Abstract
  • The environmental impact of the nuclear industry has prompted the need for innovative remediation strategies and accurate radiological assessments. This paper synthesizes three studies that collectively explore the potential of endemic plant species for phytoremediation, the development of anatomically accurate phantoms for precise dosimetry calculations, and the critical evaluation of International Commission on Radiological Protection (ICRP) guidelines using in situ plant analyses. The first study investigates phytoremediation at legacy uranium mining sites in the Colorado Plateau, focusing on endemic plant species such as Sporobolus airoides, Helianthus petiolaris, Kochia scoparia, and Atriplex canescens. The second study scrutinizes the environmental radiological protection guidelines proposed in ICRP Publications 108 and 136 through the lens of in situ plant analyses, revealing the potential for refining the Reference Animals and Plants (RAPs) approach and dose coefficients. Lastly, the third study introduces FSOPhantom, an open-source software designed for generating anatomically accurate phantoms from CT and MRI images, producing a novel dosimetric model for the common banana (Musa acuminata Colla) as an example. By integrating innovative remediation strategies, anatomically accurate dosimetry models, and real-world data, this research aims to enhance the assessment and management of radiological contamination, ultimately contributing to more effective environmental protection and public health outcomes.
