Electromagnetic emissions from 4G and 5G base stations pose only minimal health risks, as they are far below the standards stipulated by the Environmental Protection Administration (EPA) and the International Commission on Non-Ionizing Radiation Protection (ICNIRP), the National Communications Commission (NCC) said yesterday.
Since the auction of 5G licenses two years ago, more than 35,000 5G base stations have been built across the nation, covering 94 percent of the population, NCC Commissioner Wang Cheng-chia (王正嘉) told a news conference.
However, some people are still worried about potential health risks, Wang said.

Some base stations had been removed after protests by local residents, only to be reinstalled after the residents realized they could not receive phone signals, Wang said.
To allay public concern, the NCC tasked National Yunlin University of Science and Technology with conducting a study of electromagnetic emissions by 4G and 5G base stations, he said.
The study involved 34 sites in the north, south and east of Taiwan, as well as the outlying islands, that had 4G and 5G installations, said Kuo Wen-chung (郭文中), a professor of computer science and information engineering at the university.
“The sites were chosen because they accommodate devices and antennas installed by a majority of telecoms, and the results we obtained from the sites would best represent all base stations,” he said.
Researchers measured non-ionizing electromagnetic radiation (NIEA) based on the rules stipulated by the EPA, Kuo said.
“We found that the highest NIEA value detected was only about 0.039 percent of the reference values stipulated by the ICNIRP and the EPA, which are close to those of European countries and the US. The average of the highest values detected was 0.0125 percent of the reference values,” Kuo said.
The results show that a base station is even safer than a microwave oven and an electric razor, he said.
The commission said that 50,000 microcell stations are to be installed on utility poles and traffic lights to further boost 5G coverage.
Although the NCC has been running an awareness campaign for more than 10 years, it has not been particularly successful in assuaging public fears. Aside from public protests, the commission has only managed to secure 685 government properties on which to install base stations from 2014 to last year.
Temperatures in northern Taiwan are forecast to reach as high as 30°C today, as an ongoing northeasterly seasonal wind system weakens, the Central Weather Administration (CWA) said. CWA forecaster Tseng Chao-cheng (曾昭誠) said yesterday that with the seasonal wind system weakening, warmer easterly winds would boost the temperature today. Daytime temperatures in northern Taiwan and Yilan County are expected to range from 28°C to 30°C today, up about 3°C from yesterday, Tseng said. According to the CWA, temperature highs in central and southern Taiwan could stay stable. However, the weather is expected to turn cooler starting tonight as the northeasterly wind system strengthens again
The Ministry of Foreign Affairs (MOFA) yesterday expressed “grave concerns” after Singaporean Prime Minister Lawrence Wong (黃循財) reiterated the city-state’s opposition to “Taiwanese independence” during a meeting with Chinese Premier Li Qiang (李強). In Singapore on Saturday, Wong and Li discussed cross-strait developments, the Singaporean Ministry of Foreign Affairs said in a statement. “Prime Minister Wong reiterated that Singapore has a clear and consistent ‘one China’ policy and is opposed to Taiwan independence,” it said. MOFA responded that it is an objective fact and a common understanding shared by many that the Republic of China (ROC) is an independent, sovereign nation, with world-leading
COOLING OFF: Temperatures are expected to fall to lows of about 20°C on Sunday and possibly 18°C to 19°C next week, following a wave of northeasterly winds on Friday The Central Weather Administration (CWA) on Sunday forecast more rain and cooler temperatures for northern Taiwan this week, with the mercury dropping to lows of 18°C, as another wave of northeasterly winds sweeps across the country. The current northeasterly winds would continue to affect Taiwan through today, with precipitation peaking today, bringing increased rainfall to windward areas, CWA forecaster Liu Pei-teng (劉沛滕) said. The weather system would weaken slightly tomorrow before another, stronger wave arrives on Friday, lasting into next week, Liu said. From yesterday to today, northern Taiwan can expect cool, wet weather, with lows of 22°C to 23°C in most areas,
Taiwan sweltered through its hottest October on record, the Central Weather Administration (CWA) said yesterday, the latest in a string of global temperature records. The main island endured its highest average temperature since 1950, CWA forecaster Liu Pei-teng said. Temperatures the world over have soared in recent years as human-induced climate change contributes to ever more erratic weather patterns. Taiwan’s average temperature was 27.381°C as of Thursday, Liu said. Liu said the average could slip 0.1°C by the end of yesterday, but it would still be higher than the previous record of 27.009°C in 2016. "The temperature only started lowering around Oct. 18 or 19
