Vita Radiation is electromagnetic radiation with a specific wavelength that has stabilizing properties. It was used to activate the properties of the Super Soldier Serum in Steve Rogers and is present in Nitramene.
During his transformation into the first super soldier, Steve Rogers screamed in pain as his body absorbed a vita radiation level of seventy percent. Peggy Carter and Erskine wanted to stop the project; however, Rogers begged them not to cease, saying that he could take it. Howard Stark proceeded to increase the output to a hundred percent, causing the chamber to glow so brightly that Chester Phillips and other observers covered their eyes.
Vita radiation does not last long on people, but objects, such as watches and civilian clothing, hold the radiation longer.
