, an isotope of particular value for identifying nuclear
The researchers placed a cloud of xenon-133
atoms inside a magnetic trap and then jolted it with oscillating electric and magnetic fields.
Carrigan calculates that under the same weather conditions, a team monitoring a nuclear blast would have detected radioactive xenon-133
after 50 days and the lighter argon-37 after 80 days.
Because the half life of xenon-133
is 5.25 days and that of xeon-135 is 9.14 hours, criticality is very likely to have occurred just before the gases were analyzed.
in the northeastern part of South Korea.
South Korea's Nuclear Safety Information Center said Monday that trace amounts of radioactive xenon-133
had been detected at a detection station in Gangwon Province in the northeastern part of the country.
In South Korea, a small amount of radioactive xenon-133
has been detected
The report said extremely small amounts of iodine-131 and xenon-133
, both of which are not usually found in Nevada, were detected at a monitoring station near the Atomic Testing Museum in the city following a series of radiation leaks at the Fukushima Daiichi plant.
A very small amount of the radioactive substance xenon-133
was detected in California on Friday and its origin is believed to be the crippled Fukushima Daiichi nuclear power plant in northeastern Japan, U.S.
