A burning hydrogen flame, for instance, radiates strongly in the 185- to 260-nanometer range and only very weakly in the IR region, whereas a coal fire emits very weakly in the UV band yet very strongly at IR wavelengths; thus, a fire detector that operates using both UV and IR detectors is more reliable than one with a UV detector alone.
Flash burn is any burn injury caused by intense flashes of light, high voltage electric current, [1] or strong thermal radiation. [2] These may originate from, for example, a sufficiently large BLEVE, a thermobaric weapon explosion or a nuclear blast of sufficient magnitude. Damage to the eye(s) caused by ultraviolet rays is known as ...
The ultraviolet index, or UV index, is an international standard measurement of the strength of the sunburn-producing ultraviolet (UV) radiation at a particular place and time. It is primarily used in daily and hourly forecasts aimed at the general public.
The Kenneth Fire expanded to 1052 acres in a matter of hours but is now 100 percent contained. The wind whips embers while firefighters battle the fire in the Angeles National Forest near Mt ...
According to the Fire and Smoke Map from AirNow.gov, which monitors air quality across the United States, wildfires are currently burning across the country.

People living in the Midwest and Northeast were warned of a worsening air quality index throughout the week due to smoke from the Canadian wildfires
The most common type of radiation burn is a sunburn caused by UV radiation. High exposure to X-rays during diagnostic medical imaging or radiotherapy can also result in radiation burns. As the ionizing radiation interacts with cells within the body—damaging them—the body responds to this damage, typically resulting in erythema —that is ...
