A serious, but very uncommon side effect of IL-2 in high doses is capillary leak syndrome or vascular leak syndrome. Capillary leak syndrome is a potentially serious disease in which fluids within the vascular system (veins and capillaries) leaks into the tissue outside the bloodstream.
The electromagnetic spectrum runs from radio waves (the longest wavelength) to gamma waves (the shortest wavelength). In increasing wavelength order, the electromagnetic spectrum is: radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays. In the visible spectrum, violet light has the shortest wavelength.
Gamma-Rays have the highest amount of energy out of any wave. The smaller the wavelength that a wave has the HIGHER the energy the wave has since they are inversely related. The one with the highest frequency, gamma rays. If you imagine the wave as a sine wave, then the wave rises and falls so many times a second. If the freqency is low, the rise and fall are slow. But if the frequency is high, the rises and falls take place much faster. So the higher frequency waves have more energy. The energy of a photon is given by the Plank / Einstein relationship E = h f
