At NNSA’s labs, plants, and sites, research supporting our vital missions reaches across the electromagnetic spectrum – from radio waves to gamma rays. Sometimes that innovation spills into other areas, too, enabling tomorrow’s technological wonders.
The entire rainbow of radiation that the human eye can see makes up just 0.0035 percent of the spectrum. At NNSA it helps us ensure that we’re working with pure materials, watch for missile launches, and create flat lenses.
The achievement significantly enhances radiological security and underscores NNSA's commitment to keeping America safe from radiological terrorism.
