1. Safety

2. Handheld Radios (HTs) Generally safe as is
Low Battery Voltage, Enclosed
Low Power gives low RF exposure
Low Power gives low antenna voltage (16Vrms)

3. RF Exposure Non-Ionizing radiation Hazard is said to be Tissue Heating
Microwaves – eyes most vulnerable

4. Maximum Permissible Exposure (MPE)

5. RF Exposure Duty Cycle

6. Thresholds for RF Evaluation
Re-evaluate the station whenever
an item of equipment is changed

7. To Reduce RF exposure: Relocate antennas Reduce Power
Change frequency band
Change antenna radiation pattern
Change antenna heading

8. Electrical Hazards

9. Electrical Hazards P=IV=IE
1. High V, Low I
2. Low V, High I
3. High V, High I

10. Human Body Model

11. Human Body Model DO NOT TRY THIS AT HOME!
A pair of copper wires was connected to a 120V wall plug. The extreme danger of this was explained and then a hotdog was used to short-circuit the wires. The hotdog was cooked and then later eaten by a participant.
DO NOT TRY THIS AT HOME!
