Estudo conceitual dos sinais-termo da radioquímica em Libras

Abstract

Radiochemistry, a branch of Chemistry focused on the interactions between ionizing radiation and matter, plays a critical role in understanding phenomena such as radioactivity, nuclear decay, and their applications in medicine, energy, and environmental science. Despite its importance, teaching Radiochemistry in Brazil faces significant challenges, particularly regarding accessibility for deaf students. This study aims to conduct a conceptual analysis of the terminological signs used in Radiochemistry in Brazilian Sign Language (Libras), assessing how these signs are produced and interpreted within the deaf community. The research underscores the need for accessible and precise scientific communication, evaluating signs associated with concepts such as atoms, subatomic particles, radiation, and nuclear decay. Morphological and iconic analysis of these signs reveals variations in terms such as atom, proton, neutron, and radiation, which suggest potential conceptual misalignments that could impact scientific understanding. Certain representations, for instance, suggest rotational movement of the atomic nucleus or particles like protons and neutrons, which do not occur according to the Bohr atomic model. Radiation, on the other hand, is frequently linked with danger, potentially fostering a biased and negative perception of Radiochemistry. This study highlights the importance of clear and accurate communication and the need for critical evaluation of terminological signs to ensure both communicability and appropriate conceptual understanding in the technical-scientific field.
