radioactive

☢️ The radioactive symbol, also known as the trefoil, is an internationally recognized warning sign for ionizing radiation or radioactive materials. It was created in 1946 at the University of California, Berkeley's Radiation Laboratory to alert people to hazardous areas. This symbol is commonly found in nuclear facilities, radioactive waste sites, medical radiation equipment, and on packaging containing radioactive substances. In internet culture, it is sometimes used metaphorically to indicate something 'toxic,' 'dangerous,' or 'extreme,' carrying a strong warning and negative emotional connotation.
