Des nanotubes pour filtrer les ondes parasites

A manufacturer of injection nozzle used carbon nanotubes to develop a nuclear radiation detector of small, accurate and reliable. This tool will detect radiation through a scintillator, a crystalline material which emits light when exposed to radiation.
To prevent the scintillator to respond to other sources of radiation (eg electromagnetic) the opening is covered by a layer of plastic was mixed carbon nanotubes the thickness of a sheet of paper.
This layer will help to block radio waves, visible light and other sources of electromagnetic wave so that the scintillator does not perceive that nuclear radiation.
