An accurate and precise film dosimeter for radiation processing, materials testing and related research and development
Cellulose Triacetate (CTA) Dosimeter
for Dosimetry in Electron Beam, Gamma-ray and Ion Beam Irradiations.
CTA dosimeter is an accurate and precise film dosimeter of which the optical density increases by radiation exposure. It is most suitable for radiation processing, materials testings and related various research and development.
Characteristics
•Linear dose response
•Simple measurement procedure
•High spatial resolution
•Applicable to ion beam dosimetry
Features
Accurate and precise dosimetry is essential to quality control in industrial radiation processing and R&D using radiation from large radionuclide and machine sources. CTA dosimeter, FTR-125, has been developed for routine dosimetry in these fields. The optical density of the dosimeter film increases linearly with absorbed dose for electron beams, gamma-rays, and ion beams. Since the dosimeter is in the shape of a thin long tape, it allows to accurately and conveniently measure dose distributions on the surface of irradiated samples and depth-dose distributions in the samples with high spatial resolution.
