The desired audience for this presentation would be Tribal Environmental Professionals. I plan on discussing the Navajo Abandoned Uranium Mines Risk Calculator. The discussion will focus on the development of Navajo-specific human health preliminary removal goals (PRG) to be considered during removal action goal (RAG) development at NAUM sites. The presentation will inform the audience on how tribal and federal partners to work on creating tribal specific input parameters that take tribal lifeways into consideration.
