According to the u. s. environmental protection administration, the concentration of radon-222 in air in equilibrium with its short-lived daughters in a home at which remediation should be done is 4 pci/liter. this corresponds to how many atoms of radon-222 per cm? ? note: rn-222 half-life is given as 3.8 days.]
