The Silent Killer, Radon


Radon is a colorless, odorless, and tasteless radioactive substance classified as a Group 1 carcinoge 

by the World Health Organization (WHO), known to cause lung cancer. Although invisible, 

it constantly threatens our lives from behind the scenes of our living spaces.


News“Ministry of National Defense has been indifferent for over 10 years”… Radon detected 5 times higher in underground bunker commanded by the president

It has been claimed that radon, a class 1 carcinogen, was detected at levels exceeding the recommended standard in the B-1 bunker located within the Army Capital Defense Command.

Radon is known to cause lung cancer and has been designated as a Group 1 carcinogen by the World Health Organization. The B-1 bunker is a place where joint ROK-US exercises are conducted in peacetime and is used as a command facility by the president and military leaders in wartime.

People Power Party lawmaker Yoo Yong-won held a press conference at the National Assembly on the 17th and disclosed the radon levels measured by the military in some areas of the B-1 bunker in 2020, 2022, and 2024.
