Investigators publish new report on Ro botics. According to news reporting out of Corvallis, Oregon, by NewsRx editors, research stated, "The maturation of robotic and remote systems presents opportu nities to expand the use of technologies that have typically been restricted to high-dose/high-risk nuclear work for moderate- or low-risk work to further reduc e radiation exposure to workers. This study quantifies the potential dose saving s achieved through the use of robotic techniques for characterizing transuranic- contaminated waste items and compares dose estimates from a simplistic, user-fri endly deterministic radiation transport code and a more robust, complex Monte Ca rlo code." Financial support for this research came from Oregon State University. Our news journalists obtained a quote from the research from Oregon State Univer sity, "Three scenarios of transuranic-contaminated waste items described in publ ished reports are modeled using representative source geometries in MicroShield and MCNP radiation transport codes. Estimated dose rates are determined at point s ranging from 30 cm to 300 cm from the face of the waste item to represent the increase in distance allowed by robotic or remote system implementation for char acterization activities. The dose rate savings are then converted to detriment c ost savings using a dollar-per-person-dose conversion factor to provide a financ ial context. The radiation transport simulations show no consistent bias in esti mated dose rate by varying simulation methodology or using geometrical simplific ations-in some cases, MicroShield produces higher dose rate estimates while MCNP estimates are higher in other cases. In the MCNP simulations, the volume source geometry consistently produces a higher dose rate than the slab source geometry , but the MicroShield dose rate estimates do not display the same trend."
