Measurement and Prediction of Workplace Exposure to Solar Ultraviolet Radiation in Makurdi, Benue St

Aims: To measure and anticipate the workplace uncovering to solar ultraviolet dissemination in Makurdi, Benue State, Nigeria.Study Design: Experimental design through area listening method and Newton detached interpolation distinctness method.Place and Duration of Study: Makurdi Metropolis, Benue State and Department of Physics, Nasarawa State University Keffi, Nigeria, betwixt April and June 2021.Methodology: Digital broad band meter was used to measure UV irradiance at SRS connection (Traffic light) and Kanshio (construction section) at hourly breaks from 10:00am- 4:00pm. The exposure results were used to evolve a predicting function utilizing the Newton Divided Difference Interpolation method and were schemed into MATLAB to generate the envisioned results. Also, the UV index was also premeditated.Results: The mean irradiant principles were 179.100J/m2 and 173.53J/m2 with erythema persuasive irradiances 227.300J/m2 and 205.000J/m2 which is 1.14 and 1.03 minimum erythema doses (MED)/hr, while the thought mean values were 179.100±0.025J/m2 and 172.800±0.004J/m2 for the traffic wardens and creation site peasants respectively. The mean principles were higher than the ICNIRP urged safety limit of 30.000J/m2 for pertaining to work exposure and MED for skin type I was surpassed by a factor of 1. The planned UV index was 8 for construction spot and 9 for traffic light wardens.Conclusion: High level of veracity of the prediction model means that it can be secondhand for prediction of SUV dissemination. However, high mean bright values accompanying high UV index displays high risk of harm from defenseless sun uncovering. Therefore, use of sun guarding clothing is urged and reduce be present at the sun exceptionally between 1:00pm and 2:00pm for fear that over exposure that will bring about serious injurious effects.
