Following their successful first creation of Fluorescent Nuclear Track Detector (FNTD) reader instruments for LANDAUER, Avo Photonics is pleased to announce the development of the second generation instrument featuring improved image quality, faster scanning, and more rugged packaging.
A breakthrough in tools for radiation protection, medical dosimetry, and radiobiology research was achieved in 2005 by LANDAUER with the innovation of FNTD. These wearable badges enable measuring neutron and other particle exposure through imaging of fluorescent tracks induced by radiation in aluminum oxide crystals. Neutrons interact with different converter materials on the top surface of the crystal and thereby produce recoil protons or alpha particles that in turn generate discernible tracks in the volume of the crystal. The FNTD reader instrument consists of an finely tuned and robust optical system based on an automated confocal microscope that images and processes radiation induced tracks and eventually calculates the neutron dose.
With a 30X faster readout, larger detector areas can be scanned with improved counting statistics without sacrificing image quality. This is achieved through a unique line-scanning method, high power laser, and proprietary image and data processing. Moreover, with no moving elements in the optical path the instrument is optically stable and rugged. “It’s exciting to support LANDAUER’s product realization. Their deep history in radiation detection and continuous generation of exciting and better quality tools is impressive,” said Avo’s Optical Program Manager, Dr. Lukasz Maksymiuk. According to Dr. Mark Akselrod, LANDAUER’s Chief Scientist, “Avo’s deep science knowledge and engineering development skills as well as scalable, US-based manufacturing make them a perfect fit for our needs”.
