How Did Radioisotopes Change Our Life

People also benefit from atomic research in the medical field. Many people are aware of the wide use of radiation and radioisotopes in medicine. Nuclear medicine mostly uses radioisotopes which emit gamma rays from within the body. Estimates show that about one out of every three hospital patients benefits in some way from the use of nuclear medicine. Just think, every time you have an X-ray taken you are benefiting from nuclear research. Without X-rays, doctors would have a far greater time trying to set a broken bone if they even knew it was broken! Another common medical procedure that involves atomic research is the Cat-Scan. During this procedure the patient is injected with a radioactive isotope which shows the flow of blood through the

The problems with using radioactive isotopes are if they get cancerous and you are human or animal it could stop them having children depending where you have the cancer in your body Also if that does happen it’s is going to stop the human/animal cycle because you can’t have kids. If you have cancer and they can’t cure it you are going to die and that going to be upsetting for your

The origin of nuclear medicine can be traced all the way back to the invention of the cyclotron by the late great Dr. Ernest Orlando Lawrence. Lawrence, who died 1958, worked at the University of California at Berkeley. He, according to Jeffrey Kahn, he was basically just trying to make new atoms by combining them in an accelerator when his little brother John suggest they use the machine for medicine. John, who also attended Berkley, started by

During the last decade, major progress has been made in the treatment of disease with radioisotopes. Treatments involving the use of medical isotopes are gaining momentum in the race against many types of cancer. FDA approved and highly promising therapies are doubling every 3 to 4 years. Some researchers predict that over 80% of cancer types should be treatable with

Seaborg began working with one of the pioneers of nuclear medicine, Joe Hamilton, while attending Berkley. Hamilton needed a radioisotope that had a half-life long enough to be useful in dealing with in the human body; a half-life that was about a week. Seaborg and his long-time friend and partner, Jack Livingwood, used targets of tellurium and bombarded it with deuterons and some with neutrons to reveal iodine-131, which had a half-life of eight days. This element held major sentimental value to Seaborg due to its aid in his mother’s cure of hyperthyroidism. Iodine-131 is a major component still today in cancer treatment, particularly thyroid cancer. Seaborg and Livingwood also discovered cobalt-60, which is also a critical medical isotope. Cobalt-60 emits gamma radiation which in turn focuses directly on cancer cells to destroy it. “Hundreds of thousands of Americans have had their cancers treated by cobalt-60 irradiation, and it is also used to sterilize medical products and equipment” (36). Shortly

Being able to survive is the key to the existence of the Human race. In our endeavour to survive, we now need to tackle Cancer; the untamed monster of the modern era. Radioisotopes can be crucial to this survival. Very simply said; they can destroy any tumor. The isotopes are used as a source of a specific type of radiation, which is delivered to the target tissue by suitable means, destroying the tumor. The challenge in this kind of treatment would be not to destroy the organ itself in the bargain.

Imagine a world with no controversy or worry about nuclear energy. Sounds impossible, but not if we are brave enough to make the step of sourcing our helium-3 from the

The nuclear medicine technologist use radionuclides to diagnose and treat diseases. Radionuclides means unstable atoms that release radiation spontaneously and they are purified and compounded to form radiopharmaceuticals that prepare and administer by nuclear medicine technologist. These technologists are particularly specialized health care professional. The radioactive drugs appear higher or lower concentration in the abnormal area of the patient’s body than in the normal area.

Issue: In medicine, radioisotopes are bonded with chemical compounds to form radioactive tracers, which are then injected into the patient’s bloodstream. The radiation emitted by the tracers allows doctors to obtain images of organ systems, facilitating the early and accurate diagnosis of disease. However, to avoid radio- active contamination, care must be taken in the storage, use, and disposal of this material.

When the words “nuclear chemistry” come to mind, many mixed emotions surface. On one side, a picture of devastated cities that were flattened by a bomb capable of freezing the shadows of people on the streets comes to mind. And the other picture: harnessing exponential amounts of energy, saving lives, and defeating cancer once and for all. No matter what stance is taken, the Atomic Age has both turned people against each other, but also has provided grounds for defeating a disease that hits each and every one of us at home, and that disease is cancer. When weighing the pros and cons of the Atomic Age, the pros clearly outweigh the cons. This era has brought upon clean, reusable energy, medical advancements beyond our dreams, and a better understanding of invisible radiation.

After World War II the United States began mass-producing radioactive isotopes. These were shipped for the use of physicians and scientists. It provided physicians with new tools for the diagnoses and therapy of disease, specifically cancer. The radioactive isotopes were also used by scientists. It enabled molecular transformations to be traced by biologists. Radioactive isotopes were however undercut in the 1950s as the dangers of low-level radiation was

Important attributes of medical nuclear isotopes are their small half-lives. A half-life is the time it takes for half of a sample of an isotope to decay. Technetium—99, for example, has a six-hour half-life. Although short, this half-life allows enough time for testing. After this time period, the isotope will lose some of its radiation. The minute half-life allows very little time for any damage

It is also generated from the use of medical equipment that used radioactive isotopes. Pathological medical waste that has been contaminated with radioactive materials is treated first as radioactive waste rather than as infectious waste.

The use of radioactive elements in medicine is still growing to this day. Many oncologists use it to treat their patients who have cancer. Many cancer patients use this option. They use the radiation to kill off cancer cells. X-ray technicians or radiologists will also use it to administer x-rays to people who may have a broken bone, or need an MRI. The patient is injected with a radioactive material that helps the doctor be able to see inside the body better, whether it be with pictures or ultrasound. Radioactive material is defined as “material that contains radioactivity and thus emits ionizing radiation. It may be material that contains natural radioactivity from the environment or a material that may have been made radioactive.” (The Healthy Physics Society). This happens when someone needs a colonoscopy. They have to drink or are injected with this liquid that helps their organs and all other masses in the body be seen better by the radioactive materials.

Radiation has been an ever present ingredient in the evolution of life on the Earth. It is not something new, invented by the ingenuity of man in the technological age, it has always been there.
