Comprehensive Guide to Radiation: Types, Uses, and Safety Risks

This guide explores various types of radiation, including infrared, visible light, microwaves, ultraviolet, gamma rays, and X-rays. It details their applications such as cooking, medical imaging, sterilization, and telecommunications. Additionally, the document highlights both the dangers and safety measures associated with exposure to different radiations, noting that while some can be harmless, others can cause serious health issues, including skin burns and cancer. Understanding these aspects is essential for safe usage in everyday life and professional applications.
