SAVING AN INPUT FILE
You may save an input file at any time by clicking on the Save icon (the floppy disk). The Save
As window will open and you can save the file in the normal Windows manner. Be sure to give
your input file a ".in5" file extension (e.g. filename.in5).
GENERATING AN INPUT FILE WITH RADCAT
When you try to enter a new title for a new file, the Mode Selection dialog box appears. You
must select a transportation mode (highway, rail, or barge) before a new file can be created. A
file cannot be created with more than one mode. Select a mode from the pull-down menu.
The title box says, e.g. "My Truck" (depending on the mode chosen). You may delete this and
type a name for your file in the title box. Your file must have a title. After you type in the title, hit
ENTER, otherwise the title will revert.
The remarks screen is for you to annotate your file; e.g., give a brief description of the problem,
the sources of your input parameters, etc. When you click on Add Remark a line appears in the
remarks screen. The word "REMARK" is on this line. You can delete it and enter your own
remark (up to 80 characters per line. Click on Add Remark to append additional remarks.
CHOOSING YOUR ANALYSIS
Checking the Incident Free box results in analysis of routine, incident-free transportation only.
Checking the Accident box results in analysis of transportation accidents only. Checking both
the Incident Free and Accident boxes results in full analysis of both routine, incident-free
transportation and transportation accidents.
Output may be either as dose or as latent cancer fatalities. Dose output may be in historical units
- rem or person-rem, as appropriate - or Standard International (SI) units - sievert (Sv) or
Some useful conversion factors are:
1 Sv = 100 rem
1 millisievert (mSv) = 100 mrem
1 gray (Gy) = 100 rad
(rem)*(5 x 10-4 ) = latent cancer fatality probability (LCF) for the public
(rem)*(4 x 10-4) = occupational latent cancer fatality probability (LCF)
1 becquerel (Bq) = one disintegration per second, the units of Bq are sec-
1 curie (Ci) = 3.7 x 1010 Bq
Four options are available for controlling output size:
