This impressive chart assembled by the web-based science "comic" XKCD shows how doses scale up in sieverts, the units by which absorption of radiation into living tissue is measured.

网上的“科学漫画”XKCD整理出一个令人印象深刻地图标，集中展示了辐射剂量的西韦特单位量——这是测量生物组织对放射性的吸收水平的单位。

They are also looking into how changing certain gut bacteria may prevent obesity by remodelling intestinal tissue and thereby decreasing the absorption of nutrients in the gut.

他们也正在研究某种肠道细菌的改变可能会如何通过改变肠道组织结构来阻止肥胖，从而降低肠道中营养成分的吸收。

Computer software analyses the total absorption of the light and detects the pulsating component of the absorption that originates from cyclic arrival of arterial blood in the tissue.

The Australian research focused on the thermal effects or specific absorption rate (SAR) of radio frequency radiation - a measure of its actual effects on brain tissue, whereas the earlier study simply looked at electromagnetic radiation levels.

The Federal Communications Commission limits cell phone radio frequency energy emissions, called the specific absorption rate (SAR), at 1.6 watts per kilogram, as measured over one gram of tissue.
