3. DESCRIPTION OF PROGRAM OR FUNCTION

The Clean Air Act Assessment Package-1988 (CAP-88) is designed for assessment of dose and risk from radionuclide emissions to air in compliance with National Emission Standards for Hazardous Air Pollutants (NESHAPs) for Radionuclides. CAP-88 estimates health impacts from the inhalation,  ingestion, air immersion and ground surface irradiation pathways, and tabulates results for maximally exposed individuals and regional populations out to 80 kilometers. The system provides risk information in a concise, easy-to-read format and prints an echo of  the input.
CAP-88 consists of updated versions of the mainframe codes AIRDOS-EPA and DARTAB. Atmospheric dispersion and deposition are calculated by AIRDOS2. Dose and risk assessment tables are calculated by DARTAB2 from the binary output file produced by AIRDOS2 and a file of dose and risk factors calculated by RADRISK. Preprocessors (PREPAR2 and PREDA) for AIRDOS2 and DARTAB2 access data bases of element and nuclide dependent data to simplify the execution of the principal programs.

4. METHOD OF SOLUTION

AIRDOS-EPA implements a long term average Gaussian Plume model. The associated terrestrial model for deposition is based on NRC Regulatory Guide 1.109. The 50-year effective dose equivalent factors for DARTAB2 are calculated by RADRISK and use weighting factors from ICRP-26. Risks are calculated using a linear Life Table model consistent with BEIR-3. The resultant risk factors are 4.0E-4 cancer deaths per rem and 3.6E-4 cancer deaths per person working-level-month exposure to radon decay products.
CAP88-PC (CCC-0542/02) is able to use population data and weather data downloaded from mainframe versions of CAP-88. CAP88-PC also comes with sample population arrays from some DOE facilities, and includes weather data from many DOE sites and major U.S. cities.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Programs are limited to 36 radionuclides and to 20 downwind distances for each of 16 compass directions. CAP88-PC is intended for use by health physicists experienced in dose assessment. CAP88-PC is based on the  Gaussian plume model with its associated limitations. The model is intended only for evaluating low-level, chronic releases; it is not  appropriate for short-term accidental releases.

6. TYPICAL RUNNING TIME

A complete run, including PREPAR2, AIRDOS2, PREDA, and DARTAB2, for an individual and population assessment requires approximately one and two minutes of CPU time, respectively, on an IBM 3090 processor. The same problem on a PC/80286 (12 MHz) took about 25 minutes.
CCC-0542/02
The assessment for the default dataset "REACTIVE METALS" was performed at the NEA-DB in about 20 seconds (elapsed time) on a 66-MHz PC/80486.

11. MACHINE REQUIREMENTS

CAP-88 is operable on the IBM mainframe computers. Memory regions for execution on an IBM 3090 system under  MVS are as follows: PREPAR2, 1200K; AIRDOS2, 900K; PREDA, 300K; and  DARTAB2, 800K. Version B was tested on a VAX 6000. CAP88-PC requires a MS-DOS compatible personal computer with a hard  disk with at least 3.5 MB of free space, 500K free RAM and a math co-processor.
CCC-0542/02
The default dataset was run at the NEA-DB on a PC DELL  466/L (80486 processor, 66 MHz, 16 Mbytes RAM). The file sizes of the executable versions are 66 Kbytes (CAP88PC.EXE); 60 Kbytes (DEFAULT.EXE), 370 Kbytes (DARTAB.EXE); 408 Kbytes (AIRDOS.EXE); 83 Kbytes (INTRO.EXE).

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED

The IBM system compiled under OS/VS2 using the IBM VS compiler. The VAX version was tested using the VMS 5.4 FORTRAN compiler.
To run CAP88-PC, Turbo C++ Version 1.0 and Lahey F77L Version 4.10 were used to create the executables.
CCC-0542/02
The program was run under MS-DOS 6.0. The FORTRAN77 Lahey compiler F77L-EM/72 version 5.11 and the linker 386LINK were used to recreate the executable versions DEFAULT.EXE, DARTAB.EXE and AIRDOS.EXE.
