摘要： A charged particle measuring apparatus which can discriminate the types of charged particles accurately and the energy precisely, measure high-energy charged particles precisely, and detect a failure of the measuring apparatus to continue measurement in a mode corresponding to the failure. The output from a first detector is used as a first address. The output from a second detector consisting of a plurality of detectors is used as a second address. The output from a third detector is used as information about whether or not certain charged particles penetrate the second detector. The loss energy characteristics of charged particles to be measured are expressed in the two-dimensional addresses mentioned above. The numbers of times the charged particles are measured for loss energy are counted with respect to each of the two-dimensional addresses. In addition, when the series of detectors constituting the first through third detectors suffers a failure, a measurement mode for excluding the failed detector(s) is employed to continue measurement.

摘要： Method and apparatus for counting nuclear scintillations particularly the activity in a specimen containing tritium segregates the pulses which are emitted from a scintillator due on interaction with a nuclear particle from the pulses attributable to random noise. The system uses a single photomultiplier (12), the output of which is split among a two-path circuit (22, 32). A pulse height analyzer (46) provides an output when one path (32) has an integrated output signal of preselected amplitude when the other path (22) output has a preselected number of component photon response pulses occurring in a preselected period of time. The system is operable with many scintillation materials as long as the characteristic output from the scintillator is long relative to the duration of a random noise pulse. The preferred embodiment incorporates a solid scintillator although a liquid material may be substituted if the functional criteria are satisfied. Also discussed is the response of an apparatus in accordance with the present invention if some relatively high energy isotopes such as carbon-fourteen are tested.

摘要： A method of identifying radioactive components in a source comprising (a) obtaining a gamma-ray spectrum from the source; (b) identifying peaks in the gamma-ray spectrum; (c) determining an array of peak energies and peak intensities from the identified peaks; (d) identifying an initial source component based on a comparison of the peak energies with a database of spectral data for radioactive isotopes of interest; (e) estimating a contribution of the initial source component to the peak intensities; (f) modifying the array of peak energies and peak intensities by subtracting the estimated contribution of the initial source component; and (g) identifying a further source component based on a comparison of the modified array of peak energies with the database of spectral data. Thus a method for identifying radioactive components in a source is provided which does not rely on comparing template spectra with an observed spectrum.

摘要： An apparatus for measuring neutrons and gamma rays is disclosed in which after pulses generated by neutrons are discriminated from pulses generated by gamma rays, two different counted values are obtained (24, 26) for either the pulses generated by neutrons or the pulses generated by gamma rays to control a discriminating circuit between the pulses by neutrons and the pulses by gamma rays so that a ratio between the different counted values is kept constant, and further two different counted values are obtained for either the pulses by neutrons or the pulses by gamma rays in a manner (24, 30) same as the above-mentioned to control the output of a detector (10, 12) so that a ratio between the counted values is kept constant.
