A study conducted by CSULB two professors, and grad students
found radioactive kelp off the coast of Calif. after the devastating earthquake
in Japan damaged the nuclear reactors last year.

Professors Steven Manley, and Chris Lowe conducted the study
about a month after the nuclear waste was released into the atmosphere and the
seawater. Professor Manley said, “kelp is the ideal testing subject because the
canopy is not only affected by the water, but the radioactive material in the
air also lands on the top. Kelp is like a sponge for the material we were
looking for.”
The sample kelp was taken from seven different locations up
and down the coast places like, Corona Del Mar, Monterey Bay, Palos Verdes, an
several places in Orange County.
In Corona Del Mar the level of radioactivity was 250 times
higher that it should be, making it the highest radioactive material. Manly
said this could be due to a few things, the first is the weather pattern. If
the rain was heavier in the area when the radioactive material was in the
atmosphere, the next possibility is the run off from Huntington Beach, which
flushes all the material right into the canopies.
Graphic Art’s student, Tatiana Maldonado said ”I’d be
worried that the radioactivity could harm not only people but also the animals
in the ocean.” This concern, although valid, is unnecessary. The amount of
radioactivity was small, and only has a half life of eight days, which means it
was gone within a few weeks after the study.
More studies are being performed to see if any other radio
active material is present in the kelp.
