• TITLE: Field-Strength Depression of Emitters Dispersed from a Point Source into a Cylindrical Volume

  AUTHORS: Palmer G. Steward

  KEYWORDS: Cylindrical Shapes, Radionuclide Emissions, Self-Absorption Component, Dispersion Component, Inverse Square Law

  JOURNAL NAME: Journal of Applied Mathematics and Physics, Vol.9 No.4, April 2, 2021

  ABSTRACT: Dispersing emitters, whose emissions are consistent with the inverse square law, from a point into cylindrical shapes causes a field-strength depression which is strongly dependent upon the cylinder’s dimensions and the distance from the cylinder. The computations of field-strength depressions are partitioned into the components due to dispersion of the emitters alone, due to self-absorption alone, and the total field-strength depression. Each partition is displayed graphically for distances of 5 cm to 10 meters from the cylinders and for a variety of cylinder dimensions. The shape of the displayed curves is analyzed to reveal the basis for correlations between curve shape and the cylinder dimensions. Practical use of the data presented graphically is demonstrated.
