ANÁLISE DE ÍNDICES HEMATOLÓGICOS DE PROFISSIONAIS EXPOSTOS À RADIAÇÃO IONIZANTE

Abstract

Hematological study carried out in Varginha/MG, from samples collected during three consecutive months in 2008, from 25 professionals who operate X-ray emitting devices. The professionals involved include radiotherapy and radiodiagnostic technicians, and dentists who perform dental radiography. As radiation is known for its deleterious effects on the body, and these professionals are daily subject to receiving a dose, even if minimal, in their work environment, the objective of this research was to verify whether occupational exposure to radiation can cause changes in rates of the professionals involved, during their workday. The blood, collected in the workplace of the researched and analyzed in an automated way in the laboratory that supported the research, later analyzed manually by reading the blood smears, showed some changes in several elements of the hemograms performed, mainly on the red series where they were anemias were found, but none of these alterations had relevant clinical significance. A pre-analytical questionnaire was previously applied to the professionals, so that the changes found could be related to some factors that could be the reason for their occurrence, or to prove the influence of radiation on the hematological tissue of the respondents. elements of the questionnaire with the changes found, there was also the opposite, in which the comparison showed that there was not enough interaction for the occurrence of such changes. Due to the disagreement of the results and the values ​​obtained being insufficiently significant, the main cause was not attributed to the effect of ionizing radiation on the researched blood.
