The Ethical Use Of Radioisotopes In Nuclear Medicine
Radioisotopes in Medicine
Nuclear medicine uses radiation to provide diagnostic information about the functioning of a person's specific organs, or to treat them. Diagnostic procedures are now routine. * Radiotherapy can be used to treat some medical conditions, especially cancer, using radiation to weaken or destroy particular targeted cells. * Tens of millions of nuclear medicine procedures are performed each year, and demand for radioisotopes is increasing rapidly.
Nuclear Medicine
This is a branch of medicine that uses radiation to provide information about the functioning of a person's specific organs or to treat disease. In most cases, the information is used by physicians to make a quick, accurate diagnosis of the patient's

The most common radioisotope used in diagnosis is technetium-99, with some 30 million procedures per year, accounting for 80% of all nuclear medicine procedures worldwide.
In developed countries (26% of world population) the frequency of diagnostic nuclear medicine is 1.9% per year, and the frequency of therapy with radioisotopes is about one tenth of this. In the USA there are some 18 million nuclear medicine procedures per year among 311 million people, and in Europe about 10 million among 500 million people. In Australia there are about 560,000 per year among 21 million people, 470,000 of these using reactor isotopes. The use of radiopharmaceuticals in diagnosis is growing at over 10% per year.
Nuclear medicine was developed in the 1950s by physicians with an endocrine emphasis, initially using iodine-131 to diagnose and then treat thyroid disease. In recent years specialists have also come from radiology, as dual CT/PET procedures have become

Only ten percent of medically used radioactive isotopes used in America are actually produced here in the United States. The other 90 percent we use must be imported from other countries, creating a hardship on our medical community who desire to meet growing demand--as well as participate in research activities that might aid in further advances in this field (for both cancers and other disease treatments).
Additional benefit * Another benefit of radioactive isotopes is its ability to aid doctors in making an earlier and a more thorough diagnosis of cancer. When a tiny amount of the radioactive substance is introduced in some way into the patient's body, it can be detected by a special machine (through the energy it gives off) as it travels through the body. This allows the doctor to track the movement and final location of the isotope, more accurately pinpointing the exact area infected than with the x-ray methods used before.

    Radioisotopes allow treatment and diagnosis of medical illnesses without the cost and trauma of open surgery (which carries risks like infection, accidents, and long recovery periods). The use of Tc-99m produces hot-spot images, which reveal early signs of disease and map how organs are functioning. The low energy gamma radiation it emits, the small dose in which it's injected and it a short half-life (6hours), minimises damage to tissues. The patient's total exposure to radiation is less than in an X-ray. So far, there have been no reported side effects.…

    Radiation consists of using high doses of radiation to kill the cancer cells. What radiation does to the cancer cell is that it causes chemical changes that destabilize DNA, the genetic code that tells a cell how to grow, reproduce and die. Doctors need to be extra careful with radiation because it can also kill good healthy cells. To protect good cells from getting harmed, doctors need to be as precise as possible when aiming radiation. Doctors also limit the amount of radiation administered in a patient, depending on the goal of treatment and the organs around the area that is to be treated, (Bernard, 2006).…

    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.…

    Radiology is a medical specialty that employs the use of imaging to both diagnose and treat disease visualized within the human body. Radiologists use an array of imaging technologies (such as x-ray radiography, ultrasound, computed tomography (CT), nuclear medicine, positron emission tomography (PET) and magnetic resonance imaging (MRI)) to diagnose or treat diseases. Interventional radiology is the performance of, usually minimally invasive, medical procedures with the guidance of imaging technologies. The acquisition of medical imaging is usually carried out by the radiographer or radiologic technologist. The field of radiology is rapidly expanding due to advances in computer technology, which is closely linked to modern imaging.…

    Nuclear chemistry in medicine is very controversial. Many say the dangers of using radioactive materials on human bodies are far more negative than positive. Others strongly agree with the use of radiochemistry in the field of medicine. Nuclear medicine is in the field of medicine by using imaging devices. Doctors use small amounts of radioactive materials called radio tracers that are either injected into the bloodstream, inhaled or swallowed. Radiation therapy is also a therapy that uses radioactive materials to treat cancers. The use of nuclear medicine is a fast-growing idea in the world of medicine. About 1/3 of modern procedures in hospitals use nuclear chemistry. Nuclear medicine technologist’s employment is projected to grow faster than the average for all…

    Brief Description The independent community pharmacy owner is a hybridized role that emphasizes pharmacist management skills in a community setting. The individual is responsible for both providing care to the community and for maintaining the stability of the business itself. It is necessary for the owner to be capable of leading a team, often less than 10 persons but can increase with store growth, and have accounting skills. The owner, generally, has a large sum of money invested in the pharmacy and as such their financial stability is intertwined to the success of the nuclear pharmacy. A typical day may include tasks such as handling radioactive substance, handling conflicts between staff members, filling nuclear prescriptions, ensuring the proper handling of radiopharmaceuticals, and communicating the proper radiopharmaceutical-related information to others. The biggest challenged for persons considering a career in this area are the time and money that must be invested to initially start a nuclear pharmacy. Equipment used in a nuclear pharmacy tends to be more expensive. Tungsten shields and leaded glass shielding are some of the more expensive items found in a nuclear pharmacy. About three quarters of a million dollars needs to be invested in inventory, and for a new graduate, that is a large sum of money. Nuclear pharmacy owners spend a great amount of their time in work-related activities, and 80 hour work weeks are not uncommon. The stress level that comes with the added responsibility of running the business can be taxing. It may take many years before the pharmacy is profitable, and it is entirely possible the store will never become profitable. One must consider all of these possibilities before deciding upon a career as an…
