چکیده
Ground atmosphere is characterized by low activity of radioactive gases and aerosols, which leads to some difficulties in the choice of control methods. Modeling techniques in these cases have undeniable advantages for determining the volumetric activity (VA) of radioactive gases and aerosols in the ground atmosphere. It is known that the activity of radon isotopes and aerosols decay products in the atmosphere in the same area is have variations depending on weather conditions, time of day and season of the year, the height above the ground. In the seasonal variation of radon activity in the air maximum shown in summer-autumn and a minimum in winter-spring. Throughout the day minimum is observed in the afternoon time (12-15 hours), and the maximum-after midnight (0-6 hours).

Mitigation of radon and thoron decay products by filtration.
Inhalation of indoor radon ((222)Rn) and thoron ((220)Rn) decay products is the most important source of exposure to ionizing radiation for the human respiratory tract. Decreasing ventilation rates due to energy saving reasons in new buildings suggest additional active mitigation techniques to reduce the exposure in homes with high radon and thoron concentrations but poor ventilation. Filtratio...
متن کاملA study on radon and thoron progeny levels in dwellings in South India
Background: Decay products of radon and thoron present in indoor environment are the most important sources of radiation from natural sources which affect human beings, since general public spend at lest 80% of their time in indoor. Materials and Methods: Air samples were collected for measuring the concentration of radon and thoron daughter products from various indoor environments d...
متن کاملA new thoron atmosphere reference measurement system.
A new thoron reference ((220)Rn) in air measurement system is developed at the LNE-LNHB with the collaboration of the IRSN. This measurement system is based on a reference volume with an alpha detector which is able to directly measure thoron and its decay products at atmospheric pressure. In order to improve the spectrum quality of the thoron progenies, we have applied an electric field to cat...

Liquid Scintillation Counting (LSC) is a measuring technique, broadly applied in environmental monitoring of different radionuclides. One of the possible applications of LSC is the measurement of radon and thoron progeny. There are certain advantages of this method, especially high counting efficiency for alpha and beta particles emitted by radon and thoron progeny. This advantage has been poin...

Indoor radon and thoron have been measured in the houses ofMoradabad District, Uttar Pradesh India, by means of solid state nuclear trackdetectors. Radon, an invisible radioactive gas, occurs naturally in indooratmospheres and along with thoron is the most important contribution of humanexposure to natural sources. Radon exists in soil gas building materials and indooratmosphere to name but a f...
