South Korean Study Confirms Low-Dose CT Arthrography Reduces Radiation Exposure in Shoulder Examinations

A research team led by Professor Choi Jeong-ah from the Department of Radiology at Hallym University Dongtan Sacred Heart Hospital in South Korea has recently confirmed that low-dose CT arthrography can reduce patient radiation exposure by approximately 31% while maintaining high diagnostic accuracy, with diagnostic performance comparable to 3T magnetic resonance imaging (3T MRI). The findings have been published in the international musculoskeletal imaging journal *Skeletal Radiology*. Rotator cuff tears and superior labral anterior-posterior (SLAP) lesions are significant causes of shoulder pain; if not diagnosed and treated in a timely manner, they may lead to arthritis or decreased shoulder joint function. Currently, 3T MRI is commonly used for precise examinations, but it has drawbacks such as high cost, long examination times, and the potential for claustrophobia in some patients;...

International Students of the "Chinese Government Atomic Energy Scholarship" Program Visit China Isotope & Radiation Corporation

On July 22 and July 29, over 50 international students from more than 10 countries, including Egypt, Pakistan, Ethiopia, Ghana, the Philippines, Cambodia, Mongolia, Bangladesh, Namibia, Nigeria, El Salvador, Sudan, Yemen, and Russia, who are part of the Chinese Government Atomic Energy Scholarship program, visited China Isotope & Radiation Corporation (CIRC). They experienced firsthand the vibrant vitality of China's nuclear technology application industry, enhancing their understanding and recognition of China's nuclear industry through tours and exchanges. First Stop: Atomic High-Tech Jinhui Radiation - When Nuclear Technology Enters Daily Life. The students visited Atomic High-Tech Jinhui Radiation to learn about the extensive applications of irradiation technology in medical sterilization, food preservation, aerospace testing, and other fields, and observed relevant process flows. A student from Pakistan exclaimed, "I never imagined irradiation technology had penetrated so deeply into various fields. This has given me a completely new understanding of the breadth of China's nuclear technology applications." The students engaged in lively interactions with technical staff on topics such as the safety and application prospects of irradiation technology.

Ministry of Ecology and Environment's North China Nuclear and Radiation Safety Supervision Station Conducts Special Supervision on Cold Test Release for Tianwan Nuclear Power Unit 8

The Cold Functional Test (hereinafter referred to as the cold test) is the first major comprehensive test for a nuclear power unit transitioning from the installation phase to the commissioning phase. It is a key core link to verify the pressure-bearing capacity and sealing performance of the nuclear island main system and equipment under design pressure conditions, and serves as a critical milestone to ensure the subsequent safe and stable operation of the unit. Recently, the Ministry of Ecology and Environment's North China Nuclear and Radiation Safety Supervision Station (hereinafter referred to as the North China Supervision Station) conducted comprehensive supervision on the cold test control point release for Tianwan Nuclear Power Plant Unit 8. Adhering to the principle of supervision moving forward, the station consolidated the pre-test foundation. Upholding the nuclear safety supervision philosophy of "prevention first, moving the checkpoint forward," the North China Supervision Station focused on the preconditions for the cold test control point release, verified various items pending rectification one by one, and ensured that all hidden dangers were effectively addressed, building a solid safety barrier for the smooth progress of subsequent tests.

Northwest Nuclear and Radiation Safety Supervision Station of the Ministry of Ecology and Environment Completes Routine Supervision and Emergency Assessment of Thorium-based Molten Salt Reactor

Recently, the Northwest Nuclear and Radiation Safety Supervision Station of the Ministry of Ecology and Environment (hereinafter referred to as the Northwest Supervision Station) organized a supervision team to conduct routine nuclear and radiation safety supervision and comprehensive emergency drill assessment for the 2 MW Liquid Fuel Thorium-based Molten Salt Experimental Reactor (hereinafter referred to as the Thorium-based Molten Salt Reactor) of the Shanghai Institute of Applied Physics, Chinese Academy of Sciences (hereinafter referred to as Shanghai Institute of Applied Physics). This supervision focused on the operational safety of the Thorium-based Molten Salt Reactor, effluent and environmental monitoring, radiation safety of nuclear technology utilization projects, and comprehensive emergency drills. The supervision team, through document review, on-site verification, and record tracing, primarily examined the effectiveness of the quality assurance program, personnel training and authorization, effluent and environmental monitoring records, emergency system documents, and the rectification records from previous inspections. At the same time, the supervision team observed the comprehensive emergency drill on-site and provided guidance based on actual conditions, conducting a full-process assessment of accident response procedures, cross-departmental coordination, and emergency response measures. In response to the issues and deficiencies identified during the supervision, the supervision team held a special communication meeting with the Shanghai Institute of Applied Physics and proposed rectification requirements.

Korea Atomic Energy Research Institute and SK Hynix to Jointly Use Proton Accelerator and Other Facilities for Semiconductor Radiation Reliability Research

The Korea Atomic Energy Research Institute announced on July 29 that its Proton Science Research Group has signed a mutual cooperation agreement with SK Hynix to jointly utilize research facilities such as the proton accelerator to advance research on semiconductor radiation reliability. According to the agreement, the two parties will conduct joint research on proton beams and neutron beams generated by the proton accelerator and the HANARO research reactor, and explore methods to simulate real atmospheric and cosmic radiation environments using high-energy proton beams, gamma-ray beams, and neutron beams for radiation impact assessment of semiconductors and other products. In outer space and high-altitude aircraft flight environments, the shielding effect of the atmosphere and magnetic field against cosmic radiation is relatively weakened. After being exposed to cosmic radiation, semiconductors may experience malfunctions or damage. Therefore, semiconductors used in mobile devices such as automobiles and satellites need to have their radiation resistance verified before being put into use.
