A recent study published in the journal ‘Bibechana’ has shed light on the ultraviolet (UV) index across various locations in Nepal, revealing significant insights into the potential health risks associated with UV radiation exposure. Conducted by Isman Mainali from the Central Department of Physics at Tribhuvan University, the research analyzed UV index data from 2001 to 2021, focusing on six distinct sites at varying altitudes and latitudes.
The findings indicate that the UV index during solar noon is particularly high in Dolpa, where it reached an average value of 9.10, categorizing it as very high according to World Health Organization (WHO) guidelines. Other locations, including Birgunj, Hetauda, Rolpa, and Tulsipur, also exhibited elevated UV index values, ranging from 5.45 to 8.43. The study highlights that during the mid-summer months of June through August, all these areas fall within the high or very high UV index categories, posing a risk to the local population.
Mainali emphasizes the importance of this research in understanding environmental changes and public health risks. “The spectral measure of solar UV radiation helps us to understand the causes of change in the environment and also raise public awareness about potential threats,” he states. This awareness is crucial, especially for communities in high UV index areas, who may need to adopt protective measures against harmful radiation.
The implications of this study extend beyond public health. For the energy sector, particularly in solar energy development, understanding UV radiation levels can inform the design and placement of solar panels. Locations with high UV exposure may enhance the efficiency of solar energy systems, presenting commercial opportunities for solar energy companies looking to optimize energy production.
As the demand for renewable energy sources continues to grow, insights from this research could guide investments in solar infrastructure in regions identified as having high UV indexes. Additionally, the study underscores the need for educational campaigns about UV exposure and the importance of protective measures, which could foster partnerships between public health organizations and energy companies.
In summary, the research conducted by Isman Mainali and published in ‘Bibechana’ not only raises awareness about the risks associated with UV radiation but also opens up avenues for commercial opportunities in the energy sector.
