ARLA/CLUSTER: China instala antena para Ondas Longas (ELF) com 5x o tamanho de Nova York, mas alguns temem que possa ser um risco de difusão de cancro

China’s new antenna is five times the size of New York City, but some fear
it could be a cancer risk

China has built a giant experimental radio antenna on a piece of land
almost five times the size of New York City, according to researchers
involved in the highly controversial project.

The Wireless Electromagnetic Method (WEM) project took 13 years to build
but researchers said that it was finally ready to emit extremely low
frequency radio waves, also known as ELF waves. Those waves have been
linked to cancer by the World Health Organisation-affiliated International
Agency for Research on Cancer.

Although the project has civilian applications – officially it will be used
for earthquake and mineral detection and forms part of China’s 11th
five-year plan – it could also play a crucial role in military
communications.

Scientists said that its transmissions could be picked up by a submarine
lurking hundreds of metres under the sea, thus reducing the vessel’s risk
of having to resurface to receive transmissions.

The project follows the construction of China’s first military-grade Super
Low Frequency transmission station in 2009.

The next year, a Chinese nuclear submarine successfully communicated with
the station from deep water – making China the third country in the world
to have established such a submarine communication system, after the United
States and Russia.

But the Chinese navy is eager to expand its capacity and has been pouring
resources into the more advanced ELF (82Hz) radio technology, which allows
submarines to communicate with the command centre from a greater depth and
is harder to disrupt.

The Chinese government, however, has played down the importance of the
facility, which occupies some 3,700 sq km (1,400 square miles) of land, in
information released to the public.

Apart from the need to protect an important strategic asset, some
researchers said that the secrecy was to avoid causing public alarm
