Ultraviolet radiations are reaching alarming levels across the state, including the capital. Jharkhand is already reeling under heat wave conditions, with the average temperature hovering around 43 degrees Celsius. Experts have asked residents to take certain precautions before heading outdoors.
Three global weather agencies – AccuWeather, WeatherOnline and Meteovista – have placed most cities in Jharkhand in the
extreme category – ranging from 10 to 13 of the UV Index.
WeatherOnline’s statistics on Sunday showed the UV index at 12, while AccuWeather’s reading stood at 13. Meteovista, on the other hand, shows the day’s UV index at 10 but it predicted 11+ from Monday till May 27.
A study of the Minimal Erythemal Dose (MED) by the Ranchi-based Birsa Agriculture University (BAU) also suggested that UV radiation has been exceeding the permissible limit in Jharkhand for the last few days. BAU senior meteorological scientist Abdul Wadud said, “We measure MED to understand the level of radiation. The standard unit of MED is one, but it has been observed double between 11 am and 2pm for the past few days. This means that radiation is exceeding the permissible limit.”
Though the India Meteorological Department (IMD), Ranchi has neither authenticated the observations of the weather agencies nor challenged their UV indexes, it has raised some doubts in this regard. "Their studies are not based in standard parameters, but satellite observations. So there is always some doubt on its authenticity," they reported.
