A heuristic approach to particle flows in complex terrain

A heuristic approach based on emulating the Navier-Stokes equations is proposed for a shorthand description of flows of airborne particle in complex terrain. The exercise is motivated by the need for a simple, computer-inexpensive, yet comprehensive and flexible model to support a software package on nuclear accident consequence assessment, currently in development at IFA-Bucharest. Central to ...

Aerial Radiation Detection

In this time of multiple threats to our security: dirty bomb; cyber; shooters in public places; homemade bombs; misinformation; etc. we feel extremely vulnerable; perhaps more vulnerable than ever before. With the advent of Drone technology now available to private citizens, technology previously only held by the military, the opportunity has come to marry Drone Technology with aerial sensors. ...

Why is there no effective real-time Continuous Radiation Monitoring System?

Japan's disaster has raised many questions regarding safety of the public. It has served as a wakeup call to the agencies tasked with protecting the public. Not least of these questions, but certainly the most far-reaching is the question of the safety of nuclear power and radiation contamination of air and water. Way back when nuclear power was first established, in the 1960s public opinion was ...

Dredging at weldon spring super fund project Morrison Knudsen - St. Charles, Missouri, USA

Remote controlled Dredging proved to be the best method of removing radioactive sludge from settling ponds of a former uranium processing plant near St. Charles, Missouri. Dredging keeps the material wet and out of contact with the atmosphere throughout the removal and treatment process, eliminating the danger of contaminates becoming airborne. The Weldon Spring Site Remedial Action Project ...

Remote control dredge prevents contamination at Fernald, Ohio nuclear remediation site

When the operations manager at the Fernald, Ohio Super Fund Site Remedial Action Project needed a dredge to remediate sludge from one of four on-site waste (raffinate) pits, they required more than the usual dredging standards. The dredging operation was complicated with the possibility of unknown radon emissions, chemical contamination, and radiation that could be unleashed as material was ...
