3. DESCRIPTION OF PROGRAM OR FUNCTION

PUTZ calculates dose rates from three-dimensional photon sources in a three-dimensional system. The  code allows the specification of the source and body geometries as simple parallelepipeds and annular parallelepipeds (tanks) and permits the inclusion of multiple sources and multiple detectors in  a single case. The shielding bodies may consist of up to 6 materials.

4. METHOD OF SOLUTION

The point-kernel method employs the Geometric-Progression (GP) formula for the buildup factor. The GP coefficients and attenuation coefficients, taken from the ANSI/ANS-6.4.3-1991 compilation, are read from a data file. An optional multimaterial (composite) buildup factor formula may be used. The FIDO input system is used which allows easy entering or modifying the various input arrays.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Photon source energies are limited to values between 15 keV and 15 MeV. A total of 6 shielding materials can be treated. All bodies are solid parallelepipeds or parallelepiped shells (tanks.)

6. TYPICAL RUNNING TIME

The 2 sample problems took 4.95 and 18.84 seconds on a 25 MHz PC 386.

11. MACHINE REQUIREMENTS

The code was tested on a PC 386, but should run on all IBM PC compatible computers having a math coprocessor.
CCC-0595/02
The program was compiled and the test cases executed by NEA-DB on a DELL 486P/33MHz compatible PC.

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED

The code was written in Fortran 77 and was tested using the Microsft version 5.0  compiler. For implementation on other systems, the OPEN statements are placed in one subroutine (SETIO).
CCC-0595/02
The program was compiled using the Lahey F77L3-EM32 Version 4.02 Fortran-77 compiler and linked with the Lahey LINK-EM/32 Version 2.06 linker in connection with the Lahey/Ergo OS/386 DOS Extender Version 4.02. The PC ran under MS-DOS 5.0.
