COMMUNITY RADIATION MONITORING REPORT
Dell Sullivan, Manager of the Community Radiation Monitoring Station in
Alamo, NV reported the results of the radiation measurementsat this station
forthe period July 11 to July 20, 1988. The average gammaradiation exposure
rate recorded by a Pressurized [on Chamber at this station was 13.0
microroentgens* per hour as shown on the chart.

The averages of the 16 Community Monitoring Stations operated for the
Environmental Protection Agency, Department of Energy and the Desert
Research Institute varied from 6.2 microroentgens per hour at Las Vegas, NV
to 20.2 microroentgensper hourat Austin, NV. All of the rates for the past week
were within the normal backgroundrangefor the United States as shown on the
accompanying chart.
Environmental radiation exposure rates vary with
altitude and natural radioactivity in the soil. Additional information and
detailed data obtained from Community Radiation Monitoring Network
Stations, including an annual summary of the results from all monitoring
aroundthe NevadaTest Site, can be obtained from Mr. Sullivan (702) 725-3544
or by calling Charles F, Costa at the EPA in Las Vegas (702) 798-2305.
“The roentgen is a measure of exposure to X or gamma radiation. A microroentgen is 1
millionth of a roentgen. For comparison, one chest x-ray results in an exposure of 10,000 to
20,000 microroentgens.
