The manuscript's purpose is to increase the current knowledge of uranium levels in a sea shore environment near phosphate deposits in Baja California Sur for future identification of natural enrichment in coastal habitats. A study research plan was designed and presented in this thesis. It includes: (1) a uranium overview (radiation principles, uranium chemical- and radio-toxicity, and environmental distribution); (2) a preliminary study results, discussion, and conclusions; (3) a research proposal to quantify the environmental levels in La Paz Bay, Mexico; (4) suggestions of other potential methods to evaluate the association between the uranium leached from the phosphate deposits and cancer risk.;The proposal's approval and subsequent completion would reveal the most important pathways (air, marine and terrestrial sediments, natural waters) of accumulation with relevance for human populations. |
