1. NAME AND TITLE
PROCIV: A Code System for Calculating the Protection Factors Against Radioactive Fallout for
Joint Army-Civil Defense Committee, Arcueil, France, through the OECD Nuclear Energy
Agency Data Bank, Gif-sur-Yvette, France.
3. CODING LANGUAGE AND COMPUTER
Fortran V; UNIVAC 1110.
4. NATURE OF PROBLEM SOLVED
PROCIV calculates the protection factors against radioactive fallout for apartment buildings. There
are three versions of the code: (1) calculations made on an isolated dwelling, (2) calculations made on
a dwelling accounting for the surroundings, (3) like version 2 but imposing 12 environmental
possibilities that are common in a residential area.
5. METHOD OF SOLUTION
Each house is simulated by a cylindrical tower. The material thickness traversed by the photons
is converted to an equivalent layer of air. The masking by neighboring houses is taken into account.
6. RESTRICTIONS OR LIMITATIONS
7. TYPICAL RUNNING TIME
No study has been made by RSIC of typical running times for PROCIV.
8. COMPUTER HARDWARE REQUIREMENTS
PROCIV operates on the UNIVAC 1110 computer.
9. COMPUTER SOFTWARE REQUIREMENTS
A Fortran V compiler is required.
