Something doesn't work?

  • The Num lock should always be enabled. If it is disabled when you are attempting an alt code, it may cause errors or unexpected results in some applications. For example, Alt+4 could be interpreted as Alt +, ← which causes the browser to go back if the Num lock is disabled.
  • If your laptop keyboard doesn't have a separate NumPad, you should hold FN button with Alt button while typing the code.
  • This method does not work for Linux system, but it is possible to use Unicode.

Nuclear Symbol

Nuclear symbol meaning

Nuclear symbol, also known as warning symbols or hazard symbols, are recognizable symbols created to warn people about dangerous or hazardous locations, materials, objects, like poisons, electric currents, and radioactivity. The use of nuclear symbols is often controlled by law and administered by standard organizations. Nuclear characters are designed in different colors, borders, backgrounds, and supplemental information to specify the danger and threat level (for instance, toxicity classes). Nuclear symbols are used in various places of or beside to written warnings since they are eye-catchy and quickly recognized, even faster than reading a written warning.

The nuclear symbol is quite similar to the Radioactive sign, which is the international biohazard symbol used as a warning sign against biological substances that cause a threat to the health of living organisms of humans. Besides, the nuclear logo can be used metaphorically for something deadly. The nuclear emoji can mean, "This place poses a great biohazard threat!".

History of the nuclear symbol emoji

The international radiation symbol first appeared in 1946 and is also known as the "trefoil." The symbol emerged at the Berkeley Radiation Laboratory, the University of California. At the time, the symbol was rendered as magenta with a blue background. The original version of the nuclear symbol was used in the United States with a yellow background, drawn with a central circle of radius R shape, an internal radius of 1.5 R, and an external radius of 5 R for its blades divided from each other by 60°. The trefoil was black in the international version and was also used in the United States.

The sign is referred to as a radioactivity warning sign, but it is, in effect, a warning sign of ionizing radiation. Ionizing radiation is a far broader category than radioactivity alone because many non-radioactive sources emit potentially dangerous ionizing radiation levels. It can include x-ray apparatus, particle, and radiotherapy linear accelerators.
