Eckerman's DFINT, DFEXT, and CHAINS Codes

These MS-DOS codes look up the dose coefficients from Federal Guidance Reports 12 and 13 and assemble the decay chains as defined in ICRP-38. They are contained in the downloadable file DFACT.EXE. You will need at least 2 MB of disk space for downloading and unpacking these codes.
