HISTORY OF ENVIRONMENTAL RAPID CLIMETE CHANGE IN CANADIAN ICE CAPS : RELATIONSHIP BETWEEN NUCLEAR EXPLOSIONS AND VOLCANIC ERUPTIONS.

长崎A-炸弹的科学方面被调查，许多有趣的事实被揭示如下：（1）长崎D 1239 + 240 D-1 Pu和D-1137 D-1 Cs的数量分别为13.8公斤和23.4克，对此表示赞赏。（2）长崎市的当地辐射为37.5克（或9.48 × 10 × D110 × D1 Bq），适用于D1239 + 240 × D1 Pu和3.14毫克（或5.88 × 1010 Bq），适用于D1137 × D1Cs。（3）长崎钚的质量平衡为1.2公斤，用于飞行反应，37.5克用于当地的粪便，其余部分则被用于全球粪便。（4）There was a clear difference in the amount of local fallout between y D1239 + 240 y D1Pu and y D1137 y D1Cs.放射性发光释放到环境中的机制可能会造成不同的影响。（5）The deposition rate ofイイD1239 + 240イエD1Pu andイイD1137イエD1Cs derived from Nagasaki at Agassiz ice cap，Canada was 0.16 μ Bq/cmイイD12イエD1 forイD1239 + 240イエD1Pu and 20 μ Bq/cmイD12イエD1 forイD137イエD1Cs。（6）The transport rate ofイイD1239 + 240イエD1Pu andイイD1137イエD1Cs was widely different。The reason of this difference might be explained by the production process ofイイD1137イエD1Cs。（7）假定在未来10，000年的气候中存在一定的稳定性，主要是I-D1239 + 240 I-D1Pu，可以在Agassiz冰帽上从97 - 98米处探测到冰层之间97 - 98米处的雪表面。即使在使用放射性分析方法的情况下，1945 - 1980年的冰层也可以很容易地用目前的分析技术识别出来。希望这一研究能找到一种方法来使用我们这一代人的艺术品，对我们未来后裔的益处。]

The scientific aspect of the Nagasaki A-bomb was investigated and many interesting facts were revealed as follows : (1)The amount of Nagasaki ィイD1239+240ィエD1 Pu and ィイD1137ィエD1 Cs released was 13.8 kg and 23.4 g, respectively. (2)The local fallout in the city of Nagasaki was 37.5 g (or 9.48×10ィイD110ィエD1 Bq) for ィイD1239+240ィエD1 Pu and 3.14 mg (or 5.88×1010 Bq) for ィイD1137ィエD1Cs. (3)The mass balance of Nagasaki Pu was 1.2 kg for the fission reaction and 37.5 g for the local fallout and the rest was dispersed as the global fallout. (4)There was a clear difference in the amount of local fallout between ィイD1239+240ィエD1Pu and ィイD1137ィエD1Cs. The mechanism of the release of radionuclides to the environment may have caused the difference. (5)The deposition rate of ィイD1239+240ィエD1Pu and ィイD1137ィエD1Cs derived from Nagasaki at Agassiz ice cap, Canada was 0.16 μBq/cmィイD12ィエD1 for ィイD1239+240ィエD1Pu and 20 μBq/cmィイD12ィエD1 for ィイD1137ィエD1Cs. (6)The transport rate of ィイD1239+240ィエD1Pu and ィイD1137ィエD1Cs was widely different. The reason of this difference might be explained by the production process of ィイD1137ィエD1Cs. (7)Assuming there was a consistency in climate for the next 10,000 years, the chronological anthropogenic deposits, mainly of ィイD1239+240ィエD1Pu, could be detected in the ice layer between 97-98 m from the snow surface in 11,999 AD on the Agassiz ice cap. Even if there were no improvements in the radioactive analytical method used, the ice layers for the 1945-1980 period could still be easily identified with the present analytical technology. Hopefully this study will find a way to use our generation's artifacts for the benefit of our future descendants. ]
