RED Helium is a solid upgrade to the RED Epic Dragon. The Helium's most obvious upgrade from the Dragon is 8K video capture. For example, the Weapon 8K uses the new Helium sensor and can capture 8K video at up to 75 fps (60 fps with RAW high resolution format). The less-expensive Epic W also incorporates the new sensor, and …

Helium makes up about 0.0005% of the earth's atmosphere. This trace amount of helium is not gravitationally bound to the earth and is constantly lost to space. The earth's atmospheric helium is replaced by the decay of radioactive elements in the earth's crust. Alpha decay, one type of radioactive decay, produces particles called alpha particles.
