A study says that last year’s nuclear disaster and resulting radioactive leakage at the Fukushima nuclear power plant might cause one-thousand-300 cancer-related deaths around the world.

A research team at Stanford University in the U.S. studied the effects of radioactive substances through a 3D global meteorological model. The researchers found that the radioactive materials leaked from the Fukushima nuclear power plant may cause cancer in a maximum two-thousand-500 people. They said that of those people, up to one-thousand-300 may die.

The research team said that the effects caused by radioactive leakage are hugely different depending on weather conditions. It added that the damage wrought by the Fukushima nuclear accident was not worse on land, since 80 percent of the leaked radioactive substances flowed into the sea.
