The half-absorption thickness is the thickness of material required to diminish an incident beam of radiation to half its original intensity.The effective thickness of the beta-ray of~(90)Y through soil calculated by the half-absorption thickness is a key parameter of the plastic scintillating fiber array prototype.First,this value was calculated by Monte Carlo simulation with
