Notwithstanding the artificial sources of radiation discussed in this video, the elevated natural levels of radiation are likely due to higher levels of cosmic radiation, rather than ultraviolet (UV) radiation, owing to the thinner atmosphere at high altitude. Moreover, natural levels vary widely owing to local geology; however, I do not know the specific situation in Tibet.
Concerning the dirty bomb hypothesis presented in this video, it is an interesting idea, but its validity seems dubious, since any territory that is the target of such weapons will be rendered uninhabitable for centuries; thus, is not a good strategy for conquest or annexation. Storage and delivery of such weapons is also problematic, for obvious reasons.

@jmc129 No, this is not censorship because censorship means that the videos would be removed, which is not happening. The videos are simply not being promoted, presumably because they do not make money for YouTube, and nothing more sinister than that. The same is equally true for the many brilliant videos by very talented creators on mathematics, physics, computer science, and so on. Hardly anybody watches them. Lei's Real Talk is an outstanding channel and has improved greatly from when it started, so I think its numbers of views, subscribers, and likes will grow. YouTube does at least host these video free of charge for creators and viewers. The cost of all that computer and network equipment is enormous.

@drumpfdon760 No, although there was some interbreeding, Neanderthals only contributes about 1-4% to the DNA of modern humans throughout Eurasia, including East Asians, and possibly confers some strengths such a resistance to certain diseases, as well as the cause of some diseases. There was also a closely related sub-species called Denisovan found in Siberia and Tibet, who were related to Neanderthals. Some of their DNA ended up in the aboriginal people of Australia, Oceania, Polynesia, etc. but not mainland east Asia. So, DUMPF Don, unless you are an African, you can take pride in the knowledge that you are likely about 3% archaic hominid. We are all the same.
