We now know the age of the glaciation accurately from radiometric dating of the carbon-14 in logs buried in the drift.

我们现在通过测量掩埋在漂流物中木头放射性的碳-14元素，以精确地确定冰川作用的时期。

VIIRS will collect radiometric imagery in visible and infrared wavelengths of the Earth's land, atmosphere, and oceans.

VIIRS将在可见光和红外波段收集地球上陆地、大气和海洋的辐射图像。

We also made some radiometric measurements to derive a more precise orbit. This should make it easier to contact Phobos-Grunt in future.

我们还通过辐射测量的方法矫正了轨道，使之更加精确。这有利于我们未来更加容易地与探测器取得联系。

The ease to locate Carbon-14 that would respond to decay currently has put the reliability of radiometric dating method into question.

FORBES: Young Earth Creationists Whipsawed By IRS

The reliability of percentage remaining (50% of the remaining rule) that has been used by scientists for the relative half-lives elapsed in responding to radiometric dating method is in question.
