Is the cell phone a boon or curse? It means that you are always available and can be contacted by your loved ones, and you can contact them. On the other hand they can also call you at all hours and ask for a lift home rather than get themselves organised before they go.
Before we go into discussing radioactive isotopes, let's recall what an isotope is. Let's look at the picture of an atom below - it has a nucleus made up of protons and neutrons, with electrons around the nucleus.
All the atoms of an element have the same number of protons, but the number of their neutrons can differ. If this happens, then we can call these isotopes of an element.
Isotopes have the same number of protons, but they differ in the number of neutrons. Made of Protons and Neutrons For instance, below, we have the isotopes of hydrogen.
Here, you can see that the number of protons and electrons are the same, but for the three isotopes of hydrogen, the number of neutrons differ.
Isotopes of Hydrogen Now that we recalled what isotopes are, what makes them radioactive? When I think about the word 'radioactive', I think about a unique and unstable type of energy.
If an isotope has an unstable nucleus that breaks down to emit radiation, then these are what we call radioactive isotopes, also known as radioisotopes. Radioactive isotopes have an unstable nucleus that decays or emits excess energy or radiation until the nucleus Radioactive isotopes as a boon stable.
They can be naturally occurring or artificial isotopes of an element. Uses of Radioactive Isotopes There are about 50 naturally occurring radioactive isotopes, and the rest are artificial.
We probably don't know all of the many uses these radioactive isotopes have, or the benefits they bring in various fields.
What are the uses of these radioactive isotopes? Medicine There are many radioactive isotopes that are very beneficial in applications in medicine.
For instance, radioactive isotopes are used for radiation therapy, and for locating brain tumors. If for instance, you need to keep track of activities of your organs, radioactive isotopes are also used here.
Below is a table of some radioactive isotopes and their applications in medicine. It is very unpleasant, so to minimize food borne illnesses and food poisoning experiences, food needs to be treated.
To do this, it has to undergo irradiation, which commonly uses radioactive isotopes of cobalt Symbol Indicating Food was Treated with Radiation Besides preventing illness, irradiating food can help it stay fresher longer because it gets rid of microorganisms and bacteria that cause early spoilage.
The good news is, the irradiated food doesn't come in direct contact with the radioactive isotope, so the food won't be radioactive. Industrial Applications Do you ever notice when you buy paper that the thickness is uniform?
Have you also ever wondered how people know where oil wells should be drilled? Different industries like steel, paper and oil industries, among others, make use of radioactive isotopes as well. Below are some radioactive isotopes and how they are used industrially. Industrial Uses of Some Radioactive Isotopes Science and industry use radioisotopes in a variety of ways to improve productivity and, in some cases, to gain information that cannot be obtained in any other way.
Sealed radioactive sources are used in industrial radiography, gauging applications and mineral analysis. Short-lived radioactive material is used in flow tracing and mixing measurements. Various radioactive decay series are used to measure the ages of materials incorporating them.
Gamma sterilisation is used for medical supplies, some bulk commodities and, increasingly, for food preservation.
Nuclear techniques are increasingly used in science, industry and environmental management. The continuous analysis and rapid response of nuclear techniques, many involving radioisotopes, mean that reliable flow and analytic data can be constantly available. This results in reduced costs with increased product quality.
Neutron Techniques for Analysis Neutrons from a research reactor can interact with atoms in a sample causing the emission of gamma rays which, when analysed for characteristic energies and intensity, will identify the types and quantities of elements present.
TNC occurs immediately after a low-energy neutron is absorbed by a nucleus, NIS takes place instantly when a fast neutron collides with a nucleus. Most commercial analysers use californium neutron sources together with sodium iodide detectors and are mainly sensitive to TNC reactions.
Such equipment is used for a variety on on-line and on-belt analysis in the cement, mineral and coal industries.
A particular application of NIS is where a probe containing a neutron source can be lowered into a bore hole where the radiation is scattered by collisions with surrounding soil. Since hydrogen the major component of water is by far the best scattering atom, the number of neutrons returning to a detector in the probe is a function of the density of the water in the soil.Radioactive isotopes or radioisotopes are naturally or artificially created isotopes of chemical elements that have unstable nucleus.
These products emit rays like alpha, beta and gamma rays. After the nucleus splits, it decays and forms a different atom having different number of protons.

Radioactive isotopes are atoms with unstable atomic nuclei, and they emit energy and particles from the nucleus to tranmute (change) themselves into stable isotopes. Atomic energy a boon or a curse?
I think it's like many other things man has invented: fire, the wheel, aircraft, for example, they can all be used for good and bad, which means.

If an analogue of NE were tagged with a radioactive isotope, the analogue would be taken up by the tumor. This allows the tumor to “light up” with the released radiation from the radioisotope. Iobenguane was the analogue chosen, as it is a rather inert compound similar in structure to the neurotransmitter NE.
