Glenn T. Seaborg and his group, also at the University of California, Berkeley, discovered element 94 on February 23, 1941, and during the following year they named it plutonium, made enough for experiments, and established its fission characteristics. A gauge does not have enough radioactive material or the right kind of material to cause an explosion. The Tokyo Electric Power Company (TEPCO) has reported that seawater containing radioactive iodine-131 at 5 million times the legal limit has been detected near the plant. But scientists agree that the governments of Japan, the United States, and other nations on the Pacific Rim need to ramp up studies of how far this contamination might spread and in what concentrations.Given that the Fukushima nuclear power plant is on the ocean, and with leaks and runoff directly to the ocean, the impacts on the ocean will exceed those of Chernobyl, which was hundreds of miles from any sea, said Ken Buesseler, senior scientist in marine chemistry at the Woods Hole Oceanographic Institution in Massachusetts. A nuclear electromagnetic pulse (EMP) is the time-varying electromagnetic radiation resulting from a nuclear explosion. We have a few data points from the Japanese all close to the coast but to understand the full impact, including for fisheries, we need broader surveys and scientific study of the area.Buessler and other experts say this much is clear: Both short-lived radioactive elements, such as iodine-131, and longer-lived elements such as cesium-137, with a half-life of 30 years can be absorbed by phytoplankton, zooplankton, kelp, and other marine life and then be transmitted up the food chain, to fish, marine mammals, and humans. In general, you should avoid contact with radioactive sources except in controlled situations such as a doctor administering radioisotopes for medical diagnosis or treatment.
