There are many uses for radioactive substances. In the medical world, there are a number of health care processes that make use of the properties of the nucleus. This is also known as Nuclear medicine ("Nuclear Medicine").
In this essay, we will be looking at a particular nuclear medical treatment; we will be looking at radiotherapy. Radiation therapy usually refers to the ionizing radiation. Ionizing radiation is mostly used in oncology, but it can be used for other purposes such as ionizing an overactive thyroid. The radiotherapy allows the hindering of fast reproduction of cancer cells ("Radiation Therapy").
There are two ways of using radioactive therapy. One is to undergo the therapy from outside the body using radiation from radioactive

In fact, about 40 percent of people who are diagnosed with cancer undergo radiation therapy ("Uses of Radiation"). Additionally, it has been used to successfully treat patients for over a 100 years and during this time period the process has obviously been refined to be as safe as possible. When receiving radiotherapy, the oncology team will ensure that there is a clear plan that certifies that no fragile organs are affected by the process. However, there is a risk that the treatment will result in the development of a second cancer ("Understanding Radiation …show more content…
And, there is high possibility that there will be a new cancer that will develop later in the patient’s life, so it may solve one problem and then cause another one. Additionally, there are high risks of having side effects. The radiotherapy could affect important organs. There are ways to avoid this with modern techniques but the radiotherapy team can only reduce the risk, not eliminate it. But, the side effects are better than alternative treatments such as chemotherapy. Another point that should be considered when choosing this treatment is that relatives might be affected from the fact that the patient might be radioactive. In fact, right after the treatment the relatives cannot spend more than a few hours in order to avoid health issues. Finally, if it is an advanced cancer, the patient might be required to stay at the
According to Helibron and Seidel (2011) nuclear medicine began as a simple experiment in the early twentieth century by George de Hevesy. De Hevesy started the experiment by deciding to test the effects of radiation on living things, beginning with bean plants, then onto furred animals, and then continued onto finding the effects of radiation on the human body, when he did this he became the first person to ever use radiation on a human being. He along with his partner E. Hofer, in 1931, consumed Deuterium which they had diluted with tea and found that traces of radioactivity stayed within their bodies for between eight to eighteen days. This was the first known use of radiation on humans (p. 1). This was just the beginning though, as time moved on the use of nuclear energy advanced and as it advanced it began to bleed into more subjects than those that it had been used in before, such as, nuclear medicine. Although it has its drawbacks, such as nuclear waste, there are many different benefits to nuclear medicine. Examples of such would be advances in therapy and treatment of disease...
The role of the radiologist is one that has undergone numerous changes over the years and continues to evolve a rapid pace. Radiologists specialize in the diagnoses of disease through obtaining and interpreting medical images. There are a number of different devices and procedures at the disposal of a radiologist to aid him or her in these diagnoses’. Some images are obtained by using x-ray or other radioactive substances, others through the use of sound waves and the body’s natural magnetism. Another sector of radiology focuses on the treatment of certain diseases using radiation (RSNA). Due to vast clinical work and correlated studies, the radiologist may additionally sub-specialize in various areas. Some of these sub-specialties include breast imaging, cardiovascular, Computed Tomography (CT), diagnostic radiology, emergency, gastrointestinal, genitourinary, Magnetic Resonance Imaging (MRI), musculoskeletal, neuroradiology, nuclear medicine, pediatric radiology, radiobiology, and Ultrasound (Schenter). After spending a vast amount of time on research and going to internship at the hospital, I have come to realize that my passion in science has greatly intensified. Furthermore, both experiences helped to shape up my future goals more prominently than before, which is coupled with the fact that I have now established a profound interest in radiology, or rather nuclear medicine.
2. External Beam Radiation Therapy (EBRT) which is usually offered when the lung cancer is either considered to be primary, or when it has metastasized (spread to other organs). This form of treatment uses a linear accelerator machine to focus a precise beam of radiation on a given area of the body for a precise period of time to kill off cancerous cells.
At this day in age we are constantly trying to improve the field of medicine in any way that we possibly can. We cherish every birthday and continually try to prolong life. Not only through every field of medicine, especially in terms of cancer. The American Cancer Society is “the official sponsor of birthdays” and is making leaps and bounds in the types of care that cancer patients receive. One of these many breakthroughs is the practice of Stereotactic (Body) Radiotherapy or S(B)RT. SBRT and other radiation therapies have the ability to greatly improve the way that we treat the issue of cancer and the variation of treatment options; however, they have raised the concerns of long term effects from radiation and cost-effectiveness. As research has begun to show, radiation therapies are having great success in curing cancer.
...atment is safe because radio-iodine is able to deliver a sufficient amount of radiation to the thyroid allowing to slow the hormone production, and only deliver a small amount to the body. The radiation delivered to the body is far from harmful and is only equivalent to the amount of radiation delivered from two routine diagnostic X-Ray procedures such as a gastrointestinal series ("Educational Material"). The form of treatment has been used for 35 years and over one million patients in the United States have been assisted through the treatment of radioactive iodine ablation. Most physicians will rely on this treatment and recommend 90 percent of their over active thyroid patients to receive the radioactive iodine ("Educational Material"). The treatment, till this day, is known to continuously alleviate the majority of symptoms hyperthyroidism patients have today.

by using collimation it causes the patient dose of radiation to decrease. The reason the radiation
Radiation therapy is a complex treatment plan to treat cancer in patients. Its treatment can be used alone or in conjunction with surgery or chemotherapy. Radiation therapy is delivered by a team of individuals who specialize in the treatment of cancer. There are several ways in which the radiation can be delivered to the patient with specialized equipment. Radiation therapy is an exciting field of study that can be beneficial to patients who are affected by cancer.
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...

Nuclear Medicine is the use of radioisotopes for diagnosis, treatment, and research. Radioactive chemical tracers emit gamma rays which provides diagnostic information about a person's anatomy and the functioning of specific organs. Radioisotopes are also utilizes in treatments of diseases such as cancer. It is estimated that approximately one in two people in Western countries are likely to experience the benefits of nuclear medicine in their lifetime.
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.
Conventional radiation therapy: This type of radiation therapy is usually given every weekday over a period of four to six weeks. One may not realize the full effect of conventional radiation therapy for 10 or more years after treatment.
One of the greatest events of twentieth century was the use of radioisotope as a source of energy and as medical and industrial tools. Using radioactivity has been a global issue owing to its very nature. When it is used for peaceful purposes, it is a triumph of science because it can solve energy problems in the form of nuclear energy but the side effects in the form of harmful radiation and harmful radioactive waste is the real limitations of science. This essay will attempt to analyze the application of science in the use of radioactivity and radioactive isotopes and how science is not so effective in dealing with the side effects.
