I. Introduction to Ionizing Radiation: i. What is Ionizing Radiation? Ionizing radiation is any type of particle or electromagnetic wave that carries enough energy to ionize or remove electrons from an atom. There are two types of electromagnetic waves that can ionize atoms: X-rays and gamma-rays. X-rays and gamma rays are both types of high energy, high frequency electromagnetic radiation that have no charge or mass (weight) propagating as a bundle of energy known as photons. Both X-rays and gamma

Effects of Radiation Radiation is the emission of electromagnetic energy that is given off in the form of high speed particles that cause ionization. During ionization radiation hits and knocks electrons from an atom creating charged ions. Due to the electron being stripped away from the atom this break the chemical bond. Living tissue within the human body is damaged and attempts to repair it but sometimes the damage is beyond repair. Radiation can either be ionizing or non-ionizing depending
Physics Background Radiation therapy is used to destroy cancer cells because when an ionizing radiation beam interacts with matter, such as tissue cells, ions produced by the interaction damages DNA (International Atomic Energy Agency, n.d.). Ionizing radiation is produced through the products of radioactive decay. Directly ionization radiation includes alpha decay and beta decay products. Alpha decay occurs when an unstable nucleus emits an alpha particle (also known as a helium nucleus) in order
phones can provide us with everything, like relaxing with music, browsing the internet, chatting on social networking sites or playing games. Unfortunately cell phones are not risk free. Using cell phones involve emission of EMR electromagnetic radiation, which is a dangerous sort of energy wave, is produce by modern appliances that surround us in everyday lives. The worst causes of EMR are cell phones. These days especially children are getting addicted to cell phones. When you are talking on your
about both radiation and its effects. It is my belief that nuclear power is no less safe than any other form of energy generation, and can produce significant amounts of power. Very few people truly understand how radiation works, or even what it means. When most people use radiation, they usually mean ionizing radiation, the kind of radiation that causes electrons to leave the atom, thusly ionizing it. Ionizing radiation, like ultraviolet rays from the sun, or x-rays, is harmful, non-ionizing radiation
This chapter discusses the examples of radiation particles that can be detected. This chapter also elaborates on some of the common radiation sensors that are possible to be used in this research as well as different types of kinematic models of mobile robot. The available developed path planning including the waypoints sweeping pattern and other applicable sensors for mobile robot are also discussed in this chapter. Overview of Ionizing Radiation Radiation is the process of emitting radiant energy
Radiation has always been in everyday life even before Roentgen discovered x-ray. The mountains give off natural radiation, other forms of radiation are coal burning power plants, x-rays from a TV, and an airplane ride. The average dose from background radiation is about 360 mrem every year. There are two types of radiation, nonionizing and ionizing radiation. Examples of nonionizing radiation are microwaves and radio waves broadcasting. Ionizing radiation refers to gamma and x-rays. Ionizing radiation
medical treatment; we will be looking at radiotherapy. Radiation therapy usually refers to the ionizing radiation. Ionizing radiation is mostly used in oncology, but it can be used for other purposes such as ionizing an overactive thyroid. The radiotherapy allows the hindering of fast reproduction of cancer cells ("Radiation Therapy"). There are two ways of using radioactive therapy. One is to undergo the therapy from outside the body using radiation from radioactive
Radiation Have you ever been to the doctor and got an X-Ray? If so, you have just been exposed to radiation. Radiation is the emission of energy from any source. Two examples of radiation are light that comes from the sun and the heat that is constantly coming off the human body. Electromagnetic spectrum is the range of wavelengths or frequencies in which electromagnetic radiation extends. The wavelengths range from low energy (low-frequency) to high energy (high-frequency). Radiofrequency radiation
Health effects and Hazards of Radiation Estefanie Garcia Carrington College Krista 11-2-2017 Health effects and Hazrads of Radiation Radiation is one of the most dangerous and easiest way of having health effects. Radiation was first discovered by Roentgen. Hazards are the first things people need to know in order to understand what it can do to your body. It causes many health effects on everyone out in the world. It harms people in the dentistry and field and even in the medical field
What is radiation? Radiation is energy that comes from a source and travels in the form of waves or high speed particles. Radiation is mainly released from atoms, which is the smallest particle of matter. When radiation is emitted, it excites the orbiting electrons in atoms and causes the electrons to vibrate, which emits the energy. There are two types of radiation, namely Ionizing radiation and non-ionizing radiation. Non- ionizing radiation has a low energy level and therefore cannot change
STERILIZATION: Sterilization is the killing or removal of all microbes including bacterial spores which are highly resistant. CLASSIFICATION: Moist heat sterilization. Dry heat sterilization Chemical sterilization. Sterilization is also classified as SUNLIGHT: Bactericidal activity. Germicidal activity because of U V rays + heat. DRYING: Sterilization by dry heat on the other hand requires temperature in range of 1800C for 2 hours.This process is used primarily for glassware . Spores are unaffected
the human body without breaking the skin. By using radiant energy, which may take the form of x rays or other types of radiation, we are able to diagnose and treat many diseases and injuries. Both diagnostic and therapeutic radiology involve the use of ionizing radiation ( Beta, Alpha, Gamma, and x rays), with the exception of the MRI, which uses a magnetic field rather then radiation. Radiology is classified as being either diagnostic or therapeutic. Diagnostic radiology is an evaluation of the
found to emit alpha radiation, a highly hazardous type which is also emitted by Uranium. It has been concluded that plutonium has a higher radioactivity, hence a faster half-life. What is Radiation? Radiation is excess energy, which travels through space in the form of heat, light, sound, microwaves, radio waves and x-rays. Low radioactive substances can be found everywhere. When much more sophisticated elements are subject to decay, they release many types of radiation; the most common are
prevent exposure to themself?" The radiation dose for each exam is relatively small, but over time, the dose can add up. There are many state and federal regulations limiting the total radiation dose that may be received by people working with radiation. To comply with those regulations, the technologist must follow strict precautions to keep their cumulative exposure to a minimum. Although no adverse health effects have been directly linked to low-dose radiation exposure, the medical community is
Consequences of the Chernobyl Accident Radiation has both beneficial and harmful effects. The most detrimental health effect on humans, is the incidence of cancer, which has been studied. Humans are exposed to radiation more than they realize. They are exposed medically with x-rays, just by being outside with cosmic rays, and by accidents such as at the Chernobyl Nuclear Power Plant. Exposure to radiation is high and more studies are done which improve radiation protection. The Chernobyl disaster
has helped people since then. Even though the X-ray can have many advantages, it can also have disadvantages that limit its use. If exposed to long, or to too strong rays a process called ionizing radiation can happen. In this process any living tissues in a human body can be damage; because ionizing radiation (with enough s... ... middle of paper ... ...at may affect the body. I think society takes great advantage of the X-ray and does not appreciate it enough. Without such an amazing invention
damage in ischemic conditions, the process may provide ways for therapies in suicide gene therapy, chemotherapy and radiotherapy. These treatments utilize the nature of the bystander effect to deliver either lethal genes, anticancer agents or ionizing radiation to local carcinogenic cells and the cells neighboring them. With the growing understanding of the bystander effect, lower dosages of agents can be used to spare healthy unaffected cells. In suicide gene therapy, the main objective is to induce
innovations; however, progress of the past is, systematically, detrimental to the future. Not long after the revolutionary invention of the X-ray in the late 19th Century, an unprecedented number of medical examiners noticed (unknown to the time) radiation burns all over their body; decades later, an extraordinary surge in cancer cases had arisen. Perhaps, during the course of these years, scientists and researchers desired to further progress the x-ray (into the immense subsidiaries that are here
