Description
Предиетои изобретени вл етс ионизационна , изолированна от внешней атмосферы камера дл измерени об -излучени материалов.The invention is an ionization, isolated from the external atmosphere chamber for measuring the radiation of materials.
Отличительной особенностью камеры вл етс то, что дл исключени возможности обмена воздуха в камере при смене испытуемых образцов отверогие, через которое радиоактивное излучение проникает в кбшеру, перекрыто заслсниой и открываетс лишь в иоиевф измерений.A distinctive feature of the chamber is that, in order to exclude the possibility of air exchange in the chamber when changing the test samples, the orifice through which radioactive radiation penetrates into the chamber is blocked by the damper and opened only in the course of measurements.
Обычную камеру сС -злектрометра системы ВЛМС укрепл ют в треногом штативе путем зат гивани в ободе штатива днища камеры в котором прорезано отверстие диаметром в 100 ш и укреплена на салазках задвижка из тонкой жести . В нижней части штатива установлена выдвижна тарелочка.7. Положение тарелочки фиксируетс винтом . Дл большей устойчивости штатив устанавливают на металлические,подставки б.A conventional camera of the VLMS system with an electrometer is fixed in a tripod tripod by tightening the bottom of the chamber in which the hole with a diameter of 100 W is cut through the rim of the tripod and mounted on the slide is a tin plate. A sliding plate is installed at the bottom of the tripod. The position of the plate is fixed by a screw. For greater stability, the tripod is mounted on metal, supports b.

ПРЕДМЕТ ИЗОБРЕТЕНИЯSUBJECT OF INVENTION
Ионизационнан кш.ера электрометра дл измерени ct-излучени Ш-териалов , изолирован11а от внешнеИ атмосферы, отличающа с тем. что, о целью исключени обмена воздуха в камере при омеае испытуемых образцов отверстие, через которое радиоактивное излучецие проникает в камеру, перекрыто заслонкой и от-крнваето лишь в момент измерени .An ionization gauge of an electrometer for measuring the CT radiation of X-materials, isolated from the external atmosphere, is different from that. What is the purpose of excluding the exchange of air in the chamber during omeae of the test samples, the hole through which radioactive radiation penetrates into the chamber is blocked by a damper and turns off only at the time of measurement.
