Abstract

Embodiments of the invention relate to a method and apparatus for detecting an isotope. Specific embodiments can detect radioactive isotopes. Embodiments of the invention can utilize a detector that incorporates at least two sub-detectors. Each sub-detector can receive energy from an isotope and create a signal corresponding to the received energy. Each sub-detector can incorporate a detector element, such as a detector element incorporating one or more diodes, a detector element incorporating a crystal, a detector element incorporating a solid-state device, or a detector element incorporating a scintillator. The sub-detectors can be configured such that for each isotope to be detected at least two of the sub-detectors produce different output signals, or readings. In a specific embodiment, each sub-detector is configured such that when there are at least two sub- detectors exposed to the isotope each of the corresponding readings from the sub-detectors are different from each of the other readings. The different readings of the sub-detectors for the same isotope can be due to a filter being placed between the isotope being detected and one of the sub-detector's detector element; due to using detector elements with different detector materials, different detector designs, or other detector element differences; or other differences that produce different readings for the same radioactive isotope.
