RAMOS-AVASOLA, Sergio et al. Citogenetic effects upon lymphocyes in subjects exposed to ionizing radiadion in an interventional laboratory cardiology: Pilot study and literature review. Rev Chil Cardiol [online]. 2020, vol.39, n.1, pp.8-15.  Epub 01-Abr-2020. ISSN 0718-8560.


There is growing evidence of an increased number of chromosomes aberrations in subjects exposed to low levels of ionizing radiation (POEs). There are few studies on this subject in Latin America


To evaluate the frequency of chromosome aberrations in lymphocytes obtained from peripheral blood in subjects working in laboratories where low levels of ionizing radiation are present and to compare these findings to those of unexposed subjects.


A cytogenic analysis to quantify chromosome aberrations was performed in 6 POs subjects from a cardiology invasive laboratory and 6 controls from a general unexposed population.


Compared to controls, an approximately 6-fold increase in the number of chromosome aberrations was subjects exposed to ionizing radiation


These preliminary results indicate that there is an increased number of chromosome aberrations in subjects exposed to low levels of ionizing radiation, as occurs in people working in a cardiology interventional laboratory. Studies in large numbers of subjects and preferably followed prospectively are needed to evaluate more precisely this effect.

Palabras clave : Chromosome aberrations; ionizing radiation; occupational hazard.
