☢️ What is radiation?

Radiation is like tiny invisible waves or little energy particles that come from some things around us. 🌟 Some radiation is good, like the warm sunlight that helps plants grow! But some can be not so good, like when we use sunscreen to protect our skin.

Radiation can come from the sun, rocks, and even some machines in hospitals. Doctors use special kinds of radiation to take pictures of our bones! 🏥

Radiation is energy that travels as waves or tiny particles. It’s all around us! ☀️ Some types, like light and heat from the sun, are natural and safe. Others, like X-rays, are man-made and used carefully by doctors.

There are two main types:

• Natural radiation: From the sun, rocks, and even space!
• Man-made radiation: Like X-rays or nuclear power plants.

Too much radiation can be harmful, so scientists measure it with special tools. But don’t worry—most radiation is harmless! 🛡️

Radiation is energy emitted as electromagnetic waves (like light or X-rays) or particles (like alpha/beta particles). It exists naturally and is also created by humans. Here’s how it works:

Types of Radiation:

• Ionizing: High-energy (X-rays, gamma rays) — can damage cells but is useful in medicine.
• Non-ionizing: Lower energy (radio waves, visible light) — mostly harmless.

Natural sources include the sun (cosmic radiation), radioactive elements in rocks (uranium), and even our bodies (potassium-40)! Humans use radiation for:

• Medical imaging (X-rays, CT scans)
• Nuclear power
• Sterilizing food/medical equipment

Protection (like lead shields or limiting exposure) is key for safety. ☢️
