The History of the Discovery of Radiation and Radioactivity Introduction: Radiation can be defined as the propagation of energy through matter or space. It can be in the form of electromagnetic waves or energetic particles. Ionizing radiation has the ability to knock an electron from an atom‚ i.e. to ionize. Examples of ionizing radiation include: • alpha particles • beta particles • neutrons • gamma rays • x-rays Non-ionizing radiation does not have enough energy to ionize atoms in the material

Lit 2 May 2013 History of Cancer: Radiation There is a broad group of different types of cancers and they all have a wide range of causes. Each cancer is different according to its biology and pathophysiology. Cancer is a very broad topic but chose four topics that show that radiation is the main cause of cancer. Before I can prove radiation is the cause of cancer‚ there needs to be an introduction as to what cancer is and how it spreads

The Cardiovascular System: Intrinsic Conduction System 1. The intrinsic conduction system consists of __autorhythmic cardiac______ cells that initiate and distribute __impulses___ throughout the heart. 2. The intrinsic conduction system coordinates heart activity by determining the direction and speed of _heart depolarization___. This leads to a coordinated heart contraction. 3. List the functions for the following parts of the intrinsic conduction system: a. SA Node __initiates the depolarizing

cellular structure. Ionizing radiation causes atoms and molecules to become ionized or excited. These excitations and ionizations can: * Produce free radicals. * Break chemical bonds. * Produce new chemical bonds and cross-linkage between macromolecules. * Damage molecules that regulate vital cell processes (e.g. DNA‚ RNA‚ proteins). The cell can repair certain levels of cell damage. At low doses‚ such as that received every day from background radiation‚ cellular damage is rapidly

Mrs. Pilar M. Macabinguil ENGLISH IV Teacher MPCHS Madam: In partial fulfillment of the requirement in ENGLISH IV‚ I hereby present to you my term paper entitled “What is Radiation?” This term paper presents a research study on the importance about radiation and how it affects the whole world. In doing a research paper is a big task that must be given more efforts‚ time and patient. It will not be built without references. I always think of doing this not for the

including mammography) all use ionizing radiation to generate images of the body. Ionizing radiation is a form of radiation that has enough energy to potentially cause damage to DNA and may elevate a person’s lifetime risk of developing cancer. CT‚ radiography‚ and fluoroscopy all work on the same basic principle: an X-ray beam is passed through the body where a portion of the X-rays are either absorbed or scattered

On the other hand‚ the usage of cell phone had become addictive to people of all around the world and the abuse of prolongated hours on the cell phones can cause health hazard. Cell phones work under a non-ionizing radiation bases. But there is still a concern of how much cell phone usage a person can endure without any harmful reaction to them. I myself believe that cell phones may cause a reduction of blood cell count‚ but I do not believe that cell phones causes
