[ 1 ] - طراحی و ساخت یک اتاقک یونش با صفحات موازی جهت دزیمتری پرتوهای ایکس تشخیصی

The use of gaseous ionization to calculate the absorbed dose of radiation beams is attractive because of its relative ease, suitable response, high accuracy and also cost-effectiveness. This work introduces the design and fabrication of a new parallel plate ionization chamber with two sensitive volumes. A series of standard tests was performed with x-rays, gamma radiation units, and beta source...

[ 2 ] - طراحی و ساخت اتاقک یونش حلقوی شکل با الکترود های محافظ گرافیتی

The development of a graphite ionization chamber in Iran is reported for first time, using graphite coatings collecting electrodes and guard rings. Its sensitive volume is about 200cm³, with a shape of a ring which is different from its older equivalents and a 7cm central hole that allows the passage of the direct radiation beam without attenuation. This kind of ionization chamber has alre...
