http://www.hep.fsu.edu/~berg/teach/phy2048/1202.pdf WebAfter hydrogen, helium is the second most abundant element in the universe. It is present in all stars. It was, and is still being, formed from alpha-particle decay of radioactive elements in the Earth. Some of the helium formed escapes into the atmosphere, which contains about 5 parts per million by volume. simply b 取扱説明書
