Title: The Innovative Contributions of Robert J Gehrke

Introduction

Robert J Gehrke is a notable inventor based in Idaho Falls, ID (US). He has made significant contributions to the field of spectroscopic analysis, particularly in the detection of plutonium and other radioactive materials. His innovative methods have implications for environmental safety and nuclear material monitoring.

Latest Patents

Gehrke holds a patent for a method of photon spectral analysis. This spectroscopic method allows for the rapid measurement of plutonium presence in various materials, including soils, filters, smears, and glass waste forms. The technique utilizes uranium L-shell x-ray emissions associated with plutonium decay to acquire spectra and analyze the amounts of americium and gamma-ray emitting activation and fission products present. His method employs a large area, thin-window, n-type germanium spectrometer, which is efficient for detecting both low-energy x-rays (10-2000 keV) and high-energy gamma rays (>1 MeV). The entire photon spectrum is acquired using a 8192- or 16,384 channel analyzer, ensuring comprehensive analysis.
