Seoul detects radioactive gas from N. Korea nuke test

A radioactive gas, xenon-133, has been detected from the recent North Korean nuclear test, the South’s nuclear watchdog said, adding that it is still unclear whether it was from a hydrogen bomb test as Pyongyang claimed.

Traces of the xenon isotope were detected in the north-eastern part of the country on nine occasions, the South Korean Nuclear Safety and Security Commission said. The Commission’s mobile detectors also found traces of xenon off the country's east coast four times.

“It was difficult to find out how powerful the nuclear test was with the amount of xenon detected, but we can say the xenon was from North Korea,” executive commissioner Choi Jongbae told a news conference in Seoul on Wednesday.

Earlier in September Pyongyang claimed that it had successfully tested a hydrogen bomb which can be mounted on an Intercontinental Ballistic Missile (ICBM).

Seoul started collecting radioactive nuclides and increased its radiation monitoring level following Pyongyang’s nuclear test, according to numerous reports from the Nuclear Safety and Security Commission.

Xenon was first detected in the sample collected by “the stationery capturing equipment installed on land”, the commission’s report said September 8. However, at that time it wasn’t clear whether the xenon level was linked to the North’s test.

The amount of the radioactive gas detected is some 0.43 milibecquerel per cubic meter, the commission said, as cited by Yonhap news agency.

This amount would not have any effects on public health as South Korea's radiation levels remain normal, the commission added.

Xenon, a colorless and odorless gas, occurs naturally and can be found in mineral springs, asteroids and the Earth’s atmosphere. It is often used in the manufacture of lighting. However, its isotope xenon-133 does not occur naturally. Small amounts of it is used in medicine for diagnostic inhalation only, according to medical websites.

Exposure can cause nausea, convulsions and a potentially fatal coma, according to the Lantheus medical website. It has been known to cause cancer and adverse reproductive effects.

The test aggravated the already tense situation on the Korean peninsula even further. In response to North Korea’s actions, South Korea and the US began discussions on the deployment of an aircraft carrier and strategic bombers in the region.

自衛隊も上空の大気やチリを採集しました。その結果は特段のことはなかったのでは?

韓国がキセノン133を検出としていますが、キセノンは稼働中の原発からも放出されています。特に韓国の原発は放射性物質の漏れが多いとの説もあります。韓国は甲状腺がん発生率が世界でトップだったことも。

北朝鮮が水爆実験をやったと言っている訳ですからキセノンなどが検出されても当然。検出されてもその量は、原発から放出される分と比較すれば、極少なかったと言うことでしょう。

管理人は、韓国の原発が稼動していることのほうが環境への放射性物質の放出がよほど多いのではないかと皮肉な見方をせざるを得ません。

韓国には、米軍に核兵器の再配備を要請する声もあります。
