High precision isotopic study of atmospheric helium : volcanic and environmental applications

The helium isotopic composition of air (RA = 3He/4He = 1.39 × 10-6) is related to the natural and anthropogenic fluxes of 3He and 4He from the Earth (and from space for 3He). Industrial activities emit gases enriched in radiogenic 4He (exploitation of fossil fuels) and in 3He (nuclear activities). I...
