1. It travels through a vacuum with the velocity of light. 2 It travels in a straight line. 3. It undergoes reflection, refraction, and total internal reflection. 4. It exhibits the phenomenon of interference, diffraction, and polarisation. 5. Intensity of radiation decreases with an increase in distance. Advertisement New questions in Physics

The model, called the kinetic theory of gases, assumes that the molecules are very small relative to the distance between molecules. The molecules are in constant, random motion and frequently collide with each other and with the walls of any container. The individual molecules possess the standard physical properties of mass, momentum, and energy.

It involves using high-energy beams or particles to destroy cancer cells. While radiation therapy can be effective, it can also have side effects. In this article, we will explore the most common side effects of radiation therapy. 1. Fatigue: Fatigue is one of the most common side effects of radiation therapy.

LAI is defined as the one-sided green leaf area per unit ground area in broadleaf canopies and as half the total needle surface area per unit ground area in coniferous canopies. FPAR is the fraction of photosynthetically active radiation (400-700 nm) absorbed by green vegetation. Both variables are used for calculating surface photosynthesis.

Photons Most radiation therapy machines use photon beams. Photons are also used in x-rays, but x-rays use lower doses. Photon beams can reach tumors deep in the body. As they travel through the body, photon beams scatter little bits of radiation along their path. These beams do not stop once they reach the tumor but go into normal tissue past it.

Radiation therapy describes treatments that use high-powered waves of energy to destroy the genetic materials (DNA) in cancer cells. Ionizing radiation, the same kind of radiation used in X-rays and gamma rays, is usually used in radiation therapy because it is more powerful than the nonionizing waves that are used in microwave and radio.

Mark Kostich / Getty Images What Is Radiation Therapy? Radiation therapy is a commonly used therapy for many types of cancer. For breast cancer, radiation is typically used after surgery to help reduce the risk of cancer returning. It can also help treat a symptom, such as pain, in someone with cancer that has spread outside the breast.

Temporary side effects of RAI may include: Neck tenderness and swelling. Nausea. Swollen salivary glands.

Mission The Medical College of Georgia Department of Radiation Oncology is devoted to providing superior patient care in an atmosphere of compassion and professionalism.

Radiation therapy uses high-energy rays or particles to kill cancer cells. For most types of bone cancer, the cancer cells are not easily killed by radiation, so high doses are needed. This can damage nearby healthy tissues, including key structures (like nerves and blood vessels) in the area. Because of this, radiation therapy isn't used as a.

In addition, it is important to know which side of the electromagnetic spectrum is deadly. Figure 5.2. 3: The Electromagnetic Spectrum. (a) This diagram shows the wavelength and frequency ranges of electromagnetic radiation. The visible portion of the electromagnetic spectrum is the narrow region with wavelengths between about 400 and 700 nm.
