6. Describe the way in which the above named industrial and medical radioisotopes are used and explain their use in terms of their chemical properties. Cobalt-60 is used in industrial radiography to inspect metal parts and welds for defects. Beams of radiation are directed at the object to be checked from a sealed source of Co-60. Radiographic film on the opposite side of the source is exposed when it is struck by radiation passing through the objects being tested.
What type of incident involves an unusually wide distribution of a disease or simultaneous outbreaks of a disease? (1 point) A. Biological B. Chemical C. Incendiary D. Nuclear 4. What are three primary techniques for minimizing exposure to radiation and radioactive materials?
A dangerous cargo manifest is most commonly associated with which mode of transportation? (1 point) C. Water 19. What chemical agents primarily attack the airway and lungs, causing irritation of the entire airway from the nose to the lungs and resulting in what is commonly known as dry-land drowning? (1 point) C. Choking (CL) 20.Identify one of the difficulties of determining the specific names of hazardous materials in both facilities and transportation. (1 point) B. Placards or labels that are missing 21.Individuals should use the principles of __________, __________, and __________ to avoid chemical agents.
Even though Chemotherapy is used to kill all the cancer’s cells, it also kills the red and white cells in process, giving side effects like, bleeding (nose bleeds) , hair loss, and vomiting (Patlak 21). In cases of only having a small stage of NHL or when Chemotherapy is out of the picture due to the damage Chemo does to the heart, Radiation therapy is a second choice. In some cases, however, both Chemo and Radiation therapy is used simultaneously. Radiation therapy is a high energy x-ray that is used to damage cancer cells and stop them from growing. With NHL doctors often not only aim the radiation to the one site but to the other lymph nodes in the region to make sure the cancer is not hiding in another node.
INCORRECT The most common type of cirrhosis worldwide is actually the result of hepatotoxins, such as viral hepatitis, which cause massive liver necrosis. C) All alcoholics will develop cirrhosis. INCORRECT No more than half of all alcoholics will develop Laennec's cirrhosis, which is the type of cirrhosis related to alcohol consumption. Laennec's cirrhosis is the most common form of cirrhosis in North America. D) Spouses of alcoholics are at risk for cirrhosis.
The main causes of developing Anemia include: medications and pregnancy, but the more serious causes include: kidney disease and cancer of the kidney, also leukemia and lymphoma. A bacterial infection on the Hematocrit can cause the white blood cell count to raise but lower Hematocrit. 2. Lymphocytes and other formed elements develop from Pluripotent cells. Pluripotent stem cells generate Myeloid and lymphoid stem cells.
(Ch52,pg1355) Works Cited: Business Law 14th Edition, Mallor, Barnes, Bowers, Langvardt, Chapter 52, page 1355. Question 2 2.) What is the “Superfund”? Explain and discuss. Superfund is the name given to the environmental program established to address abandoned hazardous waste sites.
The author of the article goes on to say that people in the US are sentenced to do time for crimes that would not produce such a sentence in other countries. According to another article in the New York Times (2008), states spend close to ten percent of their budget on corrections (Liptak &, 2008). In 2007 alone, states spend close to $45 million tax dollars. Not only is simply housing an inmate costly, but healthcare also provides a financial burden. In 1998, the states paid a little over seven dollars a day per inmate for healthcare (Kinsella, 2004).
Jacky Huang Medical Report 10/18/11 1)Cause of Deficiency Cancer is a class of diseases characterized by out-of-control cell growth, and lung cancer occurs when this uncontrolled cell growth begins in one or both lungs. Rather than developing into healthy, normal lung tissue, these abnormal cells continue dividing and form lumps or masses of tissue called tumors. Tumors interfere with the main function of the lung, which is to provide the bloodstream with oxygen to be carried to the entire body. Most lung cancers are the result of inhaling carcinogenic substances. Carcinogens are a class of substances that are directly responsible for damaging DNA, promoting or aiding cancer.
Mixtures of solvent vapours and air can explode. Solvent vapours are heavier then air,they will sink to the bottom and can travel large distances nearly undiluted. Solvent vapours can also be found in supposedly empty drums and cans, posing a flash fire hazard; hence empty containers of volatile solvents should be stored open and upside down.
