Cross-dose S values have been calculated for eight different combinations of diameters of the cell (RC) and cell nucleus (RN). As denoted in Table 1, eight folders of files have been created, one for each combination of cell sizes. Within each folder are cross-dose S values for 70 different radionuclides. If photons are emitted by the radionuclide, the beginning lines indicate the photons that were ignored in the calculations. The first line that follows this information describes the file that the radiation data was taken from. This is followed by the number of lines of S value data in the file. Five columns of S value data then follow. Columns 1, 2, 3, 4, and 5 are the S values for the following target source configurations: C←C, C←CS, N←N, N←Cy, and N←CS, respectively. The first row is the self-dose to the target cell. The rows with zeros should be ignored. The first row after the zeros is the S value for when the target and source cells are touching so that the distance d between their centers is one cell diameter. The next row of the S values is for when the centers of the target and source cells are spaced by one cell diameter + 1 µm. In the S value rows that follow, the distance between the centers of the cells is incremented by 1 µm. In the rows that follow the S Value data are details regarding the input parameters, including the actual radiation data used in the calculations. The example in Table 2 for 125I shows the S value data for 125I that is taken from file i125.53.
