Informative Speech On Radioisotopes

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

The iodine uptake with hyperthyroidism is greater than normal. This means that the body produces too much thyroid, meaning there is too much

Week 3 – LOM Assignment The thyroid is responsible for taking iodine and converting it into thyroid hormones which are released into the blood stream and transported throughout the body where they control metabolism.1 The thyroid is a vital part of the human body as every cell in the body depends on it for metabolic regulation. Too much or too little thyroid hormone secretion can result in hyperthyroidism or hypothyroidism. Hyperthyroidism is caused when the thyroid secretes too many thyroid hormones. Hyperthyroidism causes a rapid heart rate, elevated blood pressure and tremors. Other symptoms include increased nervousness, inability to concentrate, weakness, restlessness, difficulty sleeping, frequent bowel movements, weight loss and irregular

Doctors use Iodine-131. Iodine-131 can be used to treat someone with hyperthyroidism. It can also be used to treat thyroid cancer. It can also be used as a type of medical imaging.

We also get iodine from the food we eat. Iodine can become dangerous when we don't eat enough of it and too much. Iodine deficiency will slow down the thyroid function and cause it to swell up. Too much iodine can affect the whole body. Loss of weight and disturbed heartbeats can occur.Iodine minerals are very rare. Salt solutions often contain a little iodine and 0.3% of iodine can be contained in sodium and calcium nitrate deposits. It can also be extracted from seaweed.It can melt at 113.5°C and boil at 184°C. It dissolves only slightly in water, but other liquids can give it a higher solubility.One of the first commercial uses for Iodine was for Photography. It was used in a technique for producing images on a piece of metal. These images were called daguerreotypes. As well as photographic chemicals, iodine now has many more uses. Iodine salts are used in pharmaceuticals and disinfectants, printing inks and dyes and animal feed supplements. It is also used to make polarising filters for LCD displays.Iodine is also added in small amounts to table salt, to avoid iodine deficiency. The radioactive isotope (iodine 131) is sometimes used to treat cancerous thyroid

Iodine is an essential element for humans. We need a daily intake of about 0.1 milligrams of

Seaborg and John Livingood in 1938 at the University of California, Berkeley Radiation laboratory. The scientist discovered uses for its radioactive properties and by 1939 a paper had been published suggesting that there was a potential for its use in medical diagnostic. More research was conducted before 1946 when Iodine-131 was first used to treat thyroid cancer. Then eventually the isotope was used for detection of brain and liver tumours during the

Surgery to remove the thyroid is a cure to eliminate hyperthyroidism, but a thyroidectomy will require hormone medication for the rest of the animal’s life. As with any surgery with anesthesia, there is a risk, and since the parathyroid gland is in close proximity to the thyroid gland, care must be taken to not damage the parathyroid gland. Medication to control the production of excess T3 and T4 hormone is a treatment, not a cure for the disease. However, if the animal has side effects which have to be dealt with, daily dosing of anti-thyroid medication, and veterinarian visits for blood tests fall to the responsibility of the owner. Radioactive iodine therapy is a safe, effective way to kill the thyroid abnormal tissue, providing another cure for hyperthyroidism. An injection of the radioactive iodine is performed by the veterinarian and the iodine is engrossed by the bloodstream, with no adverse side effects or the risk of anesthesia. Since this treatment is radioactive, hospitalization after injection must be adhered until the

Radiation therapy is the use of high-energy radiation from x-rays, gamma rays, neutrons, protons, and other sources to kill cancer cells and shrink tumors (National Cancer Institute, 2016). One of the main purposes of radiation is to preserve the normal cells while killing the cancer cells. To fully understand the importance of radiation therapy it is imperative to understand its discovery. The discovery of radioactivity is attributed to Henri Becquerel in Paris. His discovery was purely accidental, as most discoveries are, while attempting an experiment that utilized the sun, uranium, and photographic plates. On 26-27 February 1896, Henri Becquerel took the uranium and photographic plates wrapped in black paper to initiate his experiment by placing them in the path of sun light, but to his misfortune it was overcast both days. Thinking that his experiment was a failure, Becquerel decided to develop the photographic plates and found that uranium did not need the sun’s rays to emit radiation due to its own radioactive properties, thus discovering radioactivity. The actual term “radioactivity” was coined by Marie Curie, a Polish born physicist, who along with her husband had been studying the phenomenon that was discovered by Becquerel (Lawrence Berkely National Lab, 2000).

Radioactive Iodine I-131(131I) therapy is a treatment for an overactive thyroid, a condition called hyperthyroidism. Hyperthyroidism can be caused by Graves' disease, in which the entire thyroid gland is overactive, or by nodules within the gland which are locally overactive in producing too much thyroid hormone.

The patients should be educated on carefully monitored to ensure adequate iodine intake while avoiding iodine excess. Per World Health Organization (WHO) data,

Iodine is create in a cyclotron by proton irradiation of xenon in a capsule. Iodine-123 gives a lower radiation dose to the patient and the gamma ray energy of 159 keV that suited with gamma camera than I-131. Then, tissue will be effectively penetrate without excessive radiation dose by gamma ray. It have been labelled by using I-123 and the number will be increase.

A gamma ray is a form of electromagnetic radiation that consists of high-energy protons due to its extremely high frequency wavelengths. Gamma rays ionizing radiation, meaning that they are hazardous because they carry enough energy to free electrons from atoms and molecules, this, in turn, gives them higher penetrating power than any other form of radiation. Another type of electromagnetic radiation is X-radiation, which shares the name of its components, X-rays, with the well-known medical imaging method. While these two are scientifically classified as separate forms of radiation, they are extremely similar to the point where there is only two known ways to determine if the radiation being emitted is one or the other, and both of these methods have cases where there are exceptions. The first method is to compare where the radiation is originating from, with regular gamma rays coming from the nucleus of an atom and X-rays being emitted by electrons. This method has two primary issues, being that 1- the precise point of origin cannot always be pinpointed and 2- that there are actually a number of much less common processes that can produce the same high-energy photons. The second method is to determine the variant of rays by the wavelength of the radiation, with any wavelength shorter than some

L-tyrosine is considered to be a natural treatment for thyroid health. Do not take it if you take prescription drugs to treat your thyroid condition and do not take it if you have high blood pressure. Otherwise, this amino acid works to enhance the functioning of your thyroid and you may find it beneficial.

There are many advantages and disadvantages to the use of radioactive elements in medicines. Some advantages include the fact that
