China has built a massive experimental radio antenna that can communicate with submarines in deep water, but some are worried about potential health risks, reports the South China Morning Post. The Method project was built at a site nearly five times as big as New York City is, and is now ready to broadcast extremely low frequency radio waves, the newspaper reports. The project is officially used for earthquake and mineral surveys but could also play a crucial role in military communications by allowing deep-sea submarines to record without having to show up.
The newspaper reports that China first completed a military ̵
Concerns about the possible negative effects of extremely low health frequency (or ELF) waves have been documented by the World Health Organization. The organization noted that short-term exposure to high-level ELF magnetic fields can lead to nerve and muscle stimulation and central nervous system changes, and recommended the development of international exposure guidelines. The WHO also reviewed studies on possible associations with childhood leukemia resulting from long-term exposure to ELF magnetic fields. Although it was not clearly linked, it recommended further studies and suggested that governments and industries should look for cost-effective ways to reduce exposure when developing new facilities and equipment.
According to the South China Morning Post revealed a calculation of the Chinese Navy A person standing at the emission site would be exposed to radiation of not more than 10 watts, enough to run multiple LED light bulbs. The marine researcher at Wuhan, a marine researcher, found that these values were far too low for a risk. However, the newspaper cites a nameless Beijing-based researcher who said the Ministry of Ecology and the Environment called for a comprehensive review of the project's environmental impact, which was rejected.
A researcher at the Institute of Earthquake Forecasting, who was briefed on the project but was not directly involved, told the authorities that the authorities had recently completed the final inspection of the emissions site and found that it was operational.
