WebHalf life of a radioactive substance is calculated by measuring the time it takes for its activity to decrease by half. A practical way to estimate half life is to measure the activity … WebIn this problem, we are given that it takes 444 years for the substance to lose 1/2 of its radioactive nuclei, so in each year, it will tick through only one-444th of its half-life. So our exponent is t/444. We then can say that N (t) = N₀ (1/2) ^ (t/444) You asked what the constant value is for mercury 194.
