Synopsis

NSF is committed to securing the nation’s research enterprise as part of its core mission. The Research on Research Security (RoRS) program will advance the understanding of the full scope, potential, challenges, and nature of the research on research security field through scholarly evidence.

Background

The following activities provide background and context for developing proposals to submit to the RoRS program.

Program Description

Collectively, the research that RoRS funds will foster a broad community that builds collaborations between the STEM research community, research security researchers, and research security practitioners. Interdisciplinary approaches are encouraged, and proposers should address how they will leverage the range of expertise, theories, and methods of the team to engage in evidence-based research on research security. Proposers are encouraged to identify collaborators across a wide range of sectors, and to consider projects in collaboration with international partners that share U.S.

Radiation worker exposure

Print View Posted on: 07 October 2025

Event Date: 13 January 2025 Event Type: Irradiation/Accelerator Facility Event Location: Czech Republic, Nuclear Physics Institute, Praha INES Rating: 2 (Final)

On 13. 1. 2025, the lcencee reported a radiation emergency when an unplanned radiation exposure of a radiation worker occurred. The worker was in the radiation room with a source of ionizing radiation – the Chisostat SO 1 irradiator, which contained a sealed radionuclide source (“URZ”) Co-60 with an activity of 30TBq as of 13. 1. 2025. At the time of the preparatory work, the source was not in a shielded position. The total time the worker spent in the radiation room during 2 entries (7. 1. 2025 and 13. 1. 2025) was about 12.5 minutes.

The investigation found that the last time the irradiator was used on 18. 12. 2024, it was incorrectly turned off. The irradiator was turned off by the main circuit breaker (not via the main control console), therefore the source was not put into the shielded position. It was also found that the backup power source (UPC), which would ensure the insertion of the
