ISO 21482 is a technical standard that specifies the design and usage of a "supplemental radiation warning symbol", a warning symbol.It is intended to warn people of the dangers of radiation hazards posed by sealed sources, and encourage the viewer to get away from the source.
English: The new supplementary ionizing radiation warning symbol launched on 15 February 2007 by the International Atomic Energy Agency (IAEA) and the International Organization for Standardization (ISO). Contains radiating waves, a skull and crossbones and a running person, on a red triangle.

The new symbol, to be used on sealed radiation sources, is aimed at alerting anyone, anywhere to the danger of being close to a strong source of ionizing radiation. [13] It depicts, on a red background, a black trefoil with waves of radiation streaming from it, along with a black skull and crossbones , and a running figure with an arrow ...
Medical procedures, such as diagnostic X-rays, nuclear medicine, and radiation therapy are by far the most significant source of human-made radiation exposure to the general public. Some of the major radionuclides used are I-131 , Tc-99m , Co-60 , Ir-192 , and Cs-137 .
Oxygen therapy, also referred to as supplemental oxygen, is the use of oxygen as medical treatment. [1] Supplemental oxygen can also refer to the use of oxygen enriched air at altitude. Acute indications for therapy include hypoxemia (low blood oxygen levels), carbon monoxide toxicity and cluster headache .
the rad (radiation absorbed dose), now replaced by the gray; and; the rem (Röntgen equivalent man), now replaced by the sievert. [25] The rad and rem are essentially equivalent for almost all nuclear medicine procedures, and only alpha radiation will produce a higher Rem or Sv value, due to its much higher Relative Biological Effectiveness ...
