Japan Discovers Plutonium Far From Crippled Reactor .

Trace amounts of plutonium were found as far as 28 miles from the damaged Fukushima Daiichi nuclear-power plant, the first time that the dangerous element released from the accident was found outside of the immediate area of the plant.

The government also reported a rare detection of strontium, another highly dangerous element, far from the crippled reactor, in one spot as far away as 50 miles. Most of the radioactive material discovered to date in the communities surrounding Fukushima Daiichi has been cesium or iodine.

Plutonium had previously been detected in Japan after atmospheric nuclear tests, sometimes at higher levels than were found from the June-July samples, a science ministry official said. However, the ministry cites higher-than-usual level of Plutonium-238 found in the soil samples from the six locations as evidence that plutonium release was not limited to the plant's compound.

Strontium-89 and -90 were also found in almost half of the 100 samples, in one case as far as the edge of the 50-mile zone registering measurement of 500 becquerels per square meter of Strontium-89 and 130 becquerels of Strontium-90.
