CCC-0556 QUINCE

1. NAME OR DESIGNATION OF PROGRAM:  QUINCE

3. DESCRIPTION OF PROGRAM OR FUNCTION

The program QUINCE is an
enhanced version of the VARSKIN code (CCC-0522) which computes absorbed dose and survival from a disc or point source on the skin surface, irradiating cells at the base of the skin.

4. METHOD OF SOLUTION

VARSKIN assumes that the dose from the last point of integration was close to zero and any remaining dose from that point was negligible. QUINCE was modified to add the dose from  the last integration point out to the maximum range based on a straight line extrapolation to zero. QUINCE provides a smooth integral function by which the integrated dose is obtained, as opposed to the step function method in VARSKIN. QUINCE allows dose calculation for mixtures of up to five isotopes whereas VARSKIN requires separate runs for each isotope in the mixture. QUINCE prints dose averaged over a one square centimetre area and the new area that is selected.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM:  QUINCE allows mixtures of up to five isotopes.

6. TYPICAL RUNNING TIME

The code is interactive. The sample input took only a few seconds on an IBM PC/XT (4.7 megahertz) running under DOS 3.3 with a math coprocessor.

11. MACHINE REQUIREMENTS

IBM PC and compatibles. A math coprocessor is not required.

The sample problems were run at the NEA-DB on a PC DELL 466/L with 80486 processor, 66 MHz, and 16 MBytes of RAM. The size of the executable file produced using the Microsoft compiler and linker is 75 Kbytes, whereas the size of the QUINCE executable file created using the Lahey compiler and linker (using the stub loader) is 321 KBytes.

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED

The code was written in FORTRAN 77 and tested under PC-DOS (IBM PC). An executable file produced by the MICROSOFT FORTRAN Version 4.01 is included.

QUINCE was run at the NEA-DB under MS-DOS 6.2. Two different executable files were created, compiled and linked, respectively with: - the Lahey F77L-EM32 FORTRAN 77 compiler version 5.20 and the Lahey linker 386LINK version 5.1; and - the Microsoft FORTRAN-77 compiler version 5.10 and linker version 5.15.
