The National Atomic Research Institute (NARI) is preparing to install a 70 million electron volts (MeV) cyclotron to produce short-half-life radiopharmaceuticals, which would stabilize the domestic supply of medical isotopes.
The machine is scheduled to be completed in 2026 and begin producing radiopharmaceuticals in 2027, the institute said yesterday.
Taiwan has to import most of its short-half-life radiopharmaceuticals from other countries, NARI vice president Wang Jeng-jong (王正忠) said.

As radiopharmaceuticals cannot be stored in large amounts due to their short half-life, the country experienced a shortage of the drugs during the COVID-19 pandemic, Wang said.
The institute could in the past few years only rely on a 30Mev cyclotron it owns to produce thallium chloride (thallium-201) injection, gallium citrate (gallium-67) injection and other medical isotopes that are used for imaging to diagnose heart diseases or malignant tumors, Chang said.
However, the 30MeV cyclotron has been in use for more than 30 years, and the institute is preparing to build the newer, larger 70MeV cyclotron, he said.
The two cyclotrons could ensure the continual supply of radiopharmaceuticals, as one could serve as a backup if the other one malfunctioned, he said.
Radiopharmaceuticals produced in Taiwan are mainly used for the diagnosis of illnesses, Chang said.
“The energy range for the new cyclotron would be between 28MeV and 70MeV, which enables it to produce radiopharmaceuticals that are unable to be produced by the 30 MeV cyclotron, such as Actinium-225, which is often used in cancer treatment,” he said.
Aside from producing radiopharmaceuticals, the new cyclotron could be used to develop advanced materials and test radiation resistance of space components and semiconductors, Chang said.
“In the future, chip manufacturers can have radiation-resistance testing done in Taiwan, rather than overseas,” he said.
LOUD AND PROUD Taiwan might have taken a drubbing against Australia and Japan, but you might not know it from the enthusiasm and numbers of the fans Taiwan might not be expected to win the World Baseball Classic (WBC) but their fans are making their presence felt in Tokyo, with tens of thousands decked out in the team’s blue, blowing horns and singing songs. Taiwanese fans have packed out the Tokyo Dome for all three of their games so far and even threatened to drown out home team supporters when their team played Japan on Friday. They blew trumpets, chanted for their favorite players and had their own cheerleading squad who dance on a stage during the game. The team struggled to match that exuberance on the field, with
Taiwanese paleontologists have discovered fossil evidence that pythons up to 4m long inhabited Taiwan during the Pleistocene epoch, reporting their findings in the international scientific journal Historical Biology. National Taiwan University (NTU) Institute of Ecology and Evolutionary Biology associate professor Tsai Cheng-hsiu (蔡政修) led the team that discovered the largest snake fossil ever found in Taiwan. The single trunk vertebra was discovered in Tainan at the Chiting Formation, dated to between 400,000 and 800,000 years ago in the Middle Pleistocene, the paper said. The area also produced Taiwan’s first avian fossil, as well as crocodile, mammoth, saber-toothed cat and rhinoceros fossils, it said. Discoveries

Whether Japan would help defend Taiwan in case of a cross-strait conflict would depend on the US and the extent to which Japan would be allowed to act under the US-Japan Security Treaty, former Japanese minister of defense Satoshi Morimoto said. As China has not given up on the idea of invading Taiwan by force, to what extent Japan could support US military action would hinge on Washington’s intention and its negotiation with Tokyo, Morimoto said in an interview with the Liberty Times (sister paper of the Taipei Times) yesterday. There has to be sufficient mutual recognition of how Japan could provide
