| Even a seemingly tiny piece of radioisotope like plutonium can be emitting many millions of alpha, beta or gamma particles per week. |
| Gamma decay does not generally affect the mass and atomic number of the radioisotope. |
| In other words, each radioisotope has its own decay constant, abbreviated λ, which provides a measure of its intrinsic rapidity of decay. |
| Each radioisotope has a unique half-life and can be a fraction of a second or billions of years. |
| In essence, the process involves binding a radioisotope to a compound that has a specific affinity for an organ or region of the body. |
| The region of the lesion is injected with a blue dye and radioisotope tracer. |
