GM with a thin mica window 1.5-2.0 mg/cm2. This type of geiger is not sensitive enough to detect low level contamination, but will detect high levels of contamination. Furthermore, the mushroom was not dehydrated, which would further limit the radioactivity detected. The graph below shows the results of the test. The mushroom sample was placed in front of the geiger counter at 8pm (2000hrs). The data to the left of 8pm is background radiation, to the right is the mushroom sample.

November 2011 milk test 

We decided to perform a monthly milk test. Strontium 90 and other radionuclide's will end up in the milk of cows. The cows will graze in a field and eat contamination on the vegetation. The contamination will then concentrate in the milk.

After testing the milk We decided to perform a simmered milk test. We were not convinced the milk was uncontaminated after the first test. We simmered a half gallon of milk down into a paste and tested it. Below is the data from the simmered milk test. The graph shows 3 hours of data. The 90 minutes on the left is background, on the right is the milk sample.
