Assessment and Mapping of Ultraviolet Radiation (UV-A) in a Workplace Environment of a Steel Industry

There are different types of furnaces and hot processes in steel industries that may create UV radiation and its adverse effects on the health of the workers. This study aimed at assessing and mapping ultraviolet radiation and comparing it with standards at the Esfarayen industrial complex.
In this cross-sectional study, all parts of the plant complexes were studied. Ultraviolet digital radiometer (model: EC1 Hagner) was used to measure UV radiation. For zoning and drawing a contour map of ultraviolet radiations, the Surfer-v10 software was used.
The results of measurements in different parts of the workshop showed that the highest levels of ultraviolet radiation is in the welding unit (0.32 mw / cm2). Comparison of the values obtained from ultra violet ray measurement with standards showed that all measured values were within the standard range. Contour maps and three-dimensional Wireframe maps of ultraviolet radiation were drawn using the Surfer-v10 software.
According to the obtained results, UV-A radiation in different units of measure in the workshop at all stations are allowed. The results of the measurements are drawn maps to help health and safety officials determine the limits of safety, caution and danger of radiation exposure to reduce exposure by planning for more accurate programs.
