radioactive heat

The syenite is enriched in large ion lithophile elements, radioactive heat-generating elements, high field strength elements and LREE and depleted in Sr and Ba and has weak negative Eu anomalies.

岩石富集大离子亲石元素、生热元素和轻稀土元素，贫Sr、Ba，具弱的Eu负异常。

The primary heat exchanger ( PHX) is a key heat transmission equipment of the lead alloy cooled reactor, and it is also a safety barrier to prevent the radioactive lead alloy coolant.

主换热器是铅合金冷却反应堆中关键的热传输设备，同时也是防止一回路放射性冷却剂外逸的一道安全屏障，此外，换热器结构设计合理性也将直接影响反应堆安全性及经济性。

We don't know what astatine looks like, because, as Lowe put it, "that stuff just doesn't want to exist." It's so radioactive ( with a half-life measured in hours) that any large piece of it would be quickly vaporized by its own heat.

我们不知道砹看上去是什么样子的，正如劳维所说：“这玩意儿根本就是不想存在。”砹具有极强的放射性（半衰期以小时计算），任何一块稍微大一点儿的砹块都会被自身衰变释放出来的热量气化掉。

In an extensional basin, the surface thermal flux could be controlled by several factors such as the thermal flux derived from mantle, radioactive heat generation of the upper crust and sediments, and the thermal conductivities of lithosphere and sedimentary strata.

伸展盆地的大地热流值可以认为是由地幔热流、地壳内部和盆地沉积物生热效应以及岩石圈和沉积物导热性质等多个因素综合叠加的结果。
