Understanding What Radiation Is
Radiation is energy that travels from one place to another in the form of waves or particles. It exists all around us, both in nature and in modern technology.
Types of Radiation
Radiation comes in two categories: non-ionizing radiation, such as visible light and microwaves, and ionizing radiation, such as X-rays and gamma rays.
How Radiation Works
When radiation moves through space or matter, it transfers energy. This can create heat, produce light, or affect atoms depending on the type and strength of the radiation.
Natural and Everyday Sources
The Sun, rocks, electronic devices, medical scans, and even the human body emit radiation. Most of it is harmless and part of normal life on Earth.
When Radiation Becomes Harmful
Strong ionizing radiation can damage cells and DNA. This is why protective measures are used in medical imaging, nuclear facilities, and high-energy environments.
Why Radiation Is Useful
Radiation plays a key role in medicine, communication, research, and energy production. It enables cancer treatments, X-rays, wireless signals, and scientific discoveries.
The Simple Takeaway
Radiation is energy that travels as waves or particles. It can be useful or harmful depending on its type and intensity.
