SASAC refutes rumors Chinese high-speed trains pose radiation safety risks
Electromagnetic radiation on Chinese high-speed trains is within a safe range, said the State-owned Assets Supervision and Administration Commission (SASAC) on its official Wechat account on Sunday, refuting rumors that such radiation poses a health hazard.
“Such slander appeared on the internet in 2013, with highly similar content claiming that Chinese bullet trains have radiation safety concerns,” said the SASAC.
All electric appliances emit radiation. That includes mobile phones and razors, which are used in daily life. Radiation will not affect people within a safe range, said the SASAC.
The safety standard for electric field radiation is less than 5 kilovolts per meter, according to the International Commission on Non-ionizing Radiation Protection. The radiation level of Chinese bullet trains is within the range of 0.011-0.021 kilovolt/meter in high-speed railway cars, the connections of cars and the cabs of different models, according to data measured by the Beijing Bureau of China Rail, the SASAC said.
“The amount is far below the international standard, which is unlikely to harm human beings,” said the SASAC.
“The electromagnetic radiation mainly comes from the traction motor at the bottom of the carriage,” said Jiang li, an expert of China Railway Rolling Stock Corp (CRRC), the SASAC reported.
Jiang said that the metal shells of domestic carriages have a shielding effect, and the thickened metal plate under the seat can block radiation.
An anonymous source at CRRC Qingdao Sifang Rolling Stock Research Institute Corp confirmed the remarks.
“Your chemistry teacher will cry you a river,” commented the SASAC when responding to a rumor that France’s high-speed train, the TGV, uses lead sulfide as an isolation layer to reduce radiation.
