* Radiation usually refers to the emission of energy as electromagnetic waves or particles. Lightning does emit electromagnetic radiation, but it's primarily in the form of light and radio waves, not the ionizing radiation you might think of.
* Lightning's primary energy release is in the form of heat and light. The intense electric discharge creates a rapid heating of the air, leading to the bright flash we see.
* While lightning does produce some X-rays and gamma rays, these are extremely small amounts compared to the energy released as light and heat. They are also not considered a significant hazard.
In summary: Lightning is a powerful electric discharge that produces light, heat, and some electromagnetic radiation. While it does emit some X-rays and gamma rays, these are minimal compared to the other forms of energy released, and they are not considered a significant health risk.
