Almost two months have passed since the nuclear crisis erupted at the nuclear power plant in Fukushima, Japan and some details of the damage are just emerging.
Japan's Asahi Shimbun reported on Monday that radioactive strontium-90 has been detected in the sea near the No. 5 and No. 6 reactors at the stricken nuclear complex.
That isotope in particular is known to be more dangerous than other radioactive materials, such as iodine-131 and cesium-137, and can be easily absorbed into the human body causing leukemia and various cancers.
This is the first time strontium-90 was detected in the sea and it was at 1.3 times the normal level.
