RA­DIO WAVES HELP TO RE­DUCE DELHI SMOG

Athletics Weekly - - Dip Finish -

LAST week­end’s Delhi Half-Marathon race used ul­tra-high fre­quency (UHF) ra­dio waves to clear the air for the 35,000 run­ners.

Or­gan­is­ers be­lieve the ex­per­i­men­tal tech­nique helped to im­prove the city’s no­to­ri­ous air qual­ity by about 30%.

The race also took place ear­lier this year to avoid the Di­wali fes­ti­val, held in Novem­ber, when the fire­crack­ers are set off.
