Express your answer as a nuclear equation.
Part A Write the balanced nuclear equation for the decay of Ra-226
Part B Write the balanced nuclear equation for the decay of Rn-222.
Part C If a room contains 23000 atoms of radon-222, how many atoms of radon-222 remain after 15.2 days?
Part D Suppose a room has a volume of 62000 L (6.2Ã104L). If the radon level is the maximum allowed (4 pCi/L), how many alpha particles are emitted from Rn-222 in 1 day? Assume that radon level is constant during this day.
(1 Ci = 3.7Ã1010 disintegrations/s)
Please help I have no idea how to do these
