    A Drone-Based Approach for Radiometric Mapping of Gamma Radiation by Felipe Mamed, Alessandra Vaz, Ary Machado, Joana Batista, Jonathan Oliveira, Paulo Silveira, Paulo Iack, Paulo Barreto, William Henrique, Wallace Vallory

    Published 2025-03-01

Since specific patterns in the graphs, such as a sudden increase in dose rate in a particular direction, can indicate the presence of a source, we consider that this method can be employed as a useful strategy for the remote detection of radiation sources in various environments, offering a satisfactory approximation of the radiological conditions present in the analyzed environment. …”
