Institutions that use high-risk radioactive materials in Taiwan are subject to monthly inventory checks regarding safe handling and storage, an Atomic Energy Council (AEC) official said yesterday.
The official’s remarks came after the AEC on Wednesday issued a statement to reassure the public that Taiwan has a sound framework to regulate high-risk radioactive sources, following media reports that “dirty bombs” could be used in the Russia-Ukraine war.
Dirty bombs use conventional explosives that scatter radioactive material. While they do not have the destructive power of nuclear weapons, they could cause radioactive contamination.
A total of 83 hospitals, businesses and academic institutions nationwide use the radioactive isotopes cobalt-60, caesium-137 and iridium-192 for processes such as treating bacterial or fungal infections, Gamma Knife radiosurgery and the irradiation of blood, as well as welding and calibration, AEC Department of Radiation Protection Deputy Director Tsai Chin-hsien (蔡親賢) said.
The materials could pose a risk to human health if not managed safely, Tsai said.
The AEC uses a cloud inventory management system to track the materials on a monthly basis, Tsai said.
AEC personnel also conduct random inspections at the institutions to ensure that the materials are stored safely and securely, he said.
Taiwan also imports uranium-235 to generate electricity in its nuclear power plants, Tsai said.
According to Taiwan’s regulations, entities that want to import radioactive materials must present an import license obtained from the AEC to the customs office before the shipment can be cleared, he said.
The regulations also apply to the transportation and storage of radioactive materials to protect against the potential loss or theft of the substances, he added.
The materials must be stored in a secure manner, for example in a storage space with alarms and double doors to prevent break-ins, he added.
Russia on Monday repeated its claim that Ukraine was preparing to detonate a dirty bomb on its own territory, The Associated Press reported.
Ukraine, the US, the UK and France have rejected the claim.
Kyiv said Moscow was trying to divert attention from its own alleged plans to detonate a dirty bomb.
In 2011, following the loss of a shipment of iridium-192 during transportation, the AEC introduced rules regarding the movement of radioactive materials in Taiwan, such as requiring transporters to install a device on their vehicles to alert the driver in the event of any problems with the cargo, Tsai said.
The material was found intact at a metal recycling site 10 days later.
A group of Taiwanese-American and Tibetan-American students at Harvard University on Saturday disrupted Chinese Ambassador to the US Xie Feng’s (謝鋒) speech at the school, accusing him of being responsible for numerous human rights violations. Four students — two Taiwanese Americans and two from Tibet — held up banners inside a conference hall where Xie was delivering a speech at the opening ceremony of the Harvard Kennedy School China Conference 2024. In a video clip provided by the Coalition of Students Resisting the CCP (Chinese Communist Party), Taiwanese-American Cosette Wu (吳亭樺) and Tibetan-American Tsering Yangchen are seen holding banners that together read:
UNAWARE: Many people sit for long hours every day and eat unhealthy foods, putting them at greater risk of developing one of the ‘three highs,’ an expert said More than 30 percent of adults aged 40 or older who underwent a government-funded health exam were unaware they had at least one of the “three highs” — high blood pressure, high blood lipids or high blood sugar, the Health Promotion Administration (HPA) said yesterday. Among adults aged 40 or older who said they did not have any of the “three highs” before taking the health exam, more than 30 percent were found to have at least one of them, Adult Preventive Health Examination Service data from 2022 showed. People with long-term medical conditions such as hypertension or diabetes usually do not
POLICE INVESTIGATING: A man said he quit his job as a nurse at Taipei Tzu Chi Hospital as he had been ‘disgusted’ by the behavior of his colleagues A man yesterday morning wrote online that he had witnessed nurses taking photographs and touching anesthetized patients inappropriately in Taipei Tzu Chi Hospital’s operating theaters. The man surnamed Huang (黃) wrote on the Professional Technology Temple bulletin board that during his six-month stint as a nurse at the hospital, he had seen nurses taking pictures of patients, including of their private parts, after they were anesthetized. Some nurses had also touched patients inappropriately and children were among those photographed, he said. Huang said this “disgusted” him “so much” that “he felt the need to reveal these unethical acts in the operating theater
Heat advisories were in effect for nine administrative regions yesterday afternoon as warm southwesterly winds pushed temperatures above 38°C in parts of southern Taiwan, the Central Weather Administration (CWA) said. As of 3:30pm yesterday, Tainan’s Yujing District (玉井) had recorded the day’s highest temperature of 39.7°C, though the measurement will not be included in Taiwan’s official heat records since Yujing is an automatic rather than manually operated weather station, the CWA said. Highs recorded in other areas were 38.7°C in Kaohsiung’s Neimen District (內門), 38.2°C in Chiayi City and 38.1°C in Pingtung’s Sandimen Township (三地門), CWA data showed. The spell of scorching
