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

你可以通过查看不同手机型号的吸收率，来了解手机的辐射。

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）。

The law requires that retailers post the specific absorption rate (SAR) — the amount of radio waves absorbed into the user's body — next to all phones in no less than 11-point type.

该法案规定手机销售商要注明手机的辐射吸收系数(SAR)——对用户身体产生的电磁波吸收量，规定所有手机都不少于11点型式。

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.
