The Pros And Cons Of Radioactivity

Radiotherapy, also called radiation therapy, is the treatment of cancer and other diseases with radiation. Radiotherapy is used when the entire primary tumor cannot be surgically removed. Radiotherapy deposits energy

Furthermore, X-ray of higher energy than required for imaging is used for radiation therapy. The radiation therapy makes use of ionization radiation (and no images) for the treatment of diseases, such as

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

Radiation (also known as nuclear radiation) refers to particles or waves emitted by radioactive substance. Nuclear radiation comes from the waves from a nucleus. Ionising radiation can

Radioactivity is when energy is emitted from the nucleus due to the nucleus being unstable. The 3 types of radiation are Alpha ,Beta and gamma. Alpha particles have 2 protons and two neutrons. Examples of radioactive nuclei that emit alpha radiation. Are : uranium, thorium, actinium, and radium They are very ionising so they give energy off onto whatever they are in contact with. Therefore, it loses energy more quickly. They are not very penetrating so can be stopped by a piece of paper or skin. Beta particles have 1

Medicine has developed into an astonishing work of pure art over the years. From an old village healer crushing the simplest herbs in ancient times, to large machines administering chemical formulas to patients today. The newest addition to this artwork is Nuclear Medicine. Nuclear Medicine is a medicine that deals with the use of radioactive substances entering the body to attach/ attack cells. Whether it be to diagnose, test, or to treat, this nuclear technology has driven the medical and chemistry world into the future.

To understand what a radioactive isotope is a basic understanding of the atom is necessary. Atoms are comprised of three subatomic particles : protons, neutrons and electrons. Protons and neutrons bind together to form the nucleus of the atom, while the electrons surround and orbit the

Doctors had been using radiation to destroy cancerous cells since the unfolding of X-rays and radium in the 1890s, but both techniques had their own issues. X-ray machines were complicated to make use of, and radium implanted near tumors. In addition, X-rays weren’t strong enough to be entirely effective, and as for both of them, they were quite expensive.

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.

Who would have thought we would be using nuclear substances for medical purposes? Well, we are many different ways. I am going to discuss a test called the Indium Scan; this test requires the use of nuclear substances being injected into the blood stream via an IV. The amount of Indium that is giving is based on the patient and what the doctor feels as appropriate.

The radiological elements have been of great use to communities as a source of power generation, scientific experiments, treatments, and for the detection of various illnesses. although, these same materials have caused great harm to people and communities as well. The radiological material has been used during war time and have also been accidentally release causing harm, injury, and death to people. The United States government regulates these materials and dictates who can possess them and how they must store, safeguard, and dispose of them. The threat of terrorism is of great concern regarding radiological material as this could be used to intentionally

Radiology is a territory of therapeutic science that includes the finding and assessment of conditions in the body by means of the utilization of electronic imaging. This is an incredible path for us to have the capacity to see what is going ahead inside the body in extraordinary point of interest without needing to slice open the patient to see within his/her body, which can be conceivably extremely perilous and hazardous. It is far less complex and faster to utilize imaging and frequently more exact also in light of the fact that, you

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

Radium is used in luminous paint, clock dials, doorknobs and other objects to make them more visible in the dark. Radium is also used in the treatment of some cancers, and cancer therapy. But like all treatments and the prolong exposure to this radioactive element there are possible side effects including diarrhoea and sickness, low level of blood cells, increased risk of infection, and anaemia. Polonium is a extremely rare in its natural state and just like radium had few commercial uses because it is extremely radioactive. Polonium has been used as a static eliminator, heat source, and poison. The use of polonium has a poison became famous with the murder of Alexander Litvinenko. Polonium is harmless to the exterior body but once it is inhaled or consumed, the radiation causes damage to internal
