Staying Safe with Radio Frequency Energy

Learn why Health Canada's Safety Code 6 sets exposure limits to protect you from radio waves. Understand which frequencies are most intense, how distance and power matter, and why no transmitter is exempt from these safety rules.

This lesson is part of SignalPrep Pro. The subsection's 10 exam questions are free to practise: practise B-001-024.
