摘要

审查目的:本综述深入探讨了如何解决与处置含大量铀的废物(铀废物)有关的代际问题,因为这些废物对后代造成的健康风险高于当代人:最新发现:铀(半衰期:45 亿年)通过长期放射性衰变产生各种后代放射性核素,其放射性作为其贡献的总和,在超过 10 万年的时间里持续增加。与高放射性废物不同的是,辐射衰减和将放射性核素封闭在处置设施之外等保护措施无法对铀废物有效发挥作用。因此,在铀废料处置战略中,需要从代际伦理的角度进行额外的考虑。这一代人从铀废料的使用和处置中获益,他们有责任保护子孙后代在处置设施寿命结束后免受被掩埋铀的潜在风险。履行这一责任意味着要做出更多创造性的努力,向遥远的未来传递有关掩埋材料的重要信息,以确保后代能够根据不断变化的情况(包括人们的价值观),自行采取适当的措施来减少危害。

Consideration on the Intergenerational Ethics on Uranium Waste Disposal.

Purpose of review: This review provides insights into resolving intergenerational issues related to the disposal of waste containing high amounts of uranium (uranium waste), from which distant future generations will have higher health risks than the current generation.

Recent findings: Uranium (half-life: 4.5 billion years) produces various progeny radionuclides through radioactive decay over the long term, and its radioactivity, as the sum of its contributions, continues to increase for more than 100,000 years. In contrast to high-level radioactive wastes, protective measures, such as attenuation of radiation and confinement of radionuclides from the disposal facility, cannot work effectively for uranium waste. Thus, additional considerations from the perspective of intergenerational ethics are needed in the strategy for uranium waste disposal. The current generation, which has benefited from the use and disposal of uranium waste, is responsible for protecting future generations from the potential risk of buried uranium beyond the lifetime of a disposal facility. Fulfilling this responsibility means making more creative efforts to convey critical information on buried materials to the distant future to ensure that future generations can properly take measures to reduce the harm by themselves in response to changing circumstances including people's values.
