1. NAME AND TITLE
KRONIC: Calculation of Annual Average External (Beta and Gamma Radiation) Doses from Chronic Atmospheric Releases of Radionuclides.
Battelle Pacific Northwest Laboratories, Richland, Washington.
Ralph M. Parsons Company, Pasadena, California.
3. CODING LANGUAGE AND COMPUTER
FORTRAN IV; UNIVAC 1108 (A) and CDC CYBER-74 (B).
4. NATURE OF PROBLEM SOLVED
KRONIC calculates the annual average beta- and gamma-ray doses resulting from chronic release of radionuclides to the atmosphere. The dose calculations are performed for each sector about the release point and use frequency of occurrence data for atmospheric stability and wind speed.
5. METHOD OF SOLUTION
The infinite medium model is used for beta rays and kernel integration for gamma rays.
6. RESTRICTIONS OR LIMITATIONS
7. TYPICAL RUNNING TIME
No study has been made by RSIC of typical running times for KRONIC.
8. COMPUTER HARDWARE REQUIREMENTS
KRONIC is operable on the UNIVAC 1108 (A) or the CDC CYBER-74 (B) computers.
9. COMPUTER SOFTWARE REQUIREMENTS
A FORTRAN IV compiler is required.
