The influence of the geometry has been investigated; experiments have been performed for

qualitative determination of the effect of Experiment Geometry On beta-ray absorption coefficient.

It has been demonstrated that the reduction in the number of beta-particles transmitted through

absorbers is due mainly to the process of deflection from initial direction. The investigations have

been performed using the beta radioactive source Sr( Y) 39 90 38 90, and scintillation detector with stilbene

crystal. An emperical relation for the number of beta-particles transmitted through an absorber,

which accounts for the geometry and the contribution of scattered electron has been tested.
