Uranium-236 (236 U or U-236) is an isotope of uranium that is neither fissile with thermal neutrons, nor very good fertile material, but is generally considered a nuisance and long-lived radioactive waste. It is found in spent nuclear fuel and in the reprocessed uranium made from spent nuclear fuel.

Uranium-236 has a half-life of about 23 million years; and is neither fissile with thermal neutrons, nor very good fertile material, but is generally considered a nuisance and long-lived radioactive waste. It is found in spent nuclear fuel and in the reprocessed uranium …

The following table shows the atomic nuclei that are isotonic (same neutron number N = 144) and isobaric (same nucleon number A = 236) with Uranium-236. Naturally occurring isotopes are marked in green; light green = naturally occurring radionuclides.

German submarine U-236 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 23 March 1942 at the Friedrich Krupp Germaniawerft yard at Kiel as yard number 666, launched on 24 November and commissioned on 9 January 1943 under the command of Oberleutnant zur See Reimar Ziesmer.

Sunk on 14 May 1943 inside pontoon No. 5 of the Germaniawerft shipyard in Kiel, by bombs during US air raid (8th AF). No casualties. Raised on 22 May 1943, repaired and returned to service on 29 September 1943.

236 U 是一种人为放射性核素，由 235 U (n, γ) 和 238 U (n, 3n) 的核反应产生。 在环境、地质、核应急、核取证等领域受到广泛关注。 由于独特的理化性质和不同来源的指纹特征明显， 236 U已成功应用于环境示踪、核材料来源认定、环境评价等领域。 到目前为止，关于 236 U 的数据库、应用和最新分析技术发展的评论很少发表。 在这篇评论中， 236 U 浓度和 236 U / 238 总结了U同位素比值，将数据分为四类，包括受全球沉降物和核事件影响的土壤和海水样本。 此外，还总 …

Uranium 236. Uranium 236 is not a naturally occurring isotope of uranium. It is a manufactured isotope found in spent nuclear fuel or reprocessed uranium. The presence of this isotope in a sample of uranium is evidence that the sample has been in a nuclear reactor. Isotope 236 U is formed in a nuclear reactor from fissile isotope 235 U.
