Tabular Data. This Manual supersedes TB CML 92, 14 Feb 63, including all changes. This manual includes Chapter 1. Introduction with a General discussion and a Description. Chapter 2 Operating Instruction includes section I. The ABC-M1A1 RADIAC Calculator and II The M4A1 Nuclear Yield Calculator. With the printed manual is a plastic bag with the designator Calculator Set, RADIAC and Nuclear Yield: BC-M28A1 NSC 6665-00-130-3616. Inside are RADIAC Calculator , ABC-M1A1 which has Instructions on one side and three multicolor circular elements on the other side. The circular calculator has a 4.5 inch diameter. A second disc, entitled Calculator, Nuclear Yield ABC M4A1 is also present with calculation elements on both side. This second circular calculator also has a 4.5 inch diameter. There is a plastic insert with text on each side. One side states Sample Calculations, Calculator, Nuclear Yield, ABC M4A1. The other side states Sample Problem: ABC-M1A1, RADIAC Calculator. The ABC-M1A1 RADIAC Calculator of the M28A1 Nuclear Calculator Set can be used to determine the time of entry into a fallout area when the rate of decay is standard (n = 1.2). To determine the time of entry using the calculator, you must set the known data on the calculator. The dose rate is located on the outer disc and aligned with the H + 1 hour mark on the intermediate disc. Locate the total outside dose on the outer disc and note this position in relation to the guide band on the intermediate disc. Follow this guide band through the intermediate disc and visualize the relative position where the guide band meets the inner disc. Rotate the inner disc until the stay time fits between the relative position on the guide band and the time of entry mark. The time on the inner disc at the time of entry mark represents the time after burst that personnel may enter the fallout area. Note: This calculator is only accurate for "Standard" decay rates. Use the nomograms in U.S. Army Field Manual FM 3-12 Chapter 5 for "Non-Standard" decay rates. Condition: Very good / No Dust Jacket present.
