Ionizing radiation

a long time, surgical removal was the standard of care, independently of the size, location or histology. However, due to the anatomical limitations, neurosurgical intervention may bear the risk of significant side effects. Over the last decade radiation therapy (RT) has become a valid treatment alternative for the treatment of meningiomas. Especially with the advent of high precision techniques, such as stereotactic radiotherapy or intensity modulated radiotherapy (IMRT). Local dose deposition…

Spectroscopy is the study of objects, which is represented on the spectrum of color they radiate. An interaction of electromagnetic radiation with matter. Spectroscopy involves the process of absorption, emission, or scattering of electromagnetic radiation by either ions, atoms, or molecules. The process of absorption involves when light is absorbed by electrons that jump to higher energy levels. On the other hand, emission spectra are established when the electrons from high energy levels give…

The Life Of Richard Pryor Who was Richard Pryor, some people might ask? Well he is an African American Actor/ Comedian. One of his most famous quotes is ‘If I thought about it, I could be bitter, but I don't feel like being bitter. Being bitter makes you immobile, and there's too much that I still want to do. Richard Pryor is known for his colorful language during his live comedy shows , and he is highly influential , and always controversial towards African Americans. He has also been…

Colon cancer and rectal cancer is considered a disease developed in the tissues of the lower part of the gastrointestinal system. It typically starts in the inner lining of the large intestine as an uncontrolled growth of tissue called polyps. Together they are referred to as Colorectal Cancer. Colon cancer or bowl cancer originates in the terminal part of the large intestine whereas rectal cancer originates in the rectum which is the last portion of the large intestine to the anus. They are…

The National Institutes of Health has a printed consensus statement that clearly notes that the ideal treatment for these problems is total removal of the tumor. But there are other options including incomplete removal or stereotactic radiation therapy. Depending on the type of surgery done if the whole tumor is completely removed then the likelihood of it growing back decreases, but there can still be some down fall based on the type of surgery done. Some down falls include complete loss of…

works to fight cancer is radiation therapy. Radiation therapy is more effective than non-traditional treatments because it kills cancer for the better, even though it is a little at a time, after therapy in a few weeks or months. Yet it still kills cancer at hand rather than not at all. Depending on how much radiation a doctor uses on a patient, depends on if the cancer cells die and the patient is free of cancer. It all depends on the doses given, “At high doses, radiation kills cancer cells or…

Discussion and Scientific Explanations Colors help most people describe what different objects look like. When white light hits an object, in most cases, the object will absorb all of the wavelengths, except for one group. This group of wavelengths is then reflected off of the objects. The cones and rods in our eyes will then pick up this wavelengths and then the brain sees them as “color”. The reason that solutions have colors is because electrons in the chemical’s 4d orbital are jumping…

Reducing Patient-related barriers to pain management Intro Pain is one of the most common symptoms of cancer, and one of the most challenging subjects for health professionals including Radiation Therapists to address when treating patients. It is important to recognise that pain is ‘an intensely personal experience with biological, psychological and social components’, which is entirely subjective to the person who experiences it. Despite the development of “novel analgesics and updated pain…

The purpose of this spectroscopy, atomic spectra, and light lab was to further your understanding of how different gases are given specific wavelengths based on the variety of color that their light gives off. (Grossie, 285). Every ion gives off a different light configuration based on the amount of energy they hold. (Grossie, 285). A spectroscope is used to break down the light given off by the gas into different colored lines in different areas on the scope. The measure of these lines is what…

problem with radiation is that both normal and cancerous cell are killed. The people who administer the radiation carefully control the doses so the normal cells have a chance to recover while cancerous cells do not recover from the assault. Radiation causes side-effecting such as scarring the tissue of normal cells, but it also tries to destroy remaining cancer cells. The radiation team uses X-rays and CT scans to help target the area where the radiation is needed. The radiation oncologist…
