The most abundant radon isotope is radon-222, which is an alpha emitter with a half-life of 3.8 days. The air in a house basement in Canada is found to have a radon level of 500 Bq m³. The World Health Organization's safe limit for radon is 100 Bq m³. How long will it take for the radon level to decay to 100 Bq m³ in a sample of air from this basement?
