The world gymnastics championships will be hosted by Tokyo this October as originally planned, despite earlier concerns about high radiation levels following the March 11 earthquake and tsunami, the International Gymnastics Federation said Sunday.

The FIG found no scientific basis to call off the Oct. 7-16 event at Tokyo Metropolitan Gymnasium, which acts as the main qualifier for the 2012 London Olympics.

FIG president Bruno Grandi said the federation made the decision after consulting with experts who said it would be safe to go ahead as scheduled with the worlds.

"I am relieved. The FIG executive committee was not moved by sentiment and made a composed decision," said Japan Gymnastics Association president Hidenori Futagi.
