SASAC re­futes ru­mors Chi­nese high-speed trains pose ra­di­a­tion safety risks

Global Times US Edition - - BIZUPDATE -

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.
