10 Leren hanteren van agressie, 1929, the German literature usually referred to cosmic rays as . (ultra-gamma radiation). The reason is that the most penetrating radiations known at those times were the gamma rays from radioactive substances. Indeed, the mean free path of gamma ray photons emitted by these substances in air were

The latter was principally made using particle accelerators which allow studying easily in the laboratory of the different interactions by

5 Als een meningsverschil escaleert,The researches described until now regarded the nature of cosmic rays on the Earth, but had given no direct information on the nature of the “primary” cosmic rays that are falling on the Earth from outside. This information came from the study of new effects, due to the presence of the Earth’s magnetic field.
