Study of radon (222Rn), thoron (220Rn) and their daughter products is an important aspect as they are the main contributors to the total radiation dose inhaled by human beings from natural radioactive sources. The contribution of radiation dose from daughter elements of 222Rn and 220Rn are more harmful and they cannot be neglected. The alpha-emitting, short-lived decay products are present everywhere in the environment in attached or unattached fractions of air particles. During inhalation, these daughter products stay in the lungs, which may lead to lung cancer.
