A Low-Cost, Compact, FPGA-Based Gamma Spectrometer for Mobile Applications

Summary

 

Technology Description

 

This spectrometer uses a Csl(Ti) scintillation crystal coupled to a solid-state photomultiplier to detect radiation interaction and an on-board 40 MHz, 12-bit digital pulse-processor based on a field-programmable gate array that generates an energy histogram. The device has a wireless connectability function that allows mobile phones to display the collected data.

 

Features & Benefits

 

  • Low-cost personal dosimeter
  • Compact device easily useable by consumers
  • Device able to achieve 5.66% FWHM energy resolution at 662 keV
  • Battery small enough to be powered by mobile phone

 

Applications

 

  • Radiation detection
  • Personal dosimetry
  • Battlefield assessment
  • Emergency response

 

Background of Invention

 

There is a significant role in emergency response and personal radiation safety that can be played by a compact radiation detector that is capable of identifying radionuclides. The current state of the art features no current handheld spectroscopy performance that is compatible with a cellular phone. Researchers in the Advanced Radiation Instrumentation Laboratory at Oregon State University have created a small, low-cost, low-power gamma ray spectrometer to fill this role.

 

Status

 

Prototype has undergone extensive successful laboratory testing.
