I don't know where the author of the NYT gets these numbers:Those rats need to stop using 90s cell-phones.

The lowest level of radiation in the federal study was equal to the maximum exposure that federal regulations allow for cellphone users. That level of exposure rarely occurs in typical cellphone use, the toxicology agency said. The highest level was four times higher than the permitted maximum.
I have only browsed the Tech Report for rats, but clearly they used SAR 3W/kg, 6W/kg and 9W/kg.
According to here:
"The FCC limit for public exposure from cellular telephones is an SAR level of 1.6 watts per kilogram (1.6 W/kg)."
1.6 < 3
9 > 4 X 1.6
Maybe I need a new calculator or maybe I missed something?
I have not gone through it critically or thoroughly and I probably will not because it would take too much time and I would have to relearn a lot of pathology that I am just fine not remembering.
With all that qualification, I would say the following: They did a serious job and they are presenting all the details (typical of a decent Tech report). It is a collaboration among several groups. They went through a full load of peer review for a Tech report. They do report some effects. I am not seeing a dose-effect and that bugs me a bit. But again, I have not read it thoroughly.
It was mentioned that some exposed animals lived longer than shams. That is true as I recall, but (as pointed out in the report) it is not, necessarily, a meaningful difference. Two years is close to a life span for those rats, but they did not have the appropriate variability measures in the sense that, beyond their sham group, you don't know what the distribution for life span looks like.
As for whether it is clear/some/equivocal evidence, I am not jumping on that because the way to find out is through replication and extension studies to zero in on the effects. I don't think it is likely to happen because of the irrelevancy of 900 MHz. That is actually a shame in my view.
As far as extrapolation to humans, well that is another matter...as usual.
