What is one effect of high duty cycles on RF radiation exposure?

High duty cycles refer to the amount of time a transmitter is operating compared to the time it is turned off. When the duty cycle is high, this means the transmitter is transmitting continuously or for a longer duration. The effect of a high duty cycle on RF radiation exposure is to increase the average exposure to radiation.

This is primarily because the energy emitted by the RF source is generated over an extended period of time, leading to a higher cumulative output of radiation in a given timeframe. Consequently, individuals or equipment in proximity to the transmitter will experience greater levels of RF radiation exposure, which can contribute to safety concerns and regulatory limits regarding exposure levels.

In contrast, lower duty cycles would lead to less average exposure, as the transmitter would be off for a significant portion of time, allowing for intervals in which no radiation is emitted. Therefore, a high duty cycle is a critical factor to consider in understanding and managing RF radiation safety.
