*Question T0C07:
What hazard is created by touching an antenna during a transmission?*  

*Correct Answer is  B: RF burn to skin*  

### AI Response: (may contain errors)

When you touch an antenna during transmission, the primary hazard is:

**Correct Answer: B: RF burn to skin**

### Explanation:

1. **Why the correct answer is correct:**
   - **RF burn to skin** occurs because the antenna radiates radio frequency (RF) energy. If you touch the antenna while it is transmitting, your body can absorb some of this energy, leading to burns. RF burns are similar to thermal burns, as the energy can heat the skin and underlying tissues.

2. **Why the other choices are incorrect:**
   - **A: Electrocution**: This is not typically a hazard with RF antennas unless there is a fault in the electrical system. RF energy does not carry a lethal electric current like AC or DC power does.
   - **C: Radiation poisoning**: This is not applicable in the context of RF energy. Radiation poisoning is associated with ionizing radiation (like X-rays or gamma rays), which is not produced by RF transmissions.
   - **D: All these choices are correct**: Since only RF burns are a valid concern, this choice is incorrect.

### Useful Information:
- **RF Safety Guidelines**: Always maintain a safe distance from transmitting antennas to avoid RF exposure.
- **Power Density**: The potential for RF burns increases with the power density of the RF field, which can be calculated using the formula:

$$
S = \frac{P_T \times G_A}{A}
$$

where:
- $S$ = power density (watts per square meter)
- $P_T$ = transmitter power (watts)
- $G_A$ = antenna gain (linear)
- $A$ = area over which the power is distributed (square meters)

Understanding these concepts will help you recognize the hazards associated with RF energy and ensure safe practices while operating amateur radio equipment.
