.> Uranium begins in the ground and ultimately is disposed of there. Here are the details of its life cycle:

.> Out Of The Ground: When in the earth, Natural Uranium is slightly radioactive, containing 0.7% U235, which is fissile, meaning scientists can split its atoms and use its energy for other purposes, and the 99.3% remaining is non-fissile U238. Uranium is mined or physically extracted from underground rocks by pumping toxic acids into the earth. Once the U235 is enriched to between 6% and 19%, it is used to power atomic reactors. Unfortunately, enriching atomic fuel also creates lots of extra depleted U238, which is desired for explosive munitions that start a fire that cannot be put out.

.> Into The Ground: Once used in a nuclear reactor or munitions, the used [called spent] uranium is highly radioactive and must be stored underground for a quarter of a million years [250,000].

.> Residual On The Ground: Once the Uranium is unearthed and mined, the mining sites are open scars that release a witch’s brew of material that had been trapped under the earth’s surface before extraction. Many of these old mine sites are highly toxic from the chemicals used and the radioactivity left behind. Most of the world’s toxic mining sites are located on Indigenous lands.

.> This symposium tells the womb to tomb story of Uranium. The presenters discuss the roles and responsibilities of both Art And Science to analyze and reflect upon human use of the atom to generate electricity and create weapons.

やっとRacket言語のpictで少しぐらい納得いく図を作れました。
#小出裕章 さんの #原発の流れ の図 と #原発の場から見た温暖化 の資料 から 出発した図。

.> 本作では、鉱石からイエロー・ケーキ（ウランの黄色い粉末）を精錬する過程で大量の放射性廃棄物が発生する事実を淡々と映し出す。ヨアヒム・チルナー監督は2005年から５年間、旧東ドイツ時代のウラン鉱山跡地、現在もウランを産出するカナダやナミビアの採掘現場の実態を取材した。

.> チルナー監督は「ドイツは65億ユーロ（約7000億円）をかけて後処理をしている。原子力エネルギーが人間の手には負えないことを如実に表している」と指摘する。さらに映画では、肺がんを患った元鉱山労働者が登場し、多くの仲間をがんで失った事実を明かす。

.> 「安全な仕事だと思うか」という監督からの問いかけに対して、「わからない。安全だと言いたいが確信はない。毎月必ず体を壊す人がいる」と不安そうな表情を浮かべる。放射線の被爆限度は知らされていないという。

.> 監督と対談を行ったブロードキャスターのピーター・バラカン氏は、「福島原発事故は、日本政府、東京電力だけでなく、喜んでだまされた国民の責任も大きい。起こした失敗は事実なので、どう責任を取るか考えなければいけない」と語る。
