INFANTES VIZCARRA, Walter Iván. Genetic biomonitoring in workers of the radiology service of a National Hospital Luis N. Saénz. Rev. Fac. Med. Hum. [online]. 2020, vol.20, n.1, pp.51-54. ISSN 1814-5469.


To evaluate the genotoxic effect on workers exposed to X-rays in the radiology service of the Luis N. Sáenz national hospital PNP.


The type of study was observational, prospective, analytical, using the comet assay as an analysis technique. The study population was 20 workers exposed to X-rays and 20 people without exposure.


The mean length of migration of damaged DNA in the control group was 1,28 ± 0,38 µm compared to 10,39 ± 9,44 µm for the exposed group (p=0,001). DNA damage was significantly correlated with years of exposure and dose received (p <0,05) but not with age.


X-rays at low permissible doses can cause damage to DNA integrity, correlating with the years of exposure and total dose exposure of personnel working in the radiology service.
