1. NAME AND TITLE
LINEDOSE: A Line Source Shielding Code for Personal Computers.
Duquesne Light Company, Shippingport, Pennsylvania.
3. CODING LANGUAGE AND COMPUTER
BASIC; IBM PC, TRS-80 Model 4.
4. NATURE OF PROBLEM SOLVED
LINEDOSE computes the gamma-ray dose from a pipe source modeled as a line. The pipe is
assumed to be iron and has a concrete shield of arbitrary thickness. The calculation is made for eight
source energies between 0.1 and 3.5 MeV.
5. METHOD OF SOLUTION
The method of Rockwell is used to find the equivalent line source for the pipe whose parameters
are determined by interactive input. A point kernel integration, using a Berger fit buildup factor, is
6. RESTRICTIONS OR LIMITATIONS
7. TYPICAL RUNNING TIME
LINEDOSE is interactive.
8. COMPUTER HARDWARE REQUIREMENTS
LINEDOSE is operable on the IBM PC and the TRS-80 Model 4.
The IBM PC version requires a printer; the TRS-80 version does not.
9. COMPUTER SOFTWARE REQUIREMENTS
LINEDOSE was implemented in BASIC under PC DOS 2 (IBM PC) and TRSDOS 6.1. Both
versions of BASIC are dialects of MS BASIC.

11. CONTENTS OF CODE PACKAGE
Included are the referenced document and one (1.2MB) DOS diskette on which the program
versions are written as ASCII files.
