yes a 'rad' is a measure of absorbed dose, 1oo ergs/gram. it is for any material, not just tissue. for tissue the 'rem' is used and 1 rad = 1 rem. why i asked is because for the low energy radiation a cell phone emits would not penetrate the outer layer of dead skin. so there is no 'absorbed' dose. cell phone use a max frequence of 849 MHz, which converts to 3.5 micro eV, a micro is 0.000001 or a millionth. it take 2 - 5 eV to break molecular bond to tramform DNA. so it seems inconceivable for cell phones to cause tissue damage. BTW i'm a radiation physicist and stayed in a holiday inn express.
