Summary and Discussion
Recently, Japan has undergone one of the most tragic and expensive natural accidents in history. It experienced a 9.0 earthquake, which struck some nuclear power plants. Many of these power plants experienced a meltdown and have released much waste, including the deadly radioactive isotope called strontium-90. Strontium-90 has a similar size to calcium, making it difficult to separate the two. This is where the algae, Closterium Moniliferum, comes into play. This algae has a "unique penchant for sequestering strontium into crystals". Generally, C. Moniliferum, tries to go after barium. However, stronium-90 has a size in between calcium and barium, so the algae vacuums this isotope too. One benefit to this algae is that it does not convert the harmless calcium. In addition, the conversion factor could be speeded up by seeding barium in the nuclear power plant's site.
This find could be crucial to helping Japan in its effort to clean up this disaster by saving money and time. The algae is effective in both of these categories. It is cheap to culture and can start precipitating strontium-90 crystals in half an hour. This ingenious solution to the nuclear crisis is an excellent example of how science can be applied to problems in real life. The algae is an excellent find by scientists and will provide tremendous help for the people of Japan.

Good blog. I find it interesting that algae can actually try to help take some of the radioactive material out of the environment. I did my blog on how some water around Japan became radioactive after the disaster. My article said it is hard to filter radioactive materials out of water. If algae can filter out the radioactivity so easily, that is a much easier way to clean up the radioactive materials. Overall, good blog.
ReplyDeleteNice read! Good references!
ReplyDeleteIts a very hopeful article under the dark nuclear-holocaust sky. The occurrence of radio-isotopes in water is a clear and 'real' threat and has the potential to affect millions.
I too wrote about it here on my blog, where I discuss recent scientific curiosities.
