Предложена схема измерений, основанная на использовании локальной области входного окна ионизационной камеры. Определены средние углы рассеяния в пленках полиэтилентерефталата. Предложено техническое решение, позволяющее более чем в 3 раза снизить погрешность измерений радиоизотопного плотномера. </p></abstract><trans-abstract xml:lang="en"><p>The experimental investigations of spatial energy distribution for beta particles in a measuring gap of a basis weight sensor are described. We propose the measurement procedure, which employs a local domain of the ionization chamber input window. The average scattering angles in polyethylenterephtalate films are determined. Suggested technical solutions allow more then three times to reduce the error of measuring of radioisotope densitometer.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бета-частицы</kwd><kwd>радиоизотопный плотномер</kwd><kwd>измерительный зазор</kwd><kwd>полиэтилентерефталат (ПЭТФ)</kwd></kwd-group><kwd-group xml:lang="en"><kwd>beta-particles</kwd><kwd>basis weight sensor</kwd><kwd>measurement gap</kwd><kwd>polyethylenterephtalate (PETF)</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Vapirev, E.
