Had some "nothing to do" time today so decided to spend a few quality minutes performing my "due diligence" with the ARRL's RF Exposure Caculator at

I ran four cases, for all bands from 160m to 6m, making the most conservative of assumptions - zero feedline loss, theoretical dipole gain of 2.14 dBi, calculating with ground reflections, and rounding all distances (for the uncontrolled environment up to the nearest tenth of a foot

Case 1:  100 W out, "brick on the IC-706 key" that is 100% Tx, 24/7
Case 2   100 W out, normal CW , that is 40% Tx  duty,  2 min Tx then 2 min Rx
Case 3:  15 W out,  "brick on the K2 key", that is 100% Tx, 24/7
Case 4:   a Bayou Jumper during normal Secret Agent ops

The results are shown on the attached graph.
