Modeling of radon and its short-lived decay products emanating from tap water used inside a house: Dose to adult members of the public

Radon concentrations are measured in the tap water collected in different areas in Marrakech (Morocco) by using liquid scintillation techniques. The concentrations due to radon and its short-lived decay products emanating from the tap water used inside different compartments of the house were determined. Alpha activities due to the 218Po and 214Po short-lived radon decay products were evaluated in various compartments of the respiratory tract of adult members of the public. The committed equivalent doses due to the 218Po and 214Po short-lived progeny of radon were evaluated in different tissues of the respiratory tract by the frequencies of using the various parts of the house.
