Characteristics and incorporation monitoring results with a whole body counter

The National Institute for Oncology’s old whole body counter was reconstructed with the following main characteristics; detector: 15 cm dia × 10 cm sodium iodine single crystal, standard chair geometry, in a 20 cm thick iron shield. The detector signals are fed to a 1024 channel analyser. Spectra can be stored on magnetic and/or punched tapes. Punched tape data are used for off-line spectrum unfolding when needed.
