Radioactive core samples containing elevated concentrations of Cr from a high level nuclear
waste plume in the Hanford vadose zone were studied to asses the future mobility of Cr. Cr …

137Cesium and other contaminants have leaked from single-shell storage tanks (SSTs) into
coarse-textured, relatively unweathered unconsolidated sediments. Contaminated …

Laser atomic absorption was used to measure the rubidium isotopes in a laser-induced
plasma. An 85Rb/87Rb isotope ratio of 2.7±0.2 was determined in solid calcium carbonate …

An autoradiographical method using an imaging plate (IP) was developed to identify rapidly
the density of plutonium (Pu) particles on filter samples. Photostimulated luminescence …

Nuclear waste that bore 90Sr2+ was accidentally leaked into the vadose zone at the
Hanford site, and was immobilized at relatively shallow depths in sediments containing little …

As part of the recent developments of digital autoradiography-based methods in the context
of nuclear dismantling (alpha and soft-beta on-site detection, mapping, wastes and sample …

In the environment, artificial radionuclides exist in various mobile and non-mobile forms.
One of the most kinetically stable radionuclides forms is so-called “hot” particles which could …

We have been exploring ways to evaluate the activity of radioactive particles that have been
detected by phosphor plate digital autoradiography based on photostimulated luminescence …

Modern autoradiography techniques based on phosphorimaging technology using image
plates (IPs) and digital scanning can identify heterogeneities in activity distributions and …

An autoradiographical method using an imaging plate (IP) was developed to analyze
plutonium contamination in a plutonium handling facility. The IPs were exposed to ten …
