1. NAME AND TITLE
INGDOS: A Conversational Code System Designed to Implement NRC Reg-Guide 1.109 Models
for Estimation of Annual Doses from Ingestion of Atmospherically Released
Radionuclides in Foods.
Oak Ridge National Laboratory, Oak Ridge, Tennessee.
3. CODING LANGUAGE AND COMPUTER
Fortran IV; PDP-10.
4. NATURE OF PROBLEM SOLVED.
INGDOS computes doses to various organs of man resulting from the ingestion of food
contaminated by atmospherically released radionuclides.
5. METHOD OF SOLUTION
INGDOS is designed for implementation on a PDP-10 system for use in time-sharing mode. An
on-line data base provides default values for most of the parameters required in the calculations. For
all nuclides included in its data base, INGDOS computes annual doses and prints, at the user's option,
doses via various pathways as well as total doses and ratios of total doses to ground-level air
6. RESTRICTIONS OR LIMITATIONS
7. TYPICAL RUNNING TIME
The sample problem, when run in batch mode, requires only 0.15 CPU minutes.
8. COMPUTER HARDWARE REQUIREMENTS
The sample problem required 130 K on a PDP-10 computer.
9. COMPUTER SOFTWARE REQUIREMENTS
A Fortran IV compiler is required.

11. CONTENTS OF CODE PACKAGE
Included are the referenced document and one (1.2MB) DOS diskette which contains the source
code, sample problem input, and data libraries.
