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 rate at which energy is absorbed by the body when exposed to RF is referred to as the specific absorption rate, or SAR.

FORBES: Should The FCC Re-Examine Cell Phone Radiation?

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.

CNN: Scientists debate possible cell phone link to brain cancer

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.
