Does Gravity Affect Beta Particle Absorption in Aluminium Foils?

Click For Summary
SUMMARY

The discussion centers on the impact of gravity on the absorption of beta particles by aluminum foils during experiments using a Geiger-Müller scintillator. It concludes that gravity is negligible in these particle experiments conducted at sea level, as there is no observable difference in beta particle absorption when the source and detector positions are switched. The primary interaction occurs between beta particles and atomic electrons, with minimal influence from atomic nuclei through bremsstrahlung interactions.

Suppose a beta particle source. Using a G.M. scintillator and several aluminium foils we can find the absorption of aluminium on beta particles. Does the absorption of aluminium changes by placing aluminium foils over or under the radioctive source? Considering for example gravity. Does gravity significantly affect this procedure?

gravity is neglectable when we do particle experiments on this sea level.
 
The beta particles interact with the atomic electrons primarily. One could place the source above with detector below, and then switch the detector above and source below. One will notice no difference for the same Al thickness.

The beta particles simply lose energy/momentum when colliding with atomic electrons. There is some interaction with the nuclei, which is termed brehmsstrahlung interaction.
