In 2016 the Anthropocene Working Group (awg), an appendage of the International Union of Geological Sciences (iugs), voted in favour of adopting it in principle.

2016年，国际地质科学联合会的附属机构，人类世工作组投票赞成在原则上采用这一标准。

The isotopes that the awg have in mind have half-lives of 6,500 and 24,000 years, meaning almost all the plutonium will be gone within 200,000 years.

人类世工作组所考虑的同位素的半衰期分别为6500年和24000年，这意味着几乎所有的钚都将在20万年内消失。

Indeed, the awg has proposed that the subsequent spike in plutonium-an element which was vanishingly rare before the atomic age-should serve as the " primary marker" for the beginning of the Anthropocene.

事实上，人类世工作组已经提出，钚(一种在原子时代之前非常罕见的元素)随后的峰值应该作为人类世开始的“主要标志”。

(For instance, the start of the Edicarian period, 635m years ago, is defined by a visible change in a band of exposed rocks in southern Australia.) The awg's announcement marked the end of a years-long search for a suitable marker for the Anthropocene.

(例如，6.35亿年前伊迪卡利亚时期的开始，是由澳大利亚南部裸露岩石带的明显变化确定的。)人类世工作组的宣布标志着长达数年的寻找人类世合适标志工作的结束。
