WebSpecific isotopes find their way in the body to specific organs, and by emitting radiation from these locations, make the organ visible to a radiation-detecting camera. For example, thallium-201 concentrates in normal heart muscle, allowing determination by the dark areas on the film of the amount of damage caused by a heart attack ... WebBismuth (83 Bi) has 41 known isotopes, ranging from 184 Bi to 224 Bi. Bismuth has no stable isotopes, but does have one very long-lived isotope; thus, the standard atomic weight can be given as 208.980 40 (1).Although bismuth-209 is now known to be radioactive, it has classically been considered to be a stable isotope because it has a … WebStudy with Quizlet and memorize flashcards containing terms like The list below shows some events which took place at different periods in the geologic time scale.
