Abstract
An investigation is made into the possibility of applying the long-wave passive standoff detection technique to the identification of radiological materials. This work is based on laboratory measurements of the diffuse reflectance from a number of radiological or related products, including UO2, UO3, U3O8, CoO, Co2O3, IrO2, ThO2, SrO, I2O5, La2O3, and yellow cake. The measured laboratory reflectance signatures were incorporated into the MODTRAN4 radiative transfer model to simulate the nadir radiances of various radiological compounds for three different sensor altitudes. The results of the simulations suggest that passive standoff radiometry may potentially detect and identify radiological materials. Further evidence to support the applicability of the method is based on measurement results from a field trial held at Defence Research and Development Canada – Valcartier involving the passive detection of SrO at standoff distances of 10–40 m.
