This PowerPoint presentation will discuss planned updates to the online model known as the Preliminary Remediation Goals for radionuclides (PRG) electronic calculator to improve tribal risk assessments. The PRG calculator is used in risk assessments and developing risk based cleanup levels for radioactively contaminated soil and water. The PRG calculator risk estimates can include the consumption of radioactively contaminated biota (25 types of produce and 14 farm animals) by humans. To improve consideration of tribal-specific exposure pathways, EPA has collected information on additional animal and produce products that are more commonly consumed by tribes and is evaluating 30 animal products and 70 produce to add to the PRG calculator in 2024.
