PPT-AUTORADIOGRAPHY Radioisotopes

Isotopeswhich have same chemical but different physical properties having radioactivity Natural occurrence is rare because of its instability They emit different radiations such as α β. Usually we use this technique to measure the function of the left ventricle LV which is the major pumping chamber of the heart The LV receives blood from the lungs and pumps blood to the rest of the body A gated nuclear angiogram is more accurate th Knowledge of subatomic particles has led to many advancements- unfortunately besides the advancements in power plants there has been costs-nuclear warfare and waste.
