How Does Nuclear Decay Place

Nuclear medicine is a certain branch of medicine that uses a specific type of radiation to give out important information about how a person's specific organs work. As well as, showing the organ and treating a disease that is inside of it. When information gets viewed by special physicians, they make sure to get a quick, accurate diagnosis of what the patient's illness is right away. The main organs that can be easily imaged by the nuclear medicine is the thyroid, bones, heart, liver, lungs, and the gallbladder. There are many hospitals that use the radiation; called radioisotope, in medicines. The most common one is named Technetium-99, which is used in medical diagnostic procedures annually. Nuclear medicine was created in the 1950s by physicians

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.

There are two other isotopes of technetium. One being technetium 98 and the other 99. Both of these have dramatically longer half-lives than there partner technetium 99m.

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.

Your health care provider will inject a small amount of radioactive tracer through the tube.

The following are some examples that are detected by this diagnostic tool: cancer, brain disorders, heart problems and problems in the central nervous system (Healthline, 2015). One of the brain disorders that PET can detect is Alzheimer’s disease. The patient would be advised not to eat or drink anything for 4-6 hours prior to the exam. The patient is injected with a dye called a radioisotope to demonstrate the function of a body part to rule out a diagnosis. Fluorodeoxyglucose (FDG) is the most common radioisotope used in PET. After the patient is injected, the radioisotope is absorbed by the tissues and organs (Dolson, L., 2001). When PET is used as a diagnostic tool for cancer, the clinician is then able to see how the malignant tumor is developing or if it has moved to other areas. It also allows the clinician to see how the malignancy is reacting to chemotherapy. PET scans show problems at the cellular level, therefore giving your clinician the best possible view of complex systemic diseases (Healthline, 2015). The tracers are normally out of the patient’s system within two days after a PET scan, but the patient should drink plenty of fluids afterward to help speed up the process of expelling the tracer.

A very common problem is when people are working in the field of radioactive milling, enrichment, reprocessing, waste storage, meltdown, etc. are known to suffer from the radiation from nuclear material. Sometimes patients are required to follow special preparation beforehand to achieve accurate results, for example certain medication may need to be stopped or a certain diet must be followed. A major drawback of radiation therapy is the collateral damage it causes to surrounding tissues in organs, although improvements, have made targeting more precise, it is impossible to administer ionising radiation to cancerous tissue without harming healthy

As an example: patient can be given a dye injection to detect arthritis or other conditions. Depending on the chemical substance used, the radiopharmaceutical concentrates in the part of the body being investigated, for example the skeleton, lungs, heart or liver, and gives off gamma rays. Bone scanning technique is being used to detect radiation from a radioactive substance (technetium-pp methyldiphosphate). When injected into the body, it collects in the bone tissue, as the bone tissue is good at accumulating phosphorus compounds. The substance accumulates in areas of high metabolic activity, and so the image produced shows "bright spots" of high activity and "dark spots" of low activity. Bone scanning with nuclear medicine can be an important step in diagnosing and assessing treatment of various kinds of cancer, including breast cancer. On an x-ray, one might see that the bone is not broken, but on a bone scan, physicians can see metabolic changes caused by fine fractures, small tumors, or degenerative diseases such as

Diagnosis- Radiation in medicine helps medical tests allow doctors to see inside the body, so doctors can diagnose, and treat conditions for humans and animals. Some tests expose ionizing radiation which put patients at risk, could cause death.

When a heavy nucleus absorbs neutron energy, it gets unstable and might split into two light nuclei by nuclear fission.

Radiation is a form of energy that can enter the cells in your body. Radiation is used in some common medical procedures. X-rays and gamma rays are some of the most common types of radiation used in imaging tests. These rays let health care providers create images of the organs and tissues inside the body to help them make a diagnosis.

The estimated rates of exposure, stated previously, is important for estimating short and long term effects on the exposed populations. Especially the exposed children, because they are at higher risk for future radiation exposure effects, as explained by the Law of Bergonie and Tribondeau. The exposed children need to be monitored because they will most likely require treatment, as they get older due to their sensitive thyroid

Fission is another way for saying splitting. Splitting a nucleus is called nuclear fission. Uranium or plutonium isotopes are commonly used in nuclear reactors, because their atoms have relatively large nuclei that are fairly easier to slip, especially when collided with neutrons. When a uranium-235 or plutonium-239 nucleus is hit by a neutron, the following happens:

Nuclear medicine imaging uses small amounts of radioactive materials called radiotracers that are typically injected into the bloodstream, inhaled or swallowed.

Radiation is used for many things. Before they knew it was dangerous, people used radiation for almost everything. They used it for its ability to glow in the dark, put it in paint to make the colors vibrant, and even went so far as to take a bath in it to cleanse their body. Today, many types of cancer treatments use a form of radiation to target and kill the cancer cells. It is also used in hospitals to sterilize needles and other things used in procedures.
