Description/Abstract:
A couple of years ago Higgins and Keller, described a calculational method to assess the possible problems arising from cratering shot radioactive materials finding their way into the human body and producing an internal radiation dose. Since then Yook Ng has modified, extended and expanded the mathematical technique. Ng considers two entry path ways into the body; one via foliage deposition and, thence, by cows milk, and the other via soil deposition and the plant root pathway. In the general case, a dose from a particular radioactive nuclide is calculated in terms of the curies of that nuclide deposited per unit area. Thus, the internal dose and distance relationship calculated for a specific cratering event depends, in part, upon the fallout prediction method used. Ng5 has made internal dose and distance calculations for CABRIOLET and then applied these results to a 300-device detonation scheduled for an American Isthmian Canal. It is the purpose of this memorandum to provide some comments concerning the canal calculation distances for particular doses found in Ng's UCRL-14956.
