Radiation refers to the emission of energy in the form of waves or particles. It can be classified into ionizing radiation (such as X-rays and gamma rays) and non-ionizing radiation (such as visible light and radio waves). Exposure to high levels of ionizing radiation can be harmful to human health, causing damage to cells and DNA.

What is infrared radition?
Infrared radiation is a type of electromagnetic radiation with longer wavelengths than visible light. It is commonly associated with heat and is used in various applications such as thermal imaging, remote controls, and infrared saunas.
Can you get hurt from infrared radition?
Infrared radiation does not penetrate deep into the body and typically only affects the skin. Prolonged exposure to high levels of infrared radiation can cause skin burns and damage, similar to sunburn. It is important to avoid excessive exposure to infrared sources and follow safety guidelines.
How was microwave radition discovered?
Microwave radiation was discovered by physicist Percy Spencer in 1945. He noticed that a candy bar in his pocket melted while working with a magnetron, a vacuum tube that generates microwaves. Spencer then conducted further experiments using popcorn and an egg, leading to the development of the first microwave oven.
How do you prevent conduction convection and radition?
To prevent conduction, use materials with low thermal conductivity. To prevent convection, minimize temperature differences within a space by using proper insulation and sealing gaps. To prevent radiation, use reflective barriers or absorptive coatings that block or reduce the transfer of radiant heat.
How does microwave radition get to the brain?
Microwave radiation can reach the brain through exposure to microwaves emitted by microwave ovens, mobile phones, or other electronic devices. When these devices are held close to the head, the radiation can penetrate the skull and reach the brain tissue.
