What are some uses of some radioactive elements??


1-      Uranium

a-       Nuclear weapons

b-      Nuclear power plants

c-       Used as yellow coloring (mostly to glass)

 

2-      Co-60

a-       Industrial purposes (used to detect flaws)

b-      Used as cancer therapy and x-rays

c-       Used to sterilize objects

 

3-      C-14

a-       Radiocarbon dating

b-      Elucidation of carbon pathway (photosynthesis)

c-       Helps in detecting abnormalities of metabolism

 

4-      Iodine

a-       Thyroid cancer treatment

b-      Diagnostic imaging

c-       Treatment of hyperthyroidism


 


Which use of radioactive elements should be ranked as number “1” when it comes to humanity (in my opinion)??


 


          In my opinion, the use of radioactive elements that I fined should be ranked as number “1” when it comes to humanity is the use of iodine to treat hyperthyroidism. I deeply believe in this because hyperthyroidism basically has no cure other than this cure. Hyperthyroidism is a disease in which the thyroid overproduces hormones. Some medicines decrease some of the symptoms of the disease, but the only way to cure hypothyroidism is by radioactive iodine.  Hyperdorism is treated by getting the patient to ingest a specific amount of iodine-131 and it stays in the body for about 3 days and for a week after the treatment the patient is not allowed to come in contact with people so much due to the radioactivity of the iodine. The iodine is extracted by the body through first week after the procedure. The reason why iodine treats hyperthyroidism is because it decreases the production of thyroxine which causes the disease.

Uranium is used in military to power nuclear weapons. 


Iodine can prevent thyroid damage. 

Cobalt-60

Cobalt -60 is a radioactive isotope of the element Cobalt-59 with the atomic mass of 27. Cobalt-60 is naturally unstable, hence it could emit gamma rays that powerfully penetrate objects . The isotope has a long life perseverance that is up to 5.3 years. 

 Cobalt-60 has various applications in diverse fields, and yet the most appealing one is the medical approach. Due to its precise ray emission, cobalt-60 could be used to treat tumors all over the body, especially the brain ones. It has  the capacity to treat cancer; in fact, doctors have been using it for over 60 years. The gamma radiation, when exposed to a body part, damages the DNA of a cell, interrupting the growth of cancerous cells. 

Not only the cobalt-60 has been used in the medical approach, but it has also been used in the sterilization of insects, the sterilization of food, and the detection of explosive devices. Unlike the other elements- iodine, carbon-14, and uranium-  Cobalt is used to enrich the human life and the environment rather than risking it. Moreover, in my opionion, i think that Cobalt-60 shall be ranked as 1 in regards to humanity.

       Most Important is Medicine because this application targets a problem that lots of people suffer from which is Cancer, Cobalt-60 is extensively used as a radiation source to kill or terminate the development of Cancer. 




      Another Example is Carbon-14 and it's use in the detection of detecting the age of artifacts that once lived.




      A significant amount of Carbon-14 is naturally found in the upper atmosphere. Living things use some of the Carbon -14 in their tissues, which builds up at a low but constant level. Once that living thing dies. It gradually loses Carbon -14 and the Carbon-14 that was once in the tissue decays. Until there is no longer Carbon-14 in a living things tissue. Then when researchers analyze and examine a specimen of the once-living artifact they measure the amount of Carbon-14 and then compare it to a known constant level.
 



  An average or approximate age of the artifact can be determined by the researchers. Scientists were able to use this method to show that the age of a mummified body found in the ice of the Alps was around approximately 5,300 years ago !

are  Co-60 , Uranium, iodine, C-14
So those are 4 main applications were each one have more than one use .
 I believe the most useful one for humanity (in my opinion) is Co-60 because mainly it is talking about medical approaches and medicinal and medicine is something so important to humans because there some people who could have cancer and it could be only solved with radioactive isotopes and human lifes is the most important thing so nothing from the applications above will help people like the C-60
For example gamma rays can destroy cancer cells also as you see in the link bellow there are more than one thing that helps people https://www.google.com.eg/search?q=applications+for+co-60+radioactive+isotope+benefit&source=lnms&tbm=isch&sa=X&ved=0ahUKEwj43s3q_9bdAhWPZFAKHRkRDCwQ_AUIDigB&biw=1360&bih=548#imgrc=vmvsBF5kVkRbTM:

70% of cancer sufferers who require radiotherapy, receive radiation from cobalt-60.
as you see above this is big number 
also Co-60 have another benifits for example
Cobalt-57 and Cobalt-58
This is a test used to determine whether a patient is absorbing Vitamin B12 normally. The Schilling test is primarily used to test for a specific type of anaemia

so i can conclude and say that Co-60 is the most beneficial one because it is the only kind that can save human life and human life's is the most important.

 Radioactive isotopes

  1. Uses of Uranium

  • Uranium provides nuclear fuel used to generate electricity in nuclear power stations. 

  • fissionable fuel (a fuel that can sustain a chain reaction). 


  • Uranium is also used by the military to power nuclear submarines and in nuclear weapons.

  • Depleted uranium can be used as ballast in ships and counterweights for aircraft. .


  1. Uses of cobalt-60

  • accurately detecting of explosive devices

  • preserving food

  • It is used radiotherapy

  • Gamma  radiation emitted from cobalt 60 is used

  • Sterilization of Medical Supplies, ornaments, or even tissues

  • Cobalt-60 can eliminate microorganisms such as bacteria.
 
  • It can damage the DNA of living cells as a result of its ionization and therefore prevent them from  reproducing. 


  1. uses of iodine

  • Iodine promotes thyroid health  and can be used in sterilization

  1. Uses of Carbon-14

  • Carbon 14 is used to date objects containing organic material

  • Used in studying abnormalities of metabolism like diabetes, gout, and anemia.


  1. The element that should be ranked number 1 Regarding humanity

In my opinion I believe cobalt-60 should be ranked number 1, cobalt-60 is used in Sterilization which is a very important factor of medical health, if  absent it would cause  serious issues, infection is one example. 
Cobalt 60 also have the ability to damage a living cell’s DNA and stop it from reproducing, which means it can enable us of eliminating unwanted or harmful bacterial communities or maybe to tumor reproducing cells?

Iodine is important in medicine, in both radioactive and non-radioactive forms. Iodide and thyroxin, which contains iodine, are used inside the body.

A solution containing potassium iodide (KI) and iodine in alcohol is used to disinfect external wounds. Elemental iodine is also used as a disinfectant.

Silver iodide is used in photography.
Iodine is sometimes added to table salt to prevent thyroid disease.

Iodine’s other uses include catalysts, animal feeds and printing inks and dyes.

Uranium:

Uranium is a very important element because it provides us with nuclear fuel used to generate electricity in nuclear power stations. It is also the major material from which other synthetic transuranium elements are made.

Uranium fuel, used in nuclear reactors, is enriched with uranium-235. The chain reaction is carefully controlled using neutron-absorbing materials. The heat generated by the fuel is used to create steam to turn turbines and generate electrical power.

Uranium is also used by the military to power nuclear submarines and in nuclear weapons.

Depleted uranium is uranium that has much less uranium-235 than natural uranium. It is considerably less radioactive than natural uranium. It is a dense metal that can be used as ballast for ships and counterweights for aircraft. It is also used in ammunition and armour.

Co-60:

Cobalt-60 is widely used as a medical and industrial source of radiation. Medical use consists primarily of cancer radiotherapy. Industrial uses include testing welds and castings and a large variety of measurement and test instruments, such as leveling devices and thickness gauges. It is also used to sterilize instruments and to irradiate food to kill microbes and prevent spoilage.

C-14:

It is used in Radiocarbon dating of an object. The main purpose of this technique is to make an estimate of the age of that object and the best part is, the estimate is almost perfect/accurate.

Most of the objects, if not all, that we see around us are made of carbon compounds. For example, plastic, stones, plants, animals and so on. These Carbon atoms are C-12 i.e the gram atomic mass of Carbon atom is 12. Now with time, these Carbon atoms, due to very little radioactivity, change into C-14, the speed of the reaction being very very slow.

By calculating the proportion of C-12 and C-14 in an object, one can easily estimate the time when the reaction had started or in simple words, the age of the object, using simple Chemical kinetics.

Which is more useful:

I, personally, think Iodine is the most useful one.
