The Atomic Bomb Lighting the Way for Radiation Protection Even though radiation has been around since the beginning of time there was little known about it. When x-rays were discovered in 1895, radiation research followed suit right after. With Germany under Hitler’s reign, the Nazis began separating uranium to form the first atomic bomb to control the world. The push for the United States to be the first with the atomic bomb began with this knowledge. With the help of several scientists…

There are possible connections to death when receiving radiation therapy for patients that have cancer. Radiation therapy is also known as radiation oncology. Radiation is a form of energy that happens naturally, it can be controlled to use more intentionally. Radiation is a tool for medical treatment, radiation therapy is the most common type of treatment used for cancer. Radiation can be given as a curative modality, either alone or in combination with surgery and/or chemotherapy. Breast…

3.6 Management 3.61 Treatment Oral cancer is a localised disease that most likely infiltrates adjacent bone and soft tissue and tends to spread to regional lymph nodes in the head and neck region. It is essential to carry out a thorough examination which includes, inspection, palpation of oral cavity and neck; distant metastasis is quite unlikely. Imaging modalities such as CT and MRI are commonly used to investigate the extent of spread of oral cancer to adjacent tissues including bone and…

Figure 5.8 is a pulse height spectrum of the net counts of the beta- emitting radionuclide, 137Cs as a function of pulse height voltage. Within Figure 5.8, the majority of the counts reside in the low voltage region, below 25 mV. It is possible to discriminate the between the different particle types by virtue of the pulse height distribution and establishing detection window threshold within the detection unit. As discussed earlier, it is possible to establish a lower threshold limit that…

Radiology is the science of utilizing varying forms of high-energy radiation such as x-rays, for the diagnosis of injury and disease. An x-ray technologist is the medical professional responsible for the x-ray procedure. The technologist has many roles and is obligated to follow protocol while completing daily responsibilities. One of the main roles of the technician is communicating with the patient, this involves but is not limited to: greeting the patient, educating the patient on the…

leading forms of treatment uses radiation to target the genetic material within those cancerous cells. Radiation therapy uses high energy beams, such as x-rays, gamma rays and charged particles, to damage the DNA to the extent where the cell will either die or stop dividing (“Radiation…

Interpretation of the NOESY: (Nuclear Overhauser Effect) spectrum of 1-(2-methyl-1,2,3,4-tetrahydroquinolin-4-yl)azepan-2-one (3a) is as follows. Strong coupling interaction of protons of 2nd and 4th position in 1-(2-methyl-1,2,3,4-tetrahydroquinolin-4-yl)azepan-2-one (3a), was not so strongly observed in COSY because it involves long range coupling i.e. protons attached between 2nd and 4th carbon atom. Hence, we studied NOESY to know the spacial interaction between these two protons. Thus, the…

Lasik surgery is the most common type of refractive surgery. The aimed result of the surgery is to refract light rays on the retina without damaging the surrounding cellular cells. Lasik surgery is a procedure that was developed to correct the vision problems of Nearsightedness, Long-sightedness and Astigmatism. Nearsightedness (myopia) is when you can see nearby objects clearly, but distant objects seem blurry. Long-sightedness (hyperopia) is when you can see distant objects clearly, but nearby…

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…

Knowing how it works, and what your going to expect calms most peoples fears. Chemotherapy gives the patients a feeling of control over their Cancer. Radiation therapy is using high-energy particles to destroy or damage the Cancer cells. Radiation therapy is the most common Cancer treatment. It can be used by itself to with other treatment types. Hyperthermia is using heat to treat the Cancer. This method has been used for a long time but never…
