Radiological Benefit-Risk Index for Food (IRBRF)
Radiological Benefit-Risk Index for Food (IRBRF)
This page hosts the software for the Radiological Benefit-Risk Index for Food (IRBRF) calculator.
The IRBRF was developed to address a gap in food safety assessment. While international bodies like the ICRP provide robust tools for calculating the radiological dose from ingesting radionuclides, there has been no unified framework to weigh that radiological risk against the nutritional benefits of food. The IRBRF was created to be a simple, quantitative tool that bridges this gap, providing an integrated measure that balances a food's nutritional profile with its radiological risk.
You can download the calculator by clicking the link below. The primary scientific article detailing the IRBRF framework can also be accessed through the adjacent link. This paper presents a comprehensive radiological evaluation of 13 flours from Brazilian sociobiodiversity, establishes the first radiometric characterization for many of these products, and details the development and application of the IRBRF index to differentiate their safety profiles.

Note: It is possible that upon running the program, Windows Defender will display a security warning. This can happen because the program was built using Tkinter for its graphical interface. If this occurs, please click "More info" and then "Run anyway" to proceed.
