The Nuclear Safety and Security Commission said its land-based xenon detector in the northeastern part of the country found traces of xenon-133 isotope on nine occasions, while its mobile equipment off the country's east coast detected traces of the isotope four times.
But the NSSC said it had detected xenon-133, a radioactive isotope that does not occur naturally and which has in the past been linked to North Korea's nuclear tests.
The Korea Institute of Nuclear Safety said the level of xenon-133 isotopes found in the samples was similar to levels normally detected at its two radioactive gas detectors on the eastern and western coasts.
87) De Geer further concluded that the near-absence of another radioactive isotope "could only be explained by a significant [radioactive] xenon-133 contamination of the test site beforehand, e.
Over a seven-hour period, 7,780 curies of iodine-131 and 20,000 curies of xenon-133 were released.
The two are xenon-133 and xenon-135, and as their radioactivity is reduced to about half in about five days and nine hours, respectively, their existence suggests that a nuclear fission took place recently, according to Matsumoto.
amounts of xenon-133 and xenon-135 were found in gas samples from the No.
