In summary, we have found the levels of fallout Cesium 137 in persons who
live near the Nevada Test Site to be similar to the levels in persons in Salt
Lake City.
While the average level seems slightly higher for Utah than the
rest of the United States this level
is not alarming, being only about 1/1000
