Radiactive Waste Facility Taken Over

Print View Posted on: 19 March 2025

Event Date: 02 March 2025 Event Type: Radiation Waste Facility Event Location: Mexico, Temascalapa, Mexico State, Mexico INES Rating: 0 (Final)

On Sunday March the 2nd, 2025, at approximately 6:30 AM (UTC-06:00), personnel from the municipality of Temascalapa forcibly took over the Low and Medium Level Radioactive Waste Storage Center (CADER), property of the National Institute of Nuclear Research (ININ), evicting the personnel who were at the facility and subsequently placing seals of closure at the entrances. The video surveillance and environmental radiation monitoring systems that CADER has were disabled and there was no way to know the status inside the Center.
Negotiations took place out between personnel from the government of the State of Mexico and the Municipality of Temascalapa, without reaching agreements so far.
In addition to the radioactive material and depleted uranium that are kept in the facility, work tools from a foreign company were also retained inside it.
Federal Authorities were working to regain control of the facility. The source term of the facility is estimated at approximately 1,041.55 TBq of Co-60 and its surface area is

Event Date: 06 March 2025 Event Type: Radiation Source Event Location: United States of America, Mentone, Texas / National Inspection Services, LLC INES Rating: 1 (Final)

On March 6, 2025, a radiography crew working approximately 16 km (10 mi) east of Mentone, Texas, reported losing a SPEC 150 exposure device containing a 3.53 TBq (95.4 Ci) iridium-192 source.

Update: On March 13, 2025, a member of the public contacted the licensee stating they had found the exposure device. The device was recovered by and is in the possession of the licensee. The device had remained in a locked shed since being found. The exposure device was found to be intact and no attempt was made to operate or tamper with the device. Exposure levels were normal and no individual would have received any significant exposure due to this event.

Chainmail-like polymer could be the future of body armor

Researchers supported by grants and instrumentation provided by the U.S. National Science Foundation have created the first 2D polymer material that mechanically interlocks, much like chainmail, and used an advanced imaging technique to show its microscopic details. The material combines exceptional strength and flexibility and could be developed into high-performance and lightweight body armor that moves fluidly with the body as it protects it.

The nanoscale material was developed by researchers at Northwestern University and the electron microscopy was conducted at Cornell University. The results are published in a paper in Science.

The microscopic structure of a two-dimensional, mechanically interlocked polymer captured using an advanced electron microscopy technique.

Groundbreaking in more ways than one, the paper describes a highly efficient and scalable polymerization process that could potentially yield high volumes of this material at mass scale. In addition to being the first 2D mechanically interlocked polymer, it also contains 100 trillion mechanical bonds per 1 square centimeter — the highest density of mechanical bonds ever achieved in a material.    

“We made a completely new polymer structure,” says William Dichtel, a researcher at Northwestern University and one of the study’s authors. “It’s similar to chainmail in that it cannot easily rip because each of the mechanical

Synopsis

Strengthening American Infrastructure (SAI) is an NSF program seeking to stimulate human-centered, use-inspired, fundamental and potentially transformative research aimed at strengthening America’s infrastructure. Effective infrastructure provides a strong foundation for socioeconomic vitality and broad improvement in quality of life. Robust, reliable and effective infrastructure spurs private-sector innovation, grows the economy, creates jobs, makes public-sector service provision more efficient, strengthens communities, promotes equal opportunity, protects the natural environment, enhances national security and fuels American leadership. Achieving these objectives requires the integration of expertise from across all science and engineering disciplines. SAI focuses on how fundamental knowledge about human reasoning and decision-making, governance, and social and cultural processes enables the building and maintenance of effective infrastructure that improves lives and society and builds on advances in technology and engineering. Successful projects will represent a convergence of expertise in one or more social, behavioral or economic
