“…In addition, there is also a non-zero, but small neutron flux in the tank that is attributable to (α, n) reactions on light elements and a small amount from spontaneous fission of the transuranic elements. The estimated neutron flux in the tank is on the order of ~2 n/cm 2 /sec [13]. Therefore, it is believed that the contribution to neutron-induced fission of 239 Pu and other elements is small.…”

This report details efforts to develop a technique which is able to detect and quantify the mass of 240 Pu in waste storage tanks and other enclosed spaces. If the isotopic ratios of the plutonium contained in the enclosed space is also known, then this technique is capable of estimating the total mass of the plutonium without physical sample retrieval and radiochemical analysis of hazardous material. Results utilizing this technique are reported for a Hanford Site waste tank (TX-118) and a well-characterized plutonium sample in a laboratory environment.

“…Utilizing the thermalization of neutrons by interactions with hydrogen atoms of water molecules [42,43], neutron activation of materials [44] or photon absorption and Compton scattering of gamma rays [45], radiometric techniques are predominantly applied to soil moisture determination and irrigation scheduling. Most frequently used for monitoring soil moisture are tensiometers [46,47].…”

Based on a short introduction to the dielectric properties of water and aqueous solutions, this review summarizes current techniques of electromagnetic aquametry. The techniques described here include time-domain and frequency-domain procedures, enabling moisture determination in a broad spectral range from millihertz to terahertz frequencies. In this review, quasi-static capacitance and impedance approaches as well as microwave and submillimetre wave reflection, transmission and resonant methods are presented. Sensor configurations and electronic measurement setups, including remote sensing, are discussed briefly. A broad spectrum of applications is introduced to show the extended usability of electromagnetic techniques of moisture content determination. The dielectric properties of some reference materials, suitable for the calibration of sensors and of electronic measurement devices, are tabulated. Reference is also made to some dielectric models of water-containing materials and to superior evaluation routines.
