If you talk on a cell phone for an hour If you talk on a cell phone for an hour each day, the amount of radiation each day, the amount of radiation that you will receive for a year would that you will receive for a year would be be 10951095 wattswatts..

CalculationCalculation

1 hour a day x 365 days a year=365 1 hour a day x 365 days a year=365 hrs.hrs.

365 hours x 3 watts= 1095 watts in a 365 hours x 3 watts= 1095 watts in a year.year.
