The radioactivity of iodine-131 (practice) Khan Academy

WebThe iodine-131 has a half-life of 8.02 days (692928 sec), and therefore its decay constant is: Using this value for the decay constant, we can determine the activity of the sample: 3) and 4) The number of iodine-131 atoms that will remain in 50 days (N 50d ) and the time it will take for the activity to reach 0.1 mCi can be calculated using the ...

http://www.actforlibraries.org/understanding-the-half-life-of-iodine-131/ Web131 I (half-life 8 days) is a strong γ-emitter, but due to its mode of β-decay, it is used for β-therapy, commonly in treating thyroid cancer. Dual-purpose theranostic radionuclides, for example, 131 I, or the pair 124 I/ 131 I can be used for imaging followed by therapy using the same radiolabeling procedure. WebDec 23, 2015 · 1/8 As you know, an isotope's nuclear half-life tells you how much time must pass in order for half of an initial sample of this isotope to undergo radioactive decay. In other words, an isotope's half-life tells you how much must pass in order for a sample to be reduced to half of its initial value. If you take A_0 to be the initial sample of an isotope, … honda cleveland tennessee
