GENERAL INFORMATION ABOUT RADDECAY
(Version 2.01 - Text compiled with program)
1. INTRODUCTION
RADDECAY is a program for displaying radioactive decay information for 497
radionuclides. Data provided include the half life, radioactive daughter
nuclides, probabilities per decay, and decay product energies for alphas,
betas, positrons, electrons, X-rays, and photons.
2. INSTRUCTIONS FOR THE FIRST-TIME USER
All information regarding RADDECAY is on the system diskette. To get started,
use any drive and type "RADDECAY". This will execute the program and make
information available via menu selections. The files may be copied to and
executed from a hard disk. There is no copy protection.
The second diskette contains seven "record" (random access) files which
contain all the data. They have an extension of ".REC" with file names that
are self explanatory. These files do not have to be on the same drive or DOS
directory as the system diskette files. However, they must all be in one
directory or sub-directory. More information regarding these files can be
read by selecting the file information menu item.
When RADDECAY executes, it initially reads a file in the same directory with
the name RADDECAY.DAT. This file contains parameters which control the screen
colors and the DOS path to the data contained in the *.REC files. If this
file is not found, then one is created with:
a) Default screen colors. If you cannot see the screen because of
a strange color combination, press [Esc] from the menu to re-set them.
b) The path to the *.REC files as the current directory from which
RADDECAY was executed.
When you set these parameters from RADDECAY main menu, they are retained in
the RADDECAY.DAT file for the next time the program is run. As received,
there is no file on diskette, so it will be created with the defaults the
first time it is used.
If you have a hard disk or an IBM-PC AT with a high capacity drive, we
recommend that you create a subdirectory (for example, C:\RADDECAY\) on the
high capacity drive and copy files RADDECAY.EXE, and all seven .REC files
to it. Then, when you first run RADDECAY, set the path and colors by
pressing [Esc]. If you use the nuclide record files for other programs such
as Grove Engineering's Microshield or MicroSkyshine, then you should set the
record files path to the same subdirectory as for these programs. This will
avoid replicate copies of the same data on your hard disk.
3. PERMISSION FOR MAKING COPIES
The two diskettes provided are "plain vanilla". Permission is granted for
making copies of RADDECAY without any restrictions.
4. PERMISSION FOR USE OF THE SOURCE CODE
Source code provided is sufficient for checking the algorithms use in RAD-
DECAY. Programmers may use the source code to any extent they desire. We
heartily encourage microcomputers for engineering and analysis work. Note
that you will not be able to compile RADDECAY without licensed True Basic
library and Grove Engineering library routines for machine interaction. When
you create a program that uses any of the .REC files, you should acknowledge:
a) RSIC (see 5. below) as the original source of the data, and
b) Grove Engineering as the originators of the microcomputer formatted
files.
5. SOURCE OF DATA AND DECAY ALGORITHM
Thanks are due to the Radiation Shielding Information Center (RSIC) at Oak
Ridge National Laboratories which provided the nuclides library information
on diskette so that we could adapt it; and to Dick Bowers of the Perry Nuclear
plant who provided the decay algorithm.
The data contained in these files from the RSIC were received in mid-1986 and
is presumed current to that time. These data are the same as that in:
RADIOACTIVE DECAY DATA TABLES
by David C. Kocher
Report DOE/TIC-11026
Technical Information Center
U.S. Department of Energy,
Washington, D.C., 1981
which is available through NTIS. We are grateful to RSIC, a government
sponsored organization, for providing this public-domain information.
Grove Engineering added C-15 to this library for purposes of N-16 radiation
shielding calculations. Altogether, there are 497 nuclides.
6. CONVERSION TO MICROCOMPUTER FORMAT
The data were converted to random access record files by:
Grove Engineering

Rockville, MD 20850
Phone (301) 258-2727
Dave Tocus is the programmer who did much of the neat stuff that makes this
program extremely easy to use. We used the True Basic programming system
which proved to be outstanding. The team of creators of RADDECAY are very
pleased with the result. We trust that you will find this program useful.
Grove Engineering provides energy and electricity-related engineering and
management consulting services to utility, industrial, and maritime
organizations; and to the U.S.Navy.
