Procedure:Procedure: 200 mice- 100 exposed to pulsed 200 mice- 100 exposed to pulsed digital phone radiation; 100 controlsdigital phone radiation; 100 controls
Result:Result: Significant increase in B-cells (implicated in 85% of all Significant increase in B-cells (implicated in 85% of all

ProblemProblem: Mice sometimes exposed to 20 hours : Mice sometimes exposed to 20 hours of radiation!! Therefore, not very comparable to of radiation!! Therefore, not very comparable to humanshumans
