What are radioactive substances? How are they used and what are some examples?

Uses of radioactive substances

These instruments provide doctors with color images that show the shapes and details of internal organs. Still, it's good to know the sources of your exposure. One can propose that the presence of nuclear weapons has prevented war, but also that they have made the consequences of possible war much much worse than before. In nuclear power plants, uranium is used to produce electricity. It is a good idea to ventilate basements and have them checked, particularly in areas of the country where radon is common. Diagnostic Uses of Radioactive Materials Tracers: bone scans, kidney scans, and others. Radioactive Function in Daily Life The use of radioactive chemicals is generally divided into 2, i.

10 Radioactive Everyday Products

Uses of radioactive substances

Many are used commercially and medically, and others are just nuisances. There are a lot of different types of radiation: the light coming from a household lamp is a type of radiation, and the microwaves that cook your food are radiation. As of 2003 the isotopes , , , , , , , , , , , and were most commonly used by the oil and gas industry because they are easily identified and measured. Companies that produce and sell radioactive materials are licensed and inspected by the U. There are three main types of therapy in nuclear medicine.

11.4: Uses of Radioactive Isotopes

Uses of radioactive substances

This Americium produces alpha particles radiation , which then collides with oxygen and nitrogen in the air to produce ions. A more serious problem is if the radioactive source gets into the body, either into the lungs through inhalation of radioactive dust or ingestion by eating or drinking radioactive material. This exposure kills a lot of the bacteria that cause spoilage, so the produce stays fresh longer. Well Logging Devices These devices are generally found in areas where exploration for minerals is occurring, such as coal, oil, natural gas. One of the main tests is to determine if the pharmaceutical is going to other parts of the body than the intended target and what effect it has on the non-target areas.

Diagnostics: Medical Uses of Radioactive Materials

Uses of radioactive substances

By adding a radioactive tag to the pharmaceutical, researchers can pinpoint all parts of the body and the concentration that accumulates in non-target areas. The core reaction by an unstable element emits radiation and the involved elements are called radioactive elements. In fact, ultraviolet light a form of radiation is already used to disinfect drinking water in some homes. Sterilising By: Joanna, Rhiann, Ella, Michela Even after it has been packaged, gamma rays can be used to kill bacteria, mould and insects in food. Brazil nuts are probably the most radioactive food you can eat. In almost all cases, you get more exposure to radiation if you take a ride in a plane or get a dental x-ray.

Radioactivity

Uses of radioactive substances

Alpha particles are the nuclei of helium atoms. We choose a source with a long half-life so that it does not need to be replaced often. Measurements are conducted in a non-intrusive manner whereby the radiation emissions are measured without requiring the container to be opened or the item to be physically altered. Through x-rays, it can be evident if the distribution of metal is evenly disseminated with no cavity. Also read about the negative impacts of biotechnology in agriculture.

NRC: Backgrounder on Medical Use of Radioactive Materials

Uses of radioactive substances

For therapy, radioactive materials are used to kill cancerous tissue, shrink a tumor or reduce pain. Most radioactive materials used in nuclear medicine are isotopes, because a particular medical use will require a given isotope's specific radioactive properties. The actual size of the sources inside the devices is generally small. Based on long-term experience and cooperation with customers, Mirion constantly improves and extends its range of military products, providing new solutions and innovative technologies against new threats to protect global defense forces. However, therapeutic applications usually require much larger doses because their purpose is to preferentially kill diseased tissues.
