Interview: 2004? In 1977, Dr. Rosalyn Yalow became a co-winner for the Nobel Prize in Physiology

The radioactive form of an element acts in the same way the nonradioactive form does. When a person ingests iodine it concentrates in the thyroid gland whether it is in a radioactive or nonradioactive

Majority of radioactive elements can be positively used, for example, curium and uranium. These particular elements are used for science or medical research and also help detecting cancer in patients. Radionuclides are also used to directly treat illnesses, such as radioactive iodine, which is taken up almost exclusively by the thyroid, to treat hyperthyroidism. Elements like promethium can be used in nuclear batteries for guided missiles,

This radioisotope is employed in medicine to monitor thyroid gland functioning to treat goitre, thyroid cancer, locate tumours of the brain and liver. Iodine-131 is used in investigations to trace the course of compounds in metabolism. Several iodine compounds are used as contrast mediums

Rosalyn Sussman Yalow graduated Hunter College as the first women to graduate in physics (Bauman et. al. 2011). She also led a way for acceptance and understanding of women’s role in science in America (Bauman et. al. 2011). She even inspired Mildred Dresselhous, who was a professor at Massachusetts Institute of Technology (MIT) and president and officer of many Associations including American Association for the Advancement of Science, to pursue the career she wanted (Bauman et. al. 2011). Rosalyn born to Clara and Simon Sussman in New York City, on July 19, 1921 (Brody 1996). She married Aaron Yalow on June 6, 1943 and had two children named Elanna and Benjamin (Brody 1996). In 1977, Dr. Yalow won the Nobel Prize in medicine and was

Rosalyn Yalow was a very successful and hard working woman. Rosalyn was a science that known around the world for her revolutionary and life changing design of the radioimmunoassay but better known as the RIA. She did many things and overcame many obstacles in her life. She was one of the first woman to win the Nobel Prize for medicine. Rosalyn Yalow helped many people with her accomplishments and will help many in the future.

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

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.

Seidlin reported on the success of radioactive iodine (I-131) in treating a patient with advanced thyroid cancer. Later, the use of I-131 was expanded to applications such as thyroid gland imaging, hyperthyroidism treatment and quantification of thyroid function. By the 1950s, the clinical use of nuclear medicine had become widespread as researchers increased their understanding of detecting radioactivity and using radionuclides to monitor biochemical processes.” (Dr. Ananya Mandal, MD) With this information, we know that nuclear medicine is successful with multiple cases of diseases. Our technology today has improved on how treatments can be done. Nuclear medicine has improved from the time being. If treating a disease with nuclear medicine back then had been successful, imagine all of the success stories of everyone today who has had the chance of using nuclear medicine. Nowadays, the science and technology has developed so much that it is easy to cure any type of disease when proper guidance is given. If the technology is used properly, the side effects can be reversed. Today, we can easily figure out a way to reverse the effects of what we did to ourselves with all of the equipment, tools, and technology that people

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.

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

The most commonly used radio tracer for thyroid imaging are TC99m(pertechnetate) , iodine-123 and iodine-131. Thyroid evaluation is one of the most frequently performed nuclear medicine procedure.The equipment use to test for the radioactivity is the gamma probe and is the only device used to test for graves disease. (*3)This device is a handheld device with a Geiger-muller tube, or or scintillation counter, for intraoperative use following interstitial injection of a radionuclide, to locate regional lymph nodes by their radioactivity It is used primarily for sentinel lymph node mapping and parathyroid surgery. The Gamma Probe is also used for RSL (Radioactive Seed Localization), to locate small and non-palpable breast lesions. The sentinel node market experienced high growth in the early and mid 90's starting with melanoma sentinel node surgical search and breast cancer sentinel node staging; both are currently considered standards of care. Most surgeons propose node staging after a positive breast biopsy. New applications are being developed for parathyroid direct detection and intra-operative detection of cancerous tissue using tumor-seeking radiopharmaceuticals. Parathyroid detection is growing fast, while the intraoperative use of gamma probes for direct tumor detection is just emerging. Canberra is one of the manufactures of a gamma probe also know as a GP series- Geiger muller detractors A gamma probe is A pair of rugged halogen-quenched GM detectors serves as the basic detection elements in the GP Series detectors used for wide range gamma radiation measurement. The way this device works is the signal from the gamma probe with Geiger-muller tube and the voltage power supply go to the preamplifier to another amplifier and threshold control. This signal is split one side goes to the rate meter and audio circuit, the other signal goes to the scaler and display driver circuitry which is

Irene Joliot-Curie has been awarded with the Nobel Prize for chemistry, her and her husband Frederic Joliot-Curie for their discovery of artificial radioactivity. Her most significant achievement is uncovering how to synthesize radioactive elements.

At this time, it is not clear how much diagnostic radiation is contributing to the increase in thyroid cancer cases. It is possible that the increase in the diagnosis of thyroid cancer can be attributed to a greater rate of detection by use of ultrasonography and fine needle aspiration3. The thyroid tissue itself is among the tissues that are less sensitive to radiation, however, thyroid cancer is still such a concern because the thyroid is so superficial in the body1 (77). “Even doses as small as 50–100 mGy have been associated with an increased risk of thyroid malignancy in children, with a

Radioactivity has been around since the 1800s. It is very popular in the medical field. It is used my many professionals to help diagnose and treat people every single day. Although it does have some advantages and disadvantages, people still use it to this day.
