Abstract
Example apparatus and methods for use in normalization of testing machines used to test samples in vessels are disclosed. An example apparatus includes verification source and a photon emitter positioned in the verification source. The example photon emitter includes a C14 source, a scintillator adjacent to the C14 source, and a filter adjacent to the scintillator. The example photon emitter is to emit photons through the filter for detection by a photon counter.
