Radiation exposure and effective dose received through two routes of exposure, viz. external and internal, via inhalation, by residents of coastal villages belonging to Natural High Background Radiation Areas (NHBRA) of Kanyakumari District and Tamil Nadu inIndiawere studied. While the indoor gamma radiation levels were monitored using Thermo Luminescent Dosimeters (TLDs), the indoor radon and thoron gas concentrations were measured using twin chamber dosimeters employing Solid State Nuclear Track Detectors (SSNTDs, LR-115-II). The average total annual effective dose was estimated and found to be varied from 2.37 to8.64 mSv.

“…The SSNTD technique has also been used for determining alpha and beta dose-rates, the radon diffusion coefficient and radon exhalation rate in various quaternary samples [5,9]. This technique has been previously used to study the indoor radon level in different dwellings [10,11,12,13], and has been used to study the transfer of uranium and thorium from soil to different parts of medicinal plant [14]. …”

The paper presents results of radon ( 222 Rn) and thoron ( 220 Rn) levels in different parts of some selected plants used in Moroccan cooking and traditional medicine. Plant uptake of radionuclide is one of many vectors for introduction of contaminants into the human food chain. Thus, it is critical to understand the soil-plant relationships that control nuclide bioavailability. The radon and thoron concentrations have been determined in the studied samples and their corresponding soils, and that using the technique based on two types of solid state nuclear track detectors ( Rn from soil to parts of various studied plants have been determined. TF for roots were higher than those for stems and leaves. The radon and thoron activities in the soils have been found varying from 0.87 ± 0.06Bq.kg -1 to 6.20 ± 0.47Bq.kg -1 and from 30 ± 2.30mBq.kg -1 to 195±16mBq.kg -1, respectively. These values are lower in the leaves and stems than those determined in the roots of the studied plants. The aim of this study was to analyze the radon transfer from soil to different compartments of these plants and then to evaluate the radiotoxicity caused by radon in order to contribute to the health risk assessment.
