  Code	Display	Definition
  128703	Ion Chamber Array	A number of devices that measures charge from the ions produced in a medium when exposed to ionizing radiation. The devices are arranged systematically in a regular pattern.
  128702	Diode Array	A number of semiconductor devices that generates current when exposed to ionizing radiation. The devices are arranged systematically in a regular pattern.
  128705	Liquid Ion Chamber	An ion chamber that uses a liquid as the medium.
  128704	Diode	A semiconductor device that generates current when exposed to ionizing radiation.
  128707	Ion Chamber	A device that measures charge from the ions produced in a medium when exposed to ionizing radiation.
  128706	OSLD	Optically Stimulated Luminescent Dosimeter. It is a crystal that when exposed to green light, emits blue light in proportion to the amount of ionizing radiation it has been exposed to.
  128709	RPLGD	A radiophotoluminescence glass dosimeter. It is a solid state cumulative radiation dosimeter usually made of silver-activated phosphate glass. The silver atoms act as radiophotoluminescence centers excited by ionizing radiation. The number of centers excited is proportional to the absorbed dose to the RPLGD.
  128708	Diamond Detector	A semiconductor detector that uses diamond as the medium.
