Worker Overexposure

Print View Posted on: 08 November 2024

Event Date: 15 December 2022 Event Type: Radioisotope Processing/Handling Facility Event Location: United States of America, Gilroy, California/ SOFIE INES Rating: 2 (Final)

From September through December of 2022, a radioisotope processing facility had an equipment malfunction that caused syringes filled with Fluorine-18 to miss a shielding container and fall to the floor during production. During this time, workers retrieved the syringes by hand and manually loaded them into the shielded container. This change was not investigated by the radiation safety officer until after the occupational exposures were reviewed. One employee received an annual whole-body effective dose of 0.08 Sv (8.024 rem) which exceeded the U.S. regulatory limit for the annual whole-body effective dose of 0.05 Sv (5 rem). Extremity doses for the employee were below the U.S. regulatory limits. NMED Record 230077.

INES Rating: 2 – Incident (Final) as per 08 November 2024

Submission Window Date(s) (due by 5 p.m. submitting organization’s local time):

NSF recognizes the unique lived experiences of individuals from communities that are underrepresented and/or underserved in science, technology, engineering, and mathematics (STEM) and the barriers to inclusion and access to STEM education and careers. NSF highly encourages the leadership, partnership, and contributions in all NSF opportunities of individuals who are members of such communities supported by NSF. This includes leading and designing STEM research and education proposals for funding; serving as peer reviewers, advisory committee members, and/or committee of visitor members; and serving as NSF leadership, program, and/or administrative staff. NSF also highly encourages demographically diverse institutions of higher education (IHEs) to lead, partner, and contribute to NSF opportunities on behalf of their research and education communities. NSF expects that all individuals, including those who are members of groups that are underrepresented and/or underserved in

Scientists have created a robot that can learn tasks like cleaning a washbasin just by watching humans. A special sponge with sensors is used to show the robot how to clean. Using an advanced machine learning system, the robot learns how it is supposed to behave and can apply this knowledge to cleaning different washbasins.
