Yup. That is the kind of study you want. And you can note that these are studies of a transmitter being held against the brain as close as possible, that the radiation measured still is too low in energy to trigger normal cancer pathways (what is found is a slight increase in metabolic rate, i.e. the brain works a little bit harder at something), and that all involved stress that nothing that is found is harmful. And when a transmitter that is basically jammed straight into your cortex, with a signal strength that is strong enough to reach a cell tower a few miles away, can't effect more than possibly a slight increase in metabolism - How do you think your much weaker, much more distant WiFi AP can affect you?
