You can get an idea of the relative amounts of radiation various cellphone models emit by looking at their SAR, or specific absorption rate.

It was not until the 1950s that scientists had both good data on the absorption of infrared radiation, and digital computers that could speed through the multitudinous calculations.

直到20世纪50年代，科学家才获得了红外辐射的可靠数据，并有了计算机可以帮助进行海量的计算。

Under the new rules, stores will be required to show the Specific Absorption Rate (SAR) of radiation next to phones they sell with a clearly readable 11-point or larger font.

美国旧金山本周二通过了一项手机辐射法，这项法令规定出售手机的店铺必须在销售的手机旁边以11号以上大小的字体标注手机的辐射吸收率指数 （Specific Absorption Rate (SAR)：标示手机辐射能被人体吸收的程度的一种衡量指数）。

That, in turn, results in an increased absorption of solar radiation by the darker ocean surface, which also contributes to warming.

But the strength of the greenhouse effect depends on the chemical composition of the atmosphere, because the phenomenon is due to the absorption of infra-red radiation by various gases in the air.

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.
