Radioactivity has many different uses, it helps on areas such as science, geology, archeology and many more.
Radioactivity has different effect and even when it can have a lot of positive implications it can also have a lot of negative. The thing about radioactivity is that it can save millions of people from dying if used correctly but if used incorrectly it can kill and destroy entire cities. Radioactivity could be defined as the emission of radiation in the form of particles or high energy photons, creating a nuclear reaction. Radiation can be both natural and man made depending on the type, natural radiation comes from cosmic rays from outer space and the artificial radiation is mostly used in medical practises, nuclear weapon testing, smoke detectors etc. Isotopes are Isotopes are atoms with the same number of protons but that have a different number of neutrons or could also be described as elements with the same atomic number but different mass numbersRadioactive decay is the process in which when the nuclei of some isotopes are unstable they split up and release a radiation. When a radioactive isotope decays, it forms a different atom with a different number of protons, this is the only time you can see a changing element.
There are three types of Radioactive decay; Alpha, Beta and Gamma. During Alpha Decay an atom splits out two protons and two neutrons from its nucleus, alpha particles are unable to go through the outer layer of dead skin cells unless an alpha emitting substance is ingested in food or air. During beta decay due to the smaller mass, it is able to travel further and can be stopped by a thick piece of plastic, or even a stack of paper, it can go through skin a few centimeters. Finally Gamma radiation is the emission of an high-energy wave from the nucleus of an atom, Gamma waves can be stopped by a thick or dense enough material such as Uranium. Gamma rays have the ability of going through the human body and are commonly used on treatments such as chemotherapy for cancer.Radioactive Isotopes can be used for many different areas but on this case it is used for medicine, The radioactive isotopes were first used in medicine for diagnostic procedures during the early 1930s which created what we know today as nuclear medicine. Iodine 131 therapy uses radiation in order to damage the thyroid tissue, when treating thyroid cancer. This radiation is used to get rid of any excess of throat tissue and it can also be used to destroy cancer.
This Therapy is considered for patients with large tumours, used after a thyroidectomy to destroy any remaining cancerous thyroid tissue in the thyroid gland area, or to destroy any tumours that may have spread elsewhere in the body. radioactivity is also commonly used to sterilize surgery and other important medical equipment.Radioactive isotopes also have a big impact on nuclear weapons as well, they rae commonly used for therapy.The first example is the uranium fast breeder reactors. It is important to Remember that radiation treatment is for a serious disease, one that can kill you.
It is not for something that can be treated by other means.As everything radiation has pros and cons, a positive thing about radiation is that Radiation therapy relieves symptoms and pain caused by advanced cancers, it ha been proven to work for almost all types of cancer treatment. The cons are that not only the tumor is irradiated but also neighboring tissues which are not necessarily cancerous.
another positive aspect is that with skilled technicians and next-gen technology, Radiation Therapy is extremely effective at destroying cancer cells without damaging surrounding tissues. It is evident that radioactive isotopes have the power to cure or to destroy depending on how they are used therefore it is important to think all about the tests and consequences that may happen and keep them in mind before making a conclusion.
