Question- A sample of drinking water collected from a suburban Boston municipal water system in 2002 contained 0.52 pCi/L of radon. Assume that this level of radioactivity was due to the decay of 222 Rn (half-life = 3.8 days)
What was the level of radioactivity of this nuclide in the sample?
How many disintegrations per hour would occur in 2.5 L of the water?
Write the complete solution in short and simple way
