In
these two studies the effect of RF radiation on
liver carcinogenesis was investigated. Six week-old
rats were given a dose of diethylnitrosamine (DEN),
which promotes liver cancer. The RF radiation
was given for 90 minutes per day, 5 days per week,
over 6 weeks, and was started 2 weeks after the
DEN injection. At 3 weeks (one week after the
RF exposure was started) the rats had 2/3 of their
liver removed, and at week 8 the rats were killed.
In
the first study, the radiation was a pulse-modulated
929.2 MHz near-field of time division multiple
access (TDMA) signal. The whole-body average SAR
was 0.58-0.80 W/kg. The peak SARs within the liver,
the target organ, were 1.7-2.0 W/kg. There were
no significant differences between the exposed
and control groups in areas of carcinogenic potential
within the liver.
The second study used a 1.439 GHz EM field. The whole-body average SARs were 0.453-0.680 W/kg. The peak SARs within the liver were 0.937-1.91 W/kg. Again, there were no significant differences between the exposed and control groups in areas of carcinogenic potential within the liver. |
