Scintillators

Environmentally friendly, highly sensitive products suitable for non-destructive testing

Scintillators

Product Information

Outline

Scintillators are used in the detectors of various X-ray systems, including cargo screening systems, contamination inspection systems, analysis equipment, and radiation detection equipment. Toshiba's scintillators contribute to faster inspections and improved resistance to humidity. In addition to the above, we are able to make various proposals depending on on customer's applications.

X-ray systems

Advantages

  • High sensitivity combined with short decay time and low afterglow
  • Eco-friendly material containing no hazardous substances
  • Good resistance to humidity

Intensifying screens and Fluorescent screens

Supporting medical care with high sensitivity and high definition

Intensifying screens and Fluorescent screens

Outline

Intensifying screens are made of highly sensitive phosphors and used with photofluorography. When we are X-rayed, they reduce irradiation to one hundredth of the ordinal irradiation without intensifying screens.

Advantages

  • Our intensifying screens have high sensitivity and high sharpness by our technology that makes a high-density phosphor layer and prepares optimal grain size distribution.
  • Sensitivity and sharpness are further improved by our structural designing that ensures effective light reflection and X-ray absorption characteristics.
  • The surfaces of intensifying screens are protected with a special film to prevent darts and scars and to render handling easy.

Types and phosphor materials of intensifying screens

  • TO-type screens use gadolinium oxisulfide with terbium (Gd2O2S:Tb) for orhto-type phosphor emitting green light. (Toshiba Ortho Type)
  • E- and D-type screens use calcium tungstate (CaWO4) emitting blue light.
  • Q-type screens use barium fluoro chloride with europium (BaFCl:Eu) emitting blue light.
