Novel Radiation Detector Based on a Metal

In spite of the advancements on radiation detectors, there are not, so fa rreported, radiation detectors based on solid metals. Here is the design,construction, characterization, and operation of a novel radiation detector,based on an Aluminum 7 cm × 7 cm × 0.20 cm plaque. When this detector is exposed to natural radiation, cosmic rays, in horizontal position, with an applied electric field between 0 Vdc/cm and | ±4000 | Vdc/cm, there are no detected pulses (triggers); the pulses start to appear above | ±4000 | Vdc/cm, and with |±40 | mV of oscilloscope trigger level. This radiation detector was tested extensively over many possibilities on the origin of these randomly produced pulses. All the collected information is consistent with that the pulses are produced by cosmic ray hits; therefore, this is a novel technique based on a metal, to detect ionizing radiation, in particular cosmic rays.
