Nuclear Fallout Part II: the health consequences of Pyongyang's nuclear program


Pollution and health risks exists at every point along the nuclear weapons’ development chain, from the initial mining and milling operations to the enrichment process, and finally from testing nuclear devices. In this two-part article I will examine each of those areas and the health risks associated with them.

In this second part, I finish discussing the health consequences of North Korea’s nuclear program by examining issues related to their underground testing. (Part I can be read here.)

Testing


After producing the needed nuclear fuel and solving the other matters associated with creating a nuclear device, the next step is testing.

After decades of work the regime was able to test its first nuclear device in 2006. The underground test was carried out within Mount Mantap at the Punggye-ri nuclear test site. However, there is no such thing as a safe nuclear test, even when they’re underground. The original tunnel for the 2006 test was closed up shortly after the test as a result of radiation releases according to 38 North. Since 2006, five additional tests have been carried out in different tunnels. Further reporting indicates that another delayed leak was also detected as a result of post-tunneling activities in 2013.

Even under the best circumstances, underground nuclear testing still can release some radionuclides into the atmosphere. Less than optimal testing can pose a much greater radiation risk to those downwind of the test site. Initial radiation releases from a containment failure occur through “venting” but releases can continue for longer through “seeps”, where radiation finds its way out of the underground site through small fissures and openings in the overlying rock. Radioisotopes of xenon (such as 133Xe and 135Xe) are almost impossible to contain and can travel across the globe, as Canadian detectors picked them up after the very low-yield 2006 test.


Punggye-ri is in a mountainous area with little population but the main tunnel entrances are less than 2 miles away from the boundary of the Hwasong Concentration Camp. Due to the extreme human rights violations facing prisoners, we can’t hear their stories or send professionals over to determine how much radiation they have been exposed to. Residents within the larger area, however, have been able get their experiences to the broader world.

In 2017, South Korea reported that four defectors who lived in the area around Punggye-ri showed signs of radiation exposure. Defector Lee Jeong Hwa, who lived in Kilju County, said, "So many people died we began calling it 'ghost disease’…We thought we were dying because we were poor and we ate badly. Now we know it was the radiation." Unfortunately, the inability to do detailed testing on people still living in the area and gather more definitive evidence prevents us from knowing the full effects of the testing.

Negative health impacts from underground nuclear testing is easily supported by looking at the results of underground testing in the United States. According to the US National Cancer Institute, some 2,800 annual cases of thyroid cancer within the US can be attributed to the “underground era” of 1962-1992, when the United States (and the Soviet Union) was limited to testing nuclear devices underground by treaty. While North Korea has only had a limited number of tests, those tests have increased radiation levels for the region and caused an unknown level of damage to the population. Of particular concern are the 20,000 Hwasong prisoners, who are also suspected of being used as slave labor to help dig the tunnels used at Punggye-ri.

The stability of portions of Mount Mantap is also of concern after six tests, and surface changes as a result of ground shifting have been studied in detail. The first two (of four) tunnels are likely to be unusable for any future testing. Worries over accidental radiation releases from collapsing tunnels spurred China to install additional radiation detectors along their border with North Korea in 2017 and at a newly constructed border crossing in 2019.
The other two tunnels exist to the west and south and have not been used to-date. Their entrances were demolished in May 2018; however, questions remain about the irreversibility of those closures.

Occasional rumors of a possible future above-ground test (for which there are very few potential testing sites) raises the stakes even more. Radiation would flood over Japan and would reverse decades of atmospheric radionuclide decline around the globe.

Conclusion

The known risks associated with the chemicals and processes involved in mining, milling, and enriching uranium, as well as in the production of other radioactive materials, supports the descriptions of illnesses as told by unrelated sources, each with first-hand knowledge of the locations discussed.

Despite the guarantees of the North Korean constitution and international law regarding the right to favorable working conditions and the right to pick one’s career (or to leave it), expert and defector testimonies, coupled with satellite imagery, paints a very different and dangerous story. It can be said that a major humanitarian and health crisis is brewing within North Korea as we know the substandard state of their nuclear program – not just in terms of technology but also safety.

Most of the facilities within Punggye-ri’s 17-kilometer-long compound still stand, waiting to be used again. Yongbyon continues to grow and thousands of additional scientists, laborers, and their families have been moved in under Kim Jong Un. The mines and milling plants still produce materials to be sent to enrichment facilities. And the regime keeps working on their abilities to deliver ballistic missiles to any part of the globe. It is clear that the sixty years of nuclear harm now affecting the tens of thousands of North Koreans who have worked to develop Pyongyang’s nuclear program over three generations of Kim will continue into the future, causing more harm, more sickness, and will likely require the efforts of multiple countries to finally resolve once the Kim Era is over.

NoKo's Underground Nuclear Nightmare

UPDATE: On October 31, 2017, Japanese media are reporting that a large tunnel collapse occurred at the site, killing around 200 people. This has yet to be confirmed.


On September 3, 2017, North Korea conducted its sixth and largest (by far) nuclear test. North Korea's only nuclear test site is Punggye-ri in North Hamgyong Province. At this point I want to say that this post is speculative in nature and that there is little concrete evidence to support what I am suggesting. However, there is anecdotal evidence and a logic to it. Enough so that I feel this is worth discussing.

The main tunnel at Punggyi-ri also happens to be less than 2 miles away from the boundaries of the Hwasong concentration camp (Kwan-li-so 16).


The apparent location (based on USGS information) of this most recent nuclear test lies a mere 0.3 miles (0.5 km) away from the camp fence, and North Korea's first test in 2006 appeared to have taken place inside the camp itself (underground, of course).


I believe the proximity of Punggye-ri and Camp 16 (with its 20,000 prisoners)  may be important.

There are multiple reports by defectors (including testimony by Ahn Myong-chol, a former guard at Camp 22), that North Korea has a history of using prisoners in medical experiments, including testing chemical weapons, as well as prison labor for the construction of sensitive military facilities, including underground sites.

Based on the relative locations[n1] of each of the nuclear tests, the underground tunnel system is massive, with the majority of test sites more than 3 miles away from the main tunnel entrance. The Sept. 3, 2017 test is almost 5 miles away! This means lots and lots of tunneling work.

A few small mounds of debris can be seen at the entrances of the various tunnel entrances; however, the amount of debris is nowhere near enough as would be required for excavating a tunnel a mile long, let alone multiple tunnels. A very basic tunnel 1 mile long, six feet tall, and six feet wide would create 190,080 cubic feet of material. However, an image released by North Korean TV suggests their tunnels aren't simply a straight line (which could easily become disastrous during testing).



This suggests that the North Koreans are using material from new tunnels to back fill the old tunnels after each nuclear test, as the growth of the outside debris mounds do not entirely reflect the growth that would be needed if they were dumping all of the excavated materials outside. The fact radioisotopes can be detected outside of the country after some tests, shows that their testing site is far from sealed, thus it would be necessary to mitigate the slow continual release of radiation by filling up used tunnels with the material taken to construct new ones. Unfortunately, the discovery of visible changes to the surface of the mountain raises the likelihood that further releases of radiation will happen.


Back to Hwasong, it's not beyond the realm of possibility that the regime is taking advantage of this nearby and captive workforce to do the difficult and dangerous task of constructing these testing tunnels. There is a fair amount of evidence that prisoners are used to construct the thousands of tunnels and underground facilities that have turned much of North Korea's ground into Swiss cheese. And, there are even occasional but brief comments that can be found in media sources that touch on the idea of these prisoners being used to do the hard work at Punggye-ri.

Average citizens are subjected to terrible conditions in the country's coal mines, and even in uranium mines and enrichment facilities safety is practically nonexistent, with workers developing multiple radiation-related illnesses. Political prisoners on the other hand aren't even considered citizens. Their very title of "human" appears to vanish along with every right and privilege that otherwise exists in North Korea.

Using these men to dig, repair, and fill the tunnels has several benefits to the regime. Here are four benefits that immediately come to mind:

1) The government doesn't have to worry about paying wages or properly feeding them, saving large sums of money.
2) There are no families to deal with whenever a loved one comes home with a shattered leg or dying from radiation exposure (or coming home in a body bag).
3) Due to the way such prisoners are managed, using them provides a large level of greater secrecy and security. Even loyal soldiers may inadvertently spill sensitive information to friends or family. Who are slave laborers living behind electrified fences going to tell?
4) Using expendable lives saves the lives of more valuable people.

We do know that the tunneling process itself is fairly basic. North Korea doesn't have the ability to employ the large modern mining or tunneling equipment other industrial countries have. Using dynamite, hand tools, brute force, and small carts to carry away rocks is about all they have. Satellite imagery confirms this is true at Punggye-ri, too, as the simple equipment can clearly be identified.

Beyond the horrors associated with working hour after hour and week after week near incredibly toxic mixes of radiation and heavy metals, there are also dangers faced by nearby populations.

The northern part of Korea has always been neglected. This was the case during the historic dynastic period and was the case during North Korea's famine - when supplies were cut off and redirected to the more "important" capital region. Punggye-ri is located in the northernmost province. Of North Hamgyong's 2.5 million inhabitants, nearly 2 million lie directly east and north of the nuclear site, which means any radiation release will spread to those areas on wind currents.

Absent full-on containment failure, where plumes of material is tossed into the atmosphere, partial failures can still release Cesium-137, Iodine-131, and Strontium-90, all of which can spread by the wind and contaminate the ground (and thus the grass, which in turn will contaminate any animals eating that grass and eventually the people eating the animals). Seepage of Krypton-85 and Xenon-133 through cracks in the mountain can also contaminate the area. Krypton-85 has a half-life of 10.7 years, meaning if any was released by the first nuclear test back in 2006, half of it is still hanging around. To add context and bring this closer to home, the National Cancer Institute published a study in 1997 that showed 2,800 cases of thyroid cancer in the US each year can be attributed to our own nuclear tests during the "underground era" (1962-92).

Continuing research by 38 North suggests that major fractures may have developed in the mountain, and that further large-yield nuclear tests could severely destabilize the site and release enormous amounts of radioactive debris.

We may never know for certain if prison labor was used to build these miles of tunnels and what, if any, effects have happened as a result of radiation contamination, but the fact there's enough anecdotal evidence and internal logic to support the basis of this post is very disturbing. The world already knows about the routine torture, rape, murder, forced abortions, and starvation that goes on in North Korea's prison camps. The world knows about the lasting harm to people living in the US and on small Pacific islands near nuclear testing sites. I don't see what's so difficult about expecting that the two scenarios would merge in North Korea when all of the pieces are laying in front of us.
