Sunburn effect (as measured by the UV index) is the product of the sunlight power spectrum (radiation intensity) and the erythemal action spectrum (skin sensitivity) across the range of UV wavelengths. [9] [10] The UV index is a number linearly related to the intensity of sunburn-producing UV radiation at a given point on the Earth's surface.
According to the National Toxicology Program Report on Carcinogens from the US Department of Health and Human Services, broad-spectrum UV radiation is a carcinogen whose DNA damage is thought to contribute to most of the estimated 1.5 million skin cancers and the 8,000 deaths due to metastatic melanoma that occur annually in the United States.
Highest ultraviolet index measured: On 29 December 2003, a UV index of 43.3 was detected at Chile/Bolivia's Licancabur volcano, at 19,423 feet (5,920 m) altitude. A light-skinned individual in such conditions may experience moderate sunburn in as little as 4 minutes.
Sunburn is a form of radiation burn that affects living tissue, such as skin, that results from an overexposure to ultraviolet (UV) radiation, usually from the Sun.Common symptoms in humans and other animals include red or reddish skin that is hot to the touch or painful, general fatigue, and mild dizziness.
However, in late January 2019, a violent polar vortex drifted southward, enveloping the city in new record-breaking temperatures as low as −23 °F (−31 °C) on January 30, though the city just missed out on tying the all-time record low maximum temperature, recording a high of −10 °F (−23 °C) one day during the outbreak.
Between 2022 and 2023, nonalcoholic beverage sales increased by 32%, while total alcoholic beverage sales for the same period only increased by 1%, according to a Pennsylvania State University report.
An MED is the amount of UV radiation that will produce erythema (redness of the skin) within a few hours of exposure. [26] High-pressure beds use smaller, higher-wattage quartz bulbs and emit a higher percentage of UVA. [27] They may emit 10–15 times more UVA than the midday sun, [20] and have a shorter maximum exposure time (typically 10 ...
