The gold standard in irradiation dosimetry

Bruker delivers the complete gold standard radiation dosimetry system

EPR has long been used as a quantitative tool to study the effects of radiation. Ionizing radiation produces free radicals in many forms of matter that can be quantitatively detected by an EPR spectrometer, resp. EPR dosimetry.


The EPR spectrometer works by measuring energy level transitions of unpaired (free) electrons at a specific resonant frequency within a variable magnetic field.

Features

Alanine forms a very stable free radical when subjected to ionizing radiation. The alanine free radical yields an EPR signal that is dose dependant, yet is independent of the dose rate and energy and is relatively insensitive to temperature and humidity. Thus, alanine dosimetry is equally suited to Gamma, E-beam, or X-ray irradiation facilities. Alanine dosimeters are available as pellets or films depending on the application.

  • 1% accuracy or better
  • Dose rate independent
  • Detection limit below 1 Gray
  • Accurate from 10 Gray to 200 kGy
  • Bar code reader for sample archiving
  • Compatible with ISO/ASTM51507

Bruker is proud to introduce a new dosimetry system that combines the e-scan alanine dosimeter with the BioMaxTM Alanine Dosimeter Film. The e-scan is an easy-to-use benchtop EPR spectrometer that provides a rapid and accurate dose measurement for either alanine film or pellet dosimeters. The barcoded BioMax Film not only provides KodakTM quality, but furthermore allows for the automation of several routine functions (i.e. sample/batch identification, sample position and measurement initiation).

Rapid, Secure Dose Determination

The e-scan provides a simple automated routine for measuring either alanine film or pellet dosimeters. The e-scan software is simple and intuitive, yet comprehensive.
