Investigate the decay of a radioactive substance. The half-life and the number of radioactive atoms can be adjusted, and theoretical or random decay can be observed. Data can be interpreted visually using a dynamic graph, a bar chart, and a table. Determine the half-lives of two sample isotopes as well as samples with randomly generated half-lives. The radioactive decay of certain number of atoms (mass) is exponential in time. Radioactive decay law: N = N.e-λt. The rate of nuclear decay is also measured in terms of half-lives. The half-life is the amount of time it takes for a given isotope to lose half of its radioactivity. decay can be observed. Data can be interpreted visually using a dynamic graph, a bar chart, and a table. Determine the half-lives of two sample isotopes as well as samples with randomly generated half-lives.

Radioactive Decay is a Random Process You can NEVER tell when an individual atom is going to decay. You can figure out approximately how many atoms in a group are going to decay in a certain time, but you cant tell which ones are going to blow. The timescale for radioactive decay is described by the quantity called a half-life. The smaller the chance of decay, the longer the half-life (time for half of the sample to decay) of the particular radioactive isotope. The cubes, for instance, have a longer half-life than the pennies. For uranium 238, the chance of decay is small: Its half-life is 4.5 billion years. Mar 01, 2001 · Incidentally, our formula for t gives us an easy way of finding the half-life, the time it takes for half the nuclei in a sample to decay. The half-life (often denoted t1/2) is just t (1/2) = (1/ l ) ln (2). The equivalent thickness for the medium in radiation attenuation is known as "half-value thickness".
