![]() This mechanism prevented major loss of uranium and fission products from the natural nuclear reactors for 1.2 b.y. The bitumen soon became a solid, consisting of polycyclic aromatic hydrocarbons and an intimate mixture of cryptocrystalline graphite, which enclosed and immobilized uraninite and the fission-generated isotopes entrapped in uraninite. Of course the pro nuclear side provided no hints that these isotopes were not generated by civilian nuclear plants but specialized medical nuclear reactors. ![]() Liquid bitumen was generated from organic matter by hydrothermal reactions during nuclear criticality. Organic matter helped to concentrate quantities of uranium sufficient to initiate the nuclear chain reactions. These organic-rich reactors may serve as time- tested analogues for anthropogenic nuclear-waste containment strategies. Reactors 7 to 9 are the subjects of this study. Disposal means burying it in the center of a large lump of concrete and then burying that.Of the sixteen known Oklo and the Bangombé natural fission reactors (hydro-thermally altered clastic sedimentary rocks that contain abundant uraninite and authigenic clay minerals), reactors 1 to 6 at Oklo contain only traces of organic matter, but the others are rich in organic substances. You'd basically have to call the appropriate government department, or a professional, to arrange for pickup and safe disposal. The theory is that this new molten-salt technology will be safer and greener. Once received into your possession it's illegal and unethical to destroy, throw away, reship, or basically do anything with the radioactive material. China is poised to test a thorium-powered nuclear reactor in September, the world’s first since 1969. You're essentially shipping around a weapon, and as they say "ignorance is no excuse" in the law. Shipping somebody a potentially harmful radioactive material without is would be comparable to shipping somebody a poison, which is a criminal offense. Around half of the packages I've received containing radium are over this legal threshold and so were sent illegally at a danger to everyone who came in contact with the box. The deteriorating radium lume is essentially a loose radioactive dust emitter and is illegal to ship even under this threshold. Black stainless steel watch featuring unidirectional bezel, Never Dark illumination system for visibility, and link. But this is for packages clearly marked as radioactive and containing some stable kind of radioactive material in an appropriate container. Each country has a figure for the amount of radiation on the outside of the box, etc. It's also illegal to ship radium in almost every case. But once it's entered your body you're being exposed to it continuously, at 0 distance (because its inside you) for decades. Hence why spending a few minutes or hours with a radium watch is theoretically not that harmful. The two main factors affecting the amount of radiation you receive are the distance between you and the radioactive material, and the length of time of exposure. So just breathing near a radium watch is dangerous. Even a light touch on the lume will transfer radium dust onto your hand, which can easily end up in your body one way or another. As it deteriorates that paint is releasing tiny particles of radium into the air, which can then be inhaled. Radium lume is extremely dangerous not because of how radioactive it is, but because the non-radium part of the paint is very old and is deteriorating. I've been told jokingly by numerous watchmakers and sellers that as long as I don't eat the paint, it's not dangerous. My watch with radium lume was setting off the compartment radiation counter. He died at 93.no indication of radium sickness. Anecdotally, my Dad worked on radium watches every day for 30 years. ![]() After my thorough research, I concluded that it is of no concern. I did a lot of research of the safety of this and how to handle it, and what I found has left me quite concerned about the lack of information and blaisé attitude many watchmakers and collectors have to this.įirstly, radium is not that radioactive. The sun like any other star is a fusion reactor, making atoms including the. I posted an article and some graphics about watches and radium somewhere on this forum. ![]() All watches with glow-in-the-dark lume on the dial and/or hands, usually identifiable on photos as a rough white paint, manufactured before the 60s, contain radium. Frequently, I receive watches containing radium-226, almost always without any mention of this from the seller. I've been amassing old watch parts as part of my journey to create custom watches from scrapped parts. ![]()
