  • Patent number: 5012108
    Abstract: A method of detecting, counting or otherwise measuring nuclear radiation includes the steps of exposing a diamond containing single substitutional paramagnetic nitrogen to the nuclear radiation to cause electrons or holes to be trapped at lattice imperfections within the diamond crystal structure, heating the diamond to cause it to luminesce and utilizing the luminescence as a means for the detection, counting or measurement of the nuclear radiation. The method is characterized by subjecting the diamond to a high dose of neutron or electron irradiation prior to exposing it to the nuclear radiation to be detected. This, it has been found, improves both the sensitivity of the diamond as a thermoluminescent material and linearity of the thermoluminescent response to nuclear radiation dose.
