A sample of drinking water collected from a suburban Boston municipal water system in 2002 contained 0.49 pCi/L of radon. Assume that this level of radioactivity was due to the decay of 222Rn (t1/2 = 3.8 days).What was the level of radioactivity of this nuclide in the sample? (Bq/L)How many disintegrations per hour would occur in 2.5 L of the water? (disintegrations/L)

Question

A sample of drinking water collected from a suburban Boston municipal water system in 2002 contained 0.49 pCi/L of radon. Assume that this level of radioactivity was due to the decay of ²²²Rn (t_1/2 = 3.8 days).

What was the level of radioactivity of this nuclide in the sample? (Bq/L)

How many disintegrations per hour would occur in 2.5 L of the water? (disintegrations/L)
