Radiation

vivid and made pictures in your head. The image that stuck with me was during Henrietta’s autopsy one woman said that it looked like her body had been filled with little pearls. Another one was when it talked about her skin being charred from the radiation treatments. I found it interesting yet also disgusting that a human being could put another human being through things like that. This…

Oral Cancer On average, 43,000 Americans are diagnosed with oral cancer per year. Of those 43,000, it will cause over 8,000 deaths. That is one person every hour of every day. This number is rising higher and higher not because it’s hard to discover or diagnose but the early stages of oral cancer are going unnoticed (“Oral Cancer Facts” 2014). More often than not, treatment is being sought out after it is too late. Understanding the causing factors of this disease and taking the proper…

The CT scanner Depends upon several steps:- 1-The x-ray tube and detector transverse (scan) the object. 2-The radiation beam passes through the object and is attenuated. The intensity of radiation beam from x- ray tube and transmitted beam both are detected by suitable detectors. 3-The transmitted beam and the references beam are both converted into electric signals. 4-These output current signals are then converted into digital form by analog –to-digital converter. 5-The digital data are…

created when a component is attacked with high energy electron. So when a high energy electron attacks the target electron in an atom it, this leads to the target electron being ejected from the inner shell of the atom. Whereas bremsstrahlung radiation is when radiation is given off by a particle that is charged, usually an electron, because of acceleration which is caused by another charged particle, usually an atomic nucleus. The x ray beam from an x ray is modified to suit the needs The…

with radiation (Appendix 16) and instructions for collecting and shipping specimens for laboratory testing by urine bioassay (Appendix 17a for distribution outside VDH, Appendix 17b for distribution within VDH). For clinical management and care of patients with significant radiation exposure or contamination (≥ 1000 times background), DRH may refer healthcare providers, through the LHD Director, to REAC/TS. REAC/TS provides 24-hour clinical consultation for the medical management and radiation…

were done, which made this war one of the worst in history. On August 6th, 1945, Hiroshima became victim to the first atomic bomb deployed by The United States. The bomb immediately killed tens of thousands of people; many more would later die of radiation exposure. Three days later a second deployed bomb was dropped on Nagasaki killing an estimated, forty thousand people. With these bombings, thousands of civilians were, brutally without warning, killed in an attempt to end the war. A new…

Authors Delfino and Day explain the risks to radiation exposure. “ [Eric J.] Hall and [Li-Jun] Wu of the Columbia University College of Physicians and Surgeons and others point out that the very nature of IMRT necessitates a longer radiation time, a larger volume of non-malignant tissue exposed to radiation, and an increase in total exposure—all of which nearly double the risk of radiation-induced secondary cancers with post-exposure lifetime....”(3). This shows how…

Electromagnetic waves are a type of radiation that is produced from electrons (negatively charged particles) and x-rays is a type of electromagnetic wave. The shorter the wavelength of a wave, the more energy the wave emits. Gamma radiation has the shortest wavelength amongst all the other electromagnetic waves and has the most energy. It cannot be seen or felt and can pass through almost anything. X-rays have slightly longer wavelengths than Gamma rays and has the second most energy emission.…

Stage 3 means the cancer is in more than one lobe of the lung or it has spread to lymph nodes or nearby areas in the chest. The patient may have surgery if the surgeon can remove all of the cancer or they are well enough. This may require having to remove part or the whole of the lung. After surgery, they might have chemotherapy to lower the chance of the cancer coming back. If they cannot have surgery they might have one or more of these treatments radiotherapy, chemotherapy or…

is that a nuclear bomb is designed to destroy organisms using heat and impact, while a dirty bomb is designed to kill with gamma radiation. Radiation from dirty bombs, besides burning through skin, also alters the DNA in bone marrows, which significantly weakens the body’s immune system, and turns some cells into cancer cells. Though nuclear bombs also emit some radiation, it is not intentional that that occurs. 2. Summarize the life and work of Henry Moseley. (3 marks) Throughout his life,…
