One aspect relates to inducing at least one induced X-ray fluorescing photon at a X-ray fluorescence event within an at least some matter of an at least a portion of an at least one individual responsive to an at least some input energy being applied to the at least some matter of the at least the portion of the at least one individual. The aspect can include detecting the at least one induced X-ray fluorescing photon, wherein the inducing at least one induced X-ray fluorescing photon and the detecting the at least one induced X-ray fluorescing photon is configured to be transported portably as a self-contained and self-powered unit.
