Abstract

FIELD: physics.
SUBSTANCE: device for calibrating and verifying dosimeters consists of a balance arm, a post on which a gate is mounted, the post resting on the end of the balance arm which is balanced by a load and is pivotally connected to a bar, which is also pivotally connected by the other end to the housing of a lead container at a certain angle which provides tight adjoining of the gate to the surface of the container. The device is actuated by a crank mechanism and a pusher which is connected to the crank mechanism and corresponding hinges to the balance arm; the shaft of the crank mechanism is actuated by a lever by manually turning it 180 degrees.
EFFECT: wider field of use, high accuracy of dose measurements, providing radiation safety.

Description

На дозиметрических поверочных установках, как, например, УПГД-2, УКПН 1М и др., заслонка, перекрывающая пучок ионизирующего излучения, открывает или закрывает коллиматор, в котором располагается источник ионизирующего излучения (например, кобальт-60 или цезий-137 и др.), за продолжительное время (около 20 с), что существенно влияет на процесс набора дозы и вносит дополнительно погрешность.At dosimetric calibration facilities, such as UPGD-2, UKPN 1M, etc., a damper that blocks the ionizing radiation beam opens or closes the collimator, in which the ionizing radiation source is located (for example, cobalt-60 or cesium-137, etc. ), for a long time (about 20 s), which significantly affects the process of dose collection and introduces an additional error.

Изобретение относится к области поверки и градуировки радиометров и дозиметров при их массовом производстве. Цель изобретения - расширение области применения, повышение точности измерений дозы, обеспечение радиационной безопасности.The invention relates to the field of calibration and calibration of radiometers and dosimeters in their mass production. The purpose of the invention is the expansion of the scope, improving the accuracy of dose measurements, ensuring radiation safety.

Предлагаемое устройство, изготовленное автором, успешно эксплуатируется на приборостроительном заводе уже много лет и обеспечивает открывание и закрывание защитной заслонки весом 200 кг за доли секунды при помощи соответствующего рычага, приводимого вручную поворотом на 180 градусов. Прилагаемые усилия ничтожны.The proposed device, manufactured by the author, has been successfully operated at the instrument-making plant for many years and provides the opening and closing of the protective damper weighing 200 kg in a split second using the corresponding lever, manually driven by 180 degrees. The efforts are void.

На рисунках 1 и 2 изображены положения заслонки (7), когда коллимационный узел закрыт (рис.1) и когда он открыт (рис. 2). На рис.1 (10) указан радионуклид, используемый в установке. Устройство, обеспечивающее закрывание и открывание заслонки, состоит из коромысла (1), стойки (2), на которой крепится заслонка (7). Стойка (2) опирается на конец коромысла (1), уравновешенного грузом (6), и шарнирно соединена со штангой (3), которая другим концом так же шарнирно соединена с корпусом свинцового контейнера (8) под определенным углом, обеспечивающим плотное примыкание заслонки (7) к поверхности контейнера.Figures 1 and 2 show the positions of the shutter (7) when the collimation unit is closed (Fig. 1) and when it is open (Fig. 2). Figure 1 (10) shows the radionuclide used in the installation. The device for closing and opening the shutter consists of a rocker arm (1), a stand (2), on which the shutter (7) is mounted. The stand (2) rests on the end of the beam (1) balanced by the load (6) and pivotally connected to the rod (3), which is also pivotally connected to the body of the lead container (8) at a certain angle, ensuring a tight fit of the shutter ( 7) to the surface of the container.

При открывании заслонки (7) образуется небольшой зазор (2 мм) между стойкой (2), на которой укреплена заслонка (7). Это положение изображено на рис.2.When opening the shutter (7), a small gap (2 mm) is formed between the stand (2), on which the shutter (7) is mounted. This position is shown in Fig. 2.

Все устройство приводится в действие при помощи кривошипного механизма (4) и толкателя (9), связанного с кривошипным механизмом, соответствующими шарнирами с коромыслом (1). Ось кривошипного механизма приводится в действие при помощи рычага (5) путем его поворота на 180 градусов вручную при приложении небольшого усилия.The whole device is driven by a crank mechanism (4) and a pusher (9) associated with the crank mechanism, the corresponding hinges with the beam (1). The axis of the crank mechanism is actuated using the lever (5) by turning it 180 degrees manually with little effort.
