Nuclear reactors emit small amounts of radioactive elements. Estimate your yearly dose from the most common sources of ionizing radiation with this interactive online dose calculator. Radiation Sources and Doses Sources of radiation radiation Energy given off as either particles or rays. Sierra Nevada : Granites containing high uranium, particularly in east-central California, show as red areas. The figure below shows the concentrations of uranium. Appalachian Mountains : Granites contain elevated uranium, particularly in fault zones. The map below shows a ternary map of the gamma-ray data where the uranium data are plotted as shades of cyan, potassium as shades of magenta, and thorium as shades of yellow. Naturally occurring radioactive minerals in the ground, soil, and water produce background radiation. The numbers represent radiation Counts per Minuteabbreviated CPMand under normal conditions, quantify the level of background radiationi.
Map of Potassium Concentrations. The figure below shows the concentrations of potassium. Click here to view a full-resolution version of the.
Map of Natural Radioactivity in the United States While this terrestrial radiation should not concern you too much, it is good to be aware of its. The amount of radiation absorbed by a person is measured in dose. A dose Terrestrial radiation levels vary by location, but areas with higher.
Referring to the Map Legend at the bottom left corner of the map, locate Monitoring Stations around the country that are contributing radiation data to this map as you read this, and watch the numbers on those monitoring stations update as frequently as every minute your browser will automatically refresh.

A growing number of Radiation Monitoring Stations across the country and worldusing various models of Geiger Countersupload their Radiation Count data in real time to their computer using a Data Cableand then over the Internet to this web site, all of this accomplished through GeigerGraph for Networks software.
Essentially all air contains radonwhich is responsible for most of the dose that Americans receive each year from natural background sources. The figure below shows the concentrations of potassium.
Thus it has a high radon potential. The Black Hills : A core of granites and metamorphic rocks high in radioactivity is surrounded by less radioactive sedimentary rocks and gives a distinctive pattern.
Terrestrial radiation, for the purpose of the table above, only includes He and his neighbours in Boyertown, Pennsylvania, United States may hold the record . Regular Radiation measurement is carried out at multiple levels.
can come from as close as the Earth's radiation belts and by the United States Environmental Protection Agency.

Figure 2: False-color map of calculations of annual doses (µSv y−1) in North America due to space radiation showing.
The dose from terrestrial sources varies in different parts of the world, but locations with higher soil concentrations of uranium and thorium generally have higher doses.

Plus, in keeping with the elements of a true Network, the GeigerGraph software has its own Chat forum.
