Radiation is something that we are exposed to on a daily basis; it is in the air we breathe. Radiation is used in hospitals, research labs, and in many medical procedures. It is also commonly used as a treatment for cancer. In some cases it helps and in others it does not. Radiation is used for cancer treatment because it kills cells. The issue is that it is killing healthy cells at the same time it is killing cancerous cells. Even though medical imaging emits radiation, it makes it possible for us to detect injuries and significant diseases. Radiation is measured in a few different ways, and has numerous side effects on our body depending on the dosage. We are exposed to it in the environment unintentionally, and at times in treatment purposely. Additionally, there is current research in effort to reduce the amount of radiation in medical procedures. We must first understand what radiation is. Radiation is when excess energy is released. This process happens when unstable atoms become stable. This happens to radioactive materials. There are three common types of radiation emissions. They are alpha particles, beta particles, and Gamma rays. Alpha particles can be dangerous if they are inhaled or ingested. They can also enter your body through a cut, but it cannot bypass human skin. Beta particles can be very dangerous to your health if they are ingested, inhaled, or if it enters through a cut. It is important to know that it can at times enter through your skin, unlike alpha particles. In most cases, it is best to have a thicker layer covering your skin so that you’re positive it does not go through your skin. The most severe type of radiation emission is through Gamma rays. Like the other two, it can cause severe damage if it i... ... middle of paper ... ...reduce radiation exposure to their patients. The first thing is that they will only schedule an imaging exam if completely necessary. Second, they are focusing on dose optimization. Third, they are reducing their patient’s dosage to as low as possible (Shrestha). Radiation is all around us and exposure to it is inevitable. Some of the exposure, such as in the environment, is unintentional. We are also purposely exposed to it in medical imaging. As stated above, there are many positive and negative sides to radiation. Medical imaging has grown tremendously over the years and allows us to detect injuries, and diseases. The negative side to radiation, is all of the dangerous health effects that can harm our body. There is a lot of research that scientists are working on to reduce the amount of radiation that our bodies are exposed to when undergoing medical imaging.
Radiation exposure can affect children as well an children have the risk of being the most harmfully effected by radiation because their body absorbs substances differently also their bodies can or are more likely to get certain kinds of cancers from too much exposure, “they are also closer to the ground, where radioactive fallouts settle.”
The conversation around the rising costs of health care continues to be a high priority topic of discussion from consumer all the way up to the government. There are many products and services that contribute to the rising costs, as well as some responsibility left to practicing providers who choose to use high dollar radiology services for patient care. Ionizing radiation has been used for more than a century, however, this evolution or radiology services into widespread diagnostic and therapeutic uses has resulted in a significant increase in the population’s overall exposure to radiation with the potential to increase the risk of cancer (Amis & Butler, 2010). Examples of high dollar radiology services are services like Magnetic Resonance Imaging (MRI), Computer Tomography (CT) scans, and Echocardiograms. These services allow physicians t...
Since the beginning of the propitious world, the core aspect that keeps it thriving is the propensity for people to discover innovations; however, progress of the past is, systematically, detrimental to the future. Not long after the revolutionary invention of the X-ray in the late 19th Century, an unprecedented number of medical examiners noticed (unknown to the time) radiation burns all over their body; decades later, an extraordinary surge in cancer cases had arisen. Perhaps, during the course of these years, scientists and researchers desired to further progress the x-ray (into the immense subsidiaries that are here today), and disregarded any flaws in the apparatus. This systematic inclination continues into the present time as Gary Marshall and Shane Keene notes in their 2007 article, “New technologies allow for patients to be overexposed routinely, and also allow for repeats to be taken quickly, making it easier for a technologist to multiply the patients dose without considering the implications” (5). The gaffes of radiology are present not only in the diagnostic setting, but also in the surgical and therapeutic areas. Working with radiation, it is imperative that the staff is aware of mistakes that are potentially fatal not only for patients, but themselves. It is especially important for medical radiologists to be cognizant of pediatric patients. The standard practice of pediatric radiology in the United States is to follow the step-by step formula from which adult patients are treated and diagnosed. There are copious consequences for following this technique since a child naturally has less body mass and a weaker immune and lymphatic system to manage radiation and its adverse effects. Medical radiology, being a...
There are essentially three main types of cancer treatments; surgery, chemotherapy, and radiation. Surgery allows doctors to effectively remove tumors from a clear plane. Chemotherapy uses drugs to treat the tumor; but often the drugs affect other healthy cells in the process. Using radiation as a treatment can be either precise or vague. Many health stigmas can come from the vague forms of radiation or conventional radiation therapy. Conventional radiation treats both the unhealthy and healthy cells, therefore exposing healthy cells to harmful radiation (Radiation Oncology, 2011, p.6). When healthy cells are exposed to gamma radiation they are also exposed to ionizing radiation. The ionization can cause “breakage of chemical bonds or oxidization (addition of oxygen atoms)” in a cell; the main impact of this is on a cell’s DNA, if two strands of DNA break it can result in “mutations, chromosome aberrations, ...
Modern medicine is capable of treating a tremendous range of human disease and injuries, but the usefulness of all medical specialties depends on accurate diagnosis. Virtually every conceivable medical specialty relies on radiological technologies to provide formal diagnoses, making radiology one of the most important of all medical specialties. Radiologists enjoy some of the best working conditions in modern medicine and typically experience very positive employment conditions. Consequently, their services are generally in very high demand, with many starting out with six-figure annual incomes immediately after completion of their professional training.
“External radiation uses a machine that directs high-energy rays from outside the body into the tumor and some normal nearby tissue.” (American Cancer Society p. 5) After this treatment the patient will not be radioactive, but treatment is delivered in small doses and can last several weeks. “Internal radiation or brachytherapy, uses a radioactive source, called an implant, that’s put inside the body in or near the tumor.” (American Cancer Society p. 9) It may be placed in an organ or in the cancerous tumor. The patient will be radioactive for a short time. Due to the implant being near the source of cancer a larger dose can be delivered to the patient. “Systemic radiation uses radioactive drugs to treat certain type of cancer.” (American Cancer Society p. 12) The drugs used are called radiopharmaceuticals and can be delivered orally or intravenously. “They collect where the cancer is to give off their radiation and kill the cancer cells.” (American Cancer Society p. 12) After this treatment the patient will be radioactive, and will take a few days to be removed from the patients
For decades, the effects of radiation has been studied by doctors around the world. X-rays are used in the medical and dental field to take radiographs of certain parts of a person's body. Some have become concerned of the long term and short term effects of having x-rays taken because of the radiation that is exposed. Since the rise of concern, studies have been done to find any type of link between cancer and radiation from x-rays. Specifically, in dental x-rays, researchers have been performing studies trying to prove that radiation from x-rays in the dental office can cause cancer .
What is radiology? Radiology is a branch of medical science that makes the use of radiation and radioactive materials. Radiology is related to energy- related physical phenomena in the diagnosis and treatment of particular diseases. Two major therapy- related areas of radiology are so- called therapeutic radiology. Therapeutic radiology deals particularly with the use of ionizing radiation is to treat cancer, and interventional radiology, Which radiological imaging techniques are used to assist various minimally invasive surgical procedures.
Computed tomography (CT) and Radionuclide imaging (RNI) are both a form of diagnostic imaging. Since they have been first introduced in medical imaging they both suffered a huge development over the years in terms of image acquisition and also patient radiation protection. The following essay it is going to focus on just a few important things that make CT and RNI similar and different in the same time. However this subject can be discussed in much depth, the focus is going to be on the similarities and differences of the physics imaging methods and also a small awareness of biological effects and radiation protection.
Radiation therapists work closely with patients to fight cancer. According to Health Care Careers, Oncologists, Dosimetrists and nurses are some of the professionals that a radiation therapist works with while caring for a cancer patient. This group of professionals will determine a specialized treatment plan. The first step usually includes a CT scan performed by a radiologist to find the exact area that needs to be targeted with x-rays. Next, the therapist uses a special machine that emits radiation called a Linear Accelerator. They use this machine during a treatment called external beam therapy. During this process, the Linear Accelerator will project x-rays at targeted cancer cells or tumors. Another therapist will be in a different room monitoring the patient’s viral signs until the procedure is over. The external therapy l...
...b done but can bring more side effects to the patient. Radiation is a connection to physics, which was a very important important discovery in science because it has cured many patients who have been affected by cancer when before they were left to die. Radiation therapy, like any other way exposed to radiation, can be a risk. The importance of undergoing this treatment is to see the positive side of it, not just think of the bad things that can come out of the radiation therapy. There is a risk of second cancers but isn’t it worth it? This treatment gives patients the chance to live a longer and normal life, this wasn’t an option before, so it’s important to be thankful for being born in this time period. Radiation might not be seen as a good thing in many occasions but it is now used for the good of the people affected by cancer, it’s a second chance for life.
...why does the technologist step behind a shield to prevent exposure to themself?" The radiation dose for each exam is relatively small, but over time, the dose can add up. There are many state and federal regulations limiting the total radiation dose that may be received by people working with radiation. To comply with those regulations, the technologist must follow strict precautions to keep their cumulative exposure to a minimum.
A radioisotope is an isotope that emits radiation as it has nuclear instability(Prostate Cancer; Fusion imaging helps target greater doses of radiation).Those who are not too familiar with radioisotopes may think their use is for harmful radiation, nuclear weapons, and the possibility of turning into a giant, raging, green monster. However, there are much more positive uses for radioisotopes. There have been many medical advances thanks to the benefit and practice of radioisotopes in nuclear medicine. These advances have been able to diagnose and treat a variety of diseases.
Radiation is one of the most dangerous and easiest way of having health effects. Radiation was first discovered by Roentgen. Hazards are the first things people need to know in order to understand what it can do to your body. It causes many health effects on everyone out in the world. It harms people in the dentistry and field and even in the medical field. Normal people out the world can also be exposed when coming into one of these offices and getting x-rays of some type.
Heat and x-rays are an example of radiation. A type of non-ionizing radiation is radiofrequency radiation. (Cancer 1) If radiofrequency radiation is engrossed in large amounts of materials containing water and food it can produce heat. This can lead to burns, tissue damage, and harm DNA cells. Heat is the main effect of exposure to radiofrequency. (Cancer 2)
