Thermal radiation

treat brain tumours, and certain types of cancer through “radiation delivered from a tiny source implanted directly into or next to the tumour. These sources produce gamma-rays, which have the same effect on cancer cells as X-rays. This treatment reduces damage to surrounding healthy tissue, thereby limiting side effects” (Radiation oncology, sec. 1, par. 1). However, though small, there are risks attached to this certain type of radiation treatment, according to Dr Ananya Manda the immediate…

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…

Radiation therapy is used in the treatment of approximately 40% to 60% of patients who are diagnosed as having cancer.1,2 Radiation therapy uses ionizing radiation delivered by external beam therapy or radioisotopes with either a palliative or curative goal.1 These complex treatments are usually delivered daily during a period of five to seven weeks.1,2 Radiation therapy is recognized as a high-risk procedure because of the number of steps and staff involved.3 The radiation oncologist, medical…

treatment can be classified as radiation therapy. The radiation that specific isotopes give off are utilized for effecting cancer cells. First of all, what is radiation? Radiation is energy that is carried by waves of streams of particles. The energy from radiation damages the genes (DNA) in the cancer cells. The damage done to the cells prevent them from growing and dividing, and often cause them to die off. Nearby normal and healthy cells can also be affected by the radiation. However most…

be examined (through ultrasound, CT imaging, etc.) before treatment planning begins and before each treatment so that the geometry and positioning of the source to the intended target is precise and accurate. Each day before HDR treatment, the radiation therapist must utilize a departmental QA checklist. There are several components to this checklist. • Visual inspection of transfer tubes~ to make sure that the source will have a clear pathway and will not get stuck or move slowly to the…

Introduction Food irradiation has been called “today’s pasteurization,” as the safety and quality benefits it offers are similar to those of pasteurization for milk in the early 1900s. (Palmer). However, there have been pros and cons associated with this process, and its increased use has also increased the debates over its benefits and safety. Economic impact (Pros/Cons) Food irradiation could potentially have a huge positive impact of lowering the costs of food. One of the benefits is a…

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…
