WebWe measure the decay constant, which can be done in a lab fairly easily. This is the constant we would normally use in computations, not the half-life. However, the half-life can be calculated from the decay constant as follows: half-life = ln (2) / (decay constant). To measure the decay constant, we take a sample of known mass and measure the ...
