Radon and thoron exhalation rate in the soil of Western Haryana, India

Environmental Monitoring and Assessment, 2022
Abstract This study, reports the exhalation rates of radon and thoron from surface soil collected from 60 rural sites of district Hisar, Haryana, India. The exhalation rates of Rn222 (Radon)& Rn220(Thoron) were measured by portable SMART RnDuo (AQTEK SYSTEMS) using a mass accumulation chamber which is equipped with a scintillation material ...

Environmental radon, its exhalation rates and activity concentration of 226Ra, 232Th, and 40kK in Northern India [PDF]

Nuclear Technology and Radiation Protection, 2020
Human beings are constantly exposed to radioactivity in the environment. As they are major sources of harmful radiation, radionuclides found in the atmosphere might result in a substantial potential risk to living beings. On the Earth's surface,

Foraminifera assemblages from Fantangisña serpentinite mud seamount in the NW Pacific Ocean during the Pleistocene (IODP Expedition 366)

Journal of Quaternary Science, Volume 38, Issue 7, Page 1103-1127, October 2023., 2023
ABSTRACT The Mariana forearc system, in the northwestern Pacific, is known as the only convergent margin setting with currently active serpentine mud volcanism. The Fantangisña serpentinite mud volcano lies 62 km west of the Mariana trench, within the influence of the North Equatorial Current (NEC).

Assessment of Seasonal Radon Concentration in Dwellings and Soils in Selected Areas in Ga East, Greater Accra Region of Ghana

Journal of Environmental and Public Health, Volume 2022, Issue 1, 2022., 2022
Seasonal radon levels have been studied in dwellings and soils in selected areas in Ga East, Greater Accra Region of Ghana using LR‐115‐type II (SSNTDs). This study was conducted to determine the seasonal correlation between soil and dwelling radon concentrations.

Estimation of natural radionuclide and exhalation rates of environmental radioactive pollutants from the soil of northern India

Nuclear Engineering and Technology, 2020
The estimation of radioactivity level is vital for population health risk assessment and geological point of view and can be evaluated as rate of exhalation and source concentration (226Ra, 232Th and 40K).

Investigating Fracture Network Deformation Using Noble Gas Release

Geofluids, Volume 2021, Issue 1, 2021., 2021
We investigate deformation mechanics of fracture networks in unsaturated fractured rocks from subsurface conventional detonation using dynamic noble gas measurements and changes in air permeability. We dynamically measured the noble gas isotopic composition and helium exhalation of downhole gas before and after a large subsurface conventional ...

Radon-thoron measurements in air and soil from some districts of northern part of India [PDF]

Nuclear Technology and Radiation Protection, 2015
Radon, thoron and their progenies in the indoor environment are considered as one of the health hazards. The alpha emitting nature of these gases made it possible to detect in indoor environment with the help of nuclear track detector techniques.

Tukey Control Chart for Radon Monitoring in Relation to the Seismic Activity

Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021
Radon is one of the precursory phenomena that exist in connection to the occurrence of earthquakes and may have potential in forecasting these hazards. The data set in this study contains the observations of radon from August 01, 2014, to January 31, 2015, collected in Sobra city, northern Pakistan.

INFLUENCE OF SAMPLING FLOW RATE ON THORON EXHALATION RATE MEASUREMENTS BY THE CIRCULATION METHOD

Radiation Protection Dosimetry, 2022
AbstractResearchers have used various methods to obtain the exhalation rates of radon and thoron from soil and building materials. One of the typical methods for radon exhalation rate is the circulation method using an accumulation container, an external or internal sampling pump and a continuous radon monitor.

Indoor radon and thoron from building materials: Analysis of humidity, air exchange rate, and dose assessment

Nuclear Engineering and Technology, 2020
Building materials contribute significantly to the indoor radon and thoron levels. Therefore, parameters that influence the exhalation rates of radon and thoron from building material need to be analyzed closely.
