    • The invention includes an ionizing radiation detector which includes a chamber within a housing. A receiving member within the chamber has a plurality of spaced holders for receiving samples. The samples are maintained in an array of substantially parallel samples with the samples functioning as electrodes within the chamber. The invention includes a method of counting emissions from samples. An odd number of electrodes are introduced into a detector chamber. Each of the electrodes includes at least one sample to be analyzed. The electrodes are organized into an array of substantially parallel electrodes, each electrode being in electrical communication with a contact surface. The electrode array includes cathodes and anodes where the number of cathodes differs from the number of anodes by one. A voltage is applied across the electrodes and particle emission is detected from the samples based upon ionization of counting gas within the chamber.
    • 本发明包括电离辐射检测器,其包括在壳体内的腔室。 室内的接收构件具有用于接收样品的多个间隔开的保持器。 将样品保持在基本上平行的样品的阵列中,其中样品用作室内的电极。 本发明包括对来自样品的排放物进行计数的方法。 将奇数个电极引入检测器室。 每个电极包括至少一个要分析的样品。 电极被组织成基本平行的电极的阵列,每个电极与接触表面电连通。 电极阵列包括其中阴极数与阳极数不同的阴极和阳极。 在电极之间施加电压,并且基于室内的计数气体的离子化从样品中检测出颗粒发射。
