Japan urged to halt release of toxic water

Environmental and social experts from across Asia have called on Japan to refrain from contaminating the sea with radioactive wastewater after it began test running the equipment to discharge toxic water from a crippled nuclear power plant into the Pacific.

The nuclear-contaminated wastewater from the Fukushima Daiichi Nuclear Power Plant will contain traces of tritium, a radioactive isotope, and possibly other radioactive traces such as carbon-14, scientists said.

"Nobody wants to dump (radioactive substances) into the ocean," said David Krofcheck, senior lecturer in the faculty of science at the University of Auckland in New Zealand.
