This might be a very stupid question :(, but I am confused.
So I did an experiment.
we had radioactive material which was emitting beta particles, and we were using geiger counter to measure pulses (ionized beta particles). We were supposed to measure the time it takes for the geiger counter to reach 1000 pulses and time difference by adding aluminum foils (thicker aluminum foil = longer time).
I am confused about two things,
-How it is possible that aluminum foil is able to stop beta particles? (what happens to beta particles in aluminum(are they just reflected from aluminum nucleus or can they become also outer-shell electron of aluminum atom, can beta particle get ionized in the aluminum foil (steal an electron from aluminum atom)?
-Are ionized beta particles dangerous? (ionized alpha particle are not because they become helium, what happens with beta particles?)
