Description

Известные способы измерени  разности ионизирующих излучений используют методы модул ции, основанные на применении динамических конденсаторов и контактных вибропреобразователей с последующим усилением сигналов иа переменном токе. Однако динамические конденсаторы и вибропреобразователи обладают р дом недостатков, снижающих точность измерений.The known methods for measuring the difference in ionizing radiation use modulation methods based on the use of dynamic capacitors and contact vibration transducers with subsequent amplification of signals by alternating current. However, dynamic capacitors and vibration transducers have a number of disadvantages that reduce the accuracy of measurements.

Предлагаемый способ не имеет этих недостатков ввиду того, что механические модул торы не при1мен ютс . При измерении исиольз етс  разностный сигнал переменного тока, получаемый путем питани  ионизационных камер знакоперемепным напр жением. РЬмерение разности потоков ионизирующего излучени  осуществл етс  по схеме, изображенной на чертеже.The proposed method does not have these drawbacks due to the fact that mechanical modulators are not used. When measuring, an AC difference signal is used, which is obtained by supplying ionization chambers with alternating voltage. The measurement of the difference in the fluxes of ionizing radiation is carried out according to the scheme shown in the drawing.

Папр жение переменного тока подводитс  от обмотки трансформатора / к двум однотипным ионизационным камерам 2, средн   точка обмотки заземл етс . Оба собирающих электрода соедин ютс  вместе и через высокоомное сопротивление 3 нагрузки камер заземл ютс . Ьсли обе камеры облучаютс  одинаково, то выходной сигнал частоты питани  на нагрузке равен нулю; различие в облучении вызывает по вление сигнала на нагрз-зке, амплитуда и фаза которого завис т от оолучени  камер.The alternating current is fed from the winding of the transformer / to two ionization chambers of the same type 2, the middle point of the winding is grounded. Both collecting electrodes are connected together and through the high resistance resistance of the load cells 3 are grounded. If both chambers are irradiated in the same way, then the output frequency of the power supply at the load is zero; The difference in irradiation causes a signal to appear on the load, the amplitude and phase of which depend on the acquisition of the chambers.

Предтагаемый способ может быть использован дл  приборов, измер ющих с помощью радиоактивных излучений толщины материалов, плотности жидкостей и пульп, а также и в других устройствах, где необходимо сравнивать потоки излучений. Во всех этих случа х может быть использован усилитель переменного тока, на вход которого подаетс  сигнал переменного тока, снимаемый с нагрузки камер.The proposed method can be used for devices that measure the thickness of materials, the density of liquids and slurries with radioactive radiation, as well as in other devices where it is necessary to compare radiation fluxes. In all these cases, an AC amplifier can be used, to the input of which an AC signal is taken from the load on the cameras.
