What type of radiation are VHF and UHF radio signals?
Which of the following frequencies has the lowest value for Maximum Permissible Exposure limit?
What is the maximum power level that an amateur radio station may use at VHF frequencies before an RF exposure evaluation is required?
What factors affect the RF exposure of people near an amateur station antenna?
Why do exposure limits vary with frequency?
Which of the following is an acceptable method to determine that your station complies with FCC RF exposure regulations?
What could happen if a person accidentally touched your antenna while you were transmitting?
Which of the following actions might amateur operators take to prevent exposure to RF radiation in excess of FCC-supplied limits?
How can you make sure your station stays in compliance with RF safety regulations?
Why is duty cycle one of the factors used to determine safe RF radiation exposure levels?
What is the definition of duty cycle during the averaging time for RF exposure?
How does RF radiation differ from ionizing radiation (radioactivity)?
If the averaging time for exposure is 6 minutes, how much power density is permitted if the signal is present for 3 minutes and absent for 3 minutes rather than being present for the entire 6 minutes?
