Abstract
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. http://dx.doi.org/10.25176/rfmh.v20i1.2256.
Objective:
To evaluate the genotoxic effect on workers exposed to X-rays in the radiology service of the Luis N. Sáenz national hospital PNP.
Methods:
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.
Results:
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.
Conclusions:
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.
