Betas' Ionization without the FR4 shutter

Beta particles are emitted from U-233 radioactive isotope, their energy spectrum vs the percentage of the emitted bata is shown in the figure below:

A simulation for beta ionization is performed using G4.9.6-p02, example TestEm10 helped in evaluating the number of primary and the secondary electrons in the drift region.



The figure above shows the number of the primary electrons of betas' ionization in 1 cm of Ar/CO2 90/10.
