Abstract
Over the past year we have continued our study of the passive standoff detection of radiological materials by Fourier-transform infrared (FTIR) radiometry. The earlier work had shown that a number of radiological materials have an infrared signature in the 8 – 14 µm thermal infrared region. As well, through a series of simulations using the MODTRAN4 atmospheric transmission model, it had been shown that these materials may potentially be detected passively at standoff distances of several kilometres. In this report we present results of our current work that focus on recent new measurements of spectral signatures, including the uranium oxides UO2 and UO3. Preliminary results from a measurement campaign held at Defence Research and Development Canada – Valcartier this year are also presented which address the passive detection of radiological materials in the field at standoff distances of 10 – 40 m. These results are analysed in view of determining the potential for measuring radiological products with a passive standoff FTIR technique.
