| 摘要 |
A composition is formulated with generally regarded as safe (GRAS) ingredients for use as a non-radio-active simulant of radiological contamination such as fallout from a nuclear explosion, particulate from a radiological dispersal device, or contamination from operation of nuclear facilities. The compositions can be used for training exercises, testing, and research studies, and they can be applied safely to human skin. They include an ultraviolet (UV)-excited fluorescent ingredient that makes possible visible viewing of the simulants when illuminated by UV light. The chemical simulants have good fidelity with the physical properties of contamination, for example, adhesion, particle size, electrostatic charging, and response to decontamination technologies such as washing and vacuuming.
