Property Value
dbo:abstract
  • A lung counter is a system consisting of a radiation detector, or detectors, and associated electronics that is used to measure radiation emitted from radioactive material that has been inhaled by a person and is sufficiently insoluble as to remain in the lung for weeks, months, or years. Often, such a system is housed in a whose thick walls will be made of low-background steel (~20 cm thick) and will be lined with ~1 cm of lead, then perhaps thin layers of cadmium, or tin, with a final layer of copper. The purpose of the lead, cadmium (or tin), and copper is to reduce the background in the low energy region of a gamma spectrum (typically less than 200 keV) (en)
