WebRecall that: 10 0 = 1 (anything raised to the 0 power equals 1) 10 1 = 10 (anything raised to the 1st power is the value itself) 10 2 = 10 × 10 = 100 10 3 = 10 × 10 × 10 = 1,000. So the fraction of (numerator/denominator) can be multiplied by 1, 10, 100, 1000, and so on. This multiplier varies by measure and will be addressed in each section.

"WebThe counting rate is equal to some fixed fraction of the rate of decay. Counting rate = (factor) x (rate of decay) The rate of decay ( D N/ D t) is found to be proportional to the number of unstable nuclei (N): decay rate = D N/ D t = - kN . This is mathematically described as N = N°e -kt or ln (N) = ln (N°)- kt " - Equation for count rate
