Appendix E
Nomograms and Tables
This appendix contains nomograms and tables for use in radiological calculations, a hairline for local reproduction, and a map scale for use in total dose calculations (crossing problems).
Tables beginning Table E1 are set to tabular format. They are presented with their corresponding nomograms. To determine the radioactive cloud and stem parameters, find the appropriate yield in the lefthand column (Table E1) and read the data across the table.
Stabilized cloudtop and cloudbottom angle yield estimation is presented in Table E2. Enter the table with the stabilized cloudtop or bottom angle in the lefthand column. Read across the top of the table with the flashtobang time or distance to ground zero. Where the two columns intersect is the estimated yield, some mathematical estimation may be required.
To determine the downwind distance of Zone I (zone of immediate concern) (Table E4), find the appropriate yield in the lefthand column, and the effective wind speed across the top. Where the two columns intersect is the downwind distance of Zone I.
For fallout decay (Table E5), enter with the R_{1} value on the left side, and t in hours across the top. Where the two columns intersect is the Rt value. To determine the R_{1} value, find the Rt value in the t column and read across to the left to determine R_{1}. Some mathematical estimation of the data may be required.
To determine total dose (Table E24), enter the table for the appropriate decay rate with the Te value in the lefthand column and the Ts value across the top. Where the two columns intersect is the value for the index scale. Turn to Table E43 for the index table. Enter the index value across the top of the table and the R_{1} value down the left hand side. Where the two columns intersect is the total dose. If the index and R_{1} values are not present in the table either multiply the index value by R_{1} value for a product in total dose, or mathematically estimate the data in the table.
