WHAT IS RADIATION? Radiation is the process by which energy is emitted as either particles or waves. Broadly, it can take the form of sound, heat, or light. However, most people generally use it to refer to radiation from electromagnetic waves, ranging from radio waves, though the visible ...
When matter is subjected to bombardment by high energy radiation, radiation particle is leaving a trail of disrupted atoms and molecules. One source of radiation is the cosmic rays from outer space. The dose received from a radiation source depends on many factors such as the type and the ...
Step-by-Step Solution:1. Definition of Radiation: Radiation is defined as the emission and propagation of energy in the form of waves, rays, or particles. This means that energy can travel through space in
What is radiation therapy? This lesson will outline what it is, what it's used for, different types, and the possible side effects from this treatment. What Is Radiation Therapy? Radiation therapy is a type of treatment used to attack cancer cells and shrink tumors. Radiation therapy uses ...

You may have heard that iodine is vital for the endocrine system, including thyroid health and the reproductive system. You may also know that iodine can protect you if you ever become exposed to too much radiation. But did you know that there are dozens of other beneficial uses for iodine...
This is considered "good" ozone, which occurs naturally and helps block harmful radiation from the Sun. But there is also ground-level ozone. It's exactly the same gas, but it's found closer to the surface of the Earth. This ground-level ozone results from human activities, and at high...
Infrared radiation (IR), sometimes referred to simply as infrared, is a region of the electromagnetic radiation spectrum wherewavelengthsrange from about 700 nanometers (nm) to 1 millimeter (mm). Infrared waves are longer than visible light waves but shorter than radio waves. Correspondingly, the...
Because they are radioactive, radon and radon progeny emit alpha particles, a high-energy radiation that damages DNA in human cells and causes lung cancer. When radon is inhaled, particles become lodged in the lungs where they continue to emit alpha particles. ...
