Radio isotopic labelling in studying or examining the human body Adam El-Batal AshrafTayfour Hussein Hamid Jim Lin
Radio isotopes vs. Isotopes • Isotopes: are atoms with the same number of protons but have a different number of neutrons • Radio isotopes: Is an isotope that emits radioactive gamma rays or subatomic particles • They have unstable nuclei therefore making them unstable and radioactive ex) some uranium isotopes
Enzymes • They are protein catalysts • They accelerate chemical reactions by lowering the activation energy
Enzymes and Medicine • They can be used to diagnose diseases Ex) liver diseases can cause enzymes to flow into bloodstream therefore medical imaging can tell us if there is a liver defect by examining the blood
Why enzymes are used in medical imaging • They can help prevent side effects from occurring on a patient • They reduce the costs of medicine because they can be used in small quantities (they reduce the energy needed for chemical reactions)
Radio isotopes and medicine • Radioisotopes and radiation have been used in the medical field to treat diseases such as cancer, as well as find abnormalities with the human body ,then using radiation to weaken or destroy particular targeted cells.
Radio isotopic scan • Radiologists can use radioactive doses to search for abnormalities in the human body • Radioactive doses are injected through a vein in the arm • Radio isotopes will then start to decay and release energy and radiation • Then, through an X-ray, doctors can see if a patient has any diseases or abnormalities such as cancer
Risks of this technology • Radiation can have negative side effects on cells in the body • However the concentration of the radio isotopes is usually too low to do any damage (modern technology uses the smallest doses possible)
Reasons why this technology is useful • It is a quick and effective way to detect abnormalities in the body. • The radiation dose is very low therefore there is little risk of damage from the radiation • Energy inside the radioisotopes doesn’t get used up right away, therefore making it more effective
Radio isotopes and agriculture • In food preservation, radiation can prevent root block plants germinate after harvest • It can used to kill some parasites and insects on plants • Also, it can be used to control some of the stored fruit and vegetables maturity.
