The first volume in this series, Total Fallout–General Reader Edition, includes several tables that lists fallout deposition values on a county-by-county basis. Unfortunately, due to page limitations, it was not possible to include the lowest values–i.e. those in the single-digit micro-Curie range. This edition of the series addresses this limitation by segregating the fallout values into two groups–counties in the Eastern half of the United States and counties in the Western half of the United States. The states included in Volume III (Eastern U.S.) include: Alabama, Arkansas, Connecticutt, District of Columbia, Delaware, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana, Massachusetts, Maryland, Maine, Michigan, Mississippi, North Carolina, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Virginia, Vermont, Wisconsin and the District of Columbia. The states included in Volume IV (Western U.S.) include Arizona, California, Colorado, Idaho, Iowa, Kansas, Minnesota, Missouri, Montana, North Dakota, Nebraska, Nevada, Oklahoma, Oregon, South Dakota, Texas, Utah and Washington.
