In the aftermath of the tsunami, Japan saw itself dealing with a grave situation: a leaky nuclear reactor. But, the utility that owns the damaged Japanese facility has made an important announcement. The radioactive material that was seeping into the Pacific Ocean has now stopped.
1,500 litres of 'water glass' or sodium silicate were used to control and eventually stop the leakage on Wednesday.
Even though the leak has been stopped, major damage has already been done. Radiation of more than 7.5 million times the legal limit for seawater has been found on the tsunami-stricken coast.
Environmentalists are highly concerned at the seriousness of the situation.
The United States has sent a team of chemical-biological experts to Japan to help clear out nuclear waste materials.
