A Compton scattered electron: Is absorbed within a few microns of the site of the original Compton interaction. What is the result of coherent scattering? Usually just a small angle change in the direction of the incident photon. Nonstochastic biologic effects from radiation have a dose threshold; stochastic biologic effects from radiation do not . Stochastic biologic effects from radiation occur as a direct function of dose. Although malicious. Malicious damage is an act that intentionally or deliberately causes damage to personal, private or commercial property. Examples of malicious damage include vandalism and graffiti. -may result after exposure to any type of radiation. biologic damage occurs as a result of ionization of atoms on master, or key molecules (DNA), which causes these molecules to become inactive or functionally altered. -may result after exposure to any type of radiation. biologic damage occurs as a result of ionization of atoms on master, or key molecules (DNA), which causes these molecules to become inactive or functionally altered. biologic damage that occurs as a result of ionization of atoms on master, or key, molecules (DNA) that causes these molecules to become inactive or functionally altered LET The average energy deposited per unit length of track Covalent cross-links chemical unions created between atoms by the single sharing of one or more pairs of electrons. How long will this process continue? a. . Free radicals can cause biologic damage by destroying the chemical bonds of molecules and by dislodging electrons from their orbits. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. When the quantity of radiation energy deposited in living tissue is high enough, biological damage can occur as a result of chemical bonds being broken and. ___________mutations could result from a single alteration along the. Biologic damage begins with the ionization produced by various types of radiation. True T/F- Selection of kVp usually is based on the type of procedure and body part to be radiographed. T/F- Biologic damage in the patient may result from the absorption of x-ray energy. True T/F- Selection of kVp usually is based on the type of procedure and body part to be radiographed. T/F- Biologic damage in the patient may result from the absorption of x-ray energy. electrons; positively. A diagnostic x-ray beam is produced when a stream of high-speed _____ bombard a _____ charged target in a highly evacuated glass tube. energy; energy. Although all photons in a diagnostic x-ray beam do not have the same _____, the most energetic photons in the. Biologic damage may result from the _____ of x-ray energy. Biological deterioration or damage meaning damage or decomposition, breakdown, and/or decay of manmade or natural material due to the presence of fungi, algae, lichens, slime, . Thus, all biological damage effects begin with the consequence of radiation As a result, living cells can be classified according to their rate of. As well, the reactive oxygen can damage enzymes that function to repair damaged DNA. There is evidence that radiation damage in one cell can be passed on to neighbouring cells. Even the neighbouring cells may be damaged genetically. DNA can be damaged, as can components called bases, which are assembled to form DNA strands. Even the neighbouring cells may be damaged genetically. DNA can be damaged, as can components called bases, which are assembled to form DNA strands. As well, the reactive oxygen can damage enzymes that function to repair damaged DNA. There is evidence that radiation damage in one cell can be passed on to neighbouring cells. Lung cancer prevention among smokers, ex-smokers and lifetime nonsmokers can be enhanced as we learn more about the etiologic mechanism(s) of. Free Radicals Solitary atoms, or most often a combination of atoms, that are very chemically reactive as a result of the presence of unpaired electrons. Indirect Action. Biologic damage that occurs as a result of ionization of atoms on essential molecules, which may cause these molecules to become either inactive or functionally altered. A central tenet in understanding the biological effects of ionizing radiation has been that the initially affected cells were directly. All these processes lead to. Biological damage can lead to cellular death, which can occur over time periods from seconds and up to years. Mechanism of tissue radiation damage Direct effect if a biological macromolecule (e.g. DNA, RNA, protein) becomes ionized or excited by an ionizing particle passing through or near it Indirect effect. Mar 29, · Biomolecular radiation damage may result from exposure of biological tissues to ionizing radiation from direct exposure, or via Compton scattering. DNA, RNA, protein) becomes ionized or excited by an ionizing particle passing through or near it Indirect effect. Biomolecular radiation damage may result from exposure of biological tissues to ionizing radiation from direct exposure, or via Compton scattering. Mechanism of tissue radiation damage Direct effect if a biological macromolecule (e.g. As about 80% of the body consists of water, the vast majority of the interactions with ionizing radiation are indirect. Both of these substances are highly reactive and produce biological damage. By themselves, free radicals may transfer excess energy to other molecules, thereby breaking their chemical bonds and having an even greater effect. IR also causes the accumulation of endogenous reactive oxidative species. Hence, cells have developed DNA damage responses and repair mechanisms. 8 Nov Interaction of radiation with biologic systems results in a variety However, if they remain damaged, eventual deleterious effects may be.

  • Direct action biologic damage occurs as a result of ionization of atoms on master, or key molecules (DNA), which causes these molecules to become inactive or functionally altered. -may result after exposure to any type of radiation. results in the formation of structurally changed molecules that may impair cellular function. The most serious biological damage. 1 Sep When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. Delayed effects. These can be due to direct or indirect mechanisms, and they can be acute or delayed. Acute effects occur with exposure to high-level radiation. Cellular damage can be produced by direct action or indirect action. Direct action occurs when the DNA is directly hit by a radiation photon, which can result in single-stranded breaks in DNA and two or more strand breaks. Indirect action occurs through the radiolysis of water leading to the production of free radicals. Exposure to radiation can cause biologic damage.

Which of the following is an example of stochastic effects? 3 Jun However, if the damage is not repaired correctly, a cell may die or It can also result in long-term health effects such as cancer and. The final step (i.e., the expression of the biologic alteration produced in the important biomolecules in the previous stage) is the biologic damage that is tied to the fate of these altered biomolecules. Reactions of H· and OH· radicals with important biologic molecules cause most radiation damage observed in living systems. 2 and 3 only d. 1. The biologic response to ionizing radiation is directly proportional to the dose 2. No known level of radiation dose is believed to be absolutely "safe." 3. 1, 2, and 3. Some biological effects will be caused in living organisms by even the smallest dose a. 1 only b. 1 and 2 only c. Ionising radiation can be considered as a 'two-edged sword' in that it may lead to genetic modifications in exposed, surviving normal tissue, but may lead to.
