Abstract :
Gamma-ray attenuation is used to measure cryogenic mixture density. Parameters are optimized for specific space application. A simple error formula is established. The feasibility of the measurement is demonstrated. The effect of container´s walls is measured. An automatic measurement device is built. A theoretical calculation is made for the geometry of Ariane V launcher.
