The electromagnetic spectrum is broken up into two parts based on whether small doses of that radiation can cause harm: ionizing radiation and non-ionizing radiation. Street vendors used to follow crowds around, pushing steam or gas-powered poppers through fairs, parks and expositions. This vibration creates heat, which in turn pops the kernels and produces the popcorn. Others believe that the hot air circulated by the convection setting will eventually cause the popcorn to burn.
