1. NAME AND TITLE

LINEDOSE: A Line Source Shielding Code for Personal Computers.

2. CONTRIBUTOR

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 employed.

6. RESTRICTIONS OR LIMITATIONS

None noted.

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.

12. DATE OF ABSTRACT
