Modeling radioactive decay in pennies
MODELING RADIOACTIVE DECAY WITH PENNIES ADVANCED STUDY ASSIGNMENT MODEL 2: RADIONUCLIDE HALF-LIFE The time required for half of a sample of a radionuclides (radioactive isotopes) to decay is called the half-life (units of time). Table 2 below illustrates the half-lives of several radioisotopes and the Table 2: Half-lives of some Radioisoto barium-131 carbon-14 chromium-51 cobalt-60 iodine-131 uranium-238 Radiation Half-life 11.6 days 5730 yrs 27.8 days 5.3 yrs 8.1 days 4.47. 109 yr Application detection of...
