Verification of the RESRAD-BUILD Computer Code
S. Kamboj, C. Yu
RESRAD-BUILD is a pathway analysis model designed to evaluate the potential radiological dose to an individual who works or lives in a building contaminated with radioactive material. The transport of radioactive material inside the building from one compartment (or room) to another is calculated with an indoor air quality model. This paper discusses verification of the models which was performed by using Microsoft Excel® spreadsheets and hand calculations. RESRAD-BUILD calculations verified included the source injection rate, air concentration in a compartment, air particulate deposition, exposure pathway doses, and time dependence in dose calculations. The direct external exposure pathway doses were also compared with Monte Carlo N-particle (MCNP) calculations. The agreement between the code output and spreadsheet calculations was excellent for all pathways. The paper also discusses limitations of the verification process and provides suggestions for future improvement of the RESRAD-BUILD code.
