“…The prepared samples were weighed into powder form and packaged in radon impervious plastic containers (2.5 inch in height and 3 inch in diameter) and encoded. The samples were stored for 40 days to provide balance between 226 Ra, 232 Th and their shortlived degradations 11,12 . Radioactivity measurements were performed by using NaI(Tl) detector based on gamma spectrometry system.…”

In Natural radioactive materials may be existing in the environmental substances that have uses in pharmacy and medicine as health supplements. In this study, natural radionuclides such as 226 Ra, 232 Th, and 40 K were measured in seven medicinal or herbal plants collected from the local market in Kars, Turkey were analysed. All samples were analysed by means of gamma-ray spectrometer using NaI(Tl) detector. The radioactivity concentrations were found to vary in the range of 16.39±2.2 to 32.76 ±3.5 Bqkg-1 for 226 Ra, 19.74±3.7 to 85.01±5.6 Bqkg-1 for 232 Th, and from 795.82±9.8 to 1056.28±14.4 Bqkg-1 for 40 K. Rosehip showed the lowest activity concentrations of 226 Ra, 232 Th and 40 K, while rumex patientia showed the highest activity concentration of 40 K. In this research study, we aimed to determine the activity concentrations of radionuclides in medicinal plants and provide useful information to carry out a dose assessment to be exposed to people using medicinal plants for healing various diseases.

“…The activity concentrations of 226 Ra, 232 Th, and 40 K for TT1 (perlite) and TT5 (zeolite) in this paper are higher than in previous studies. 27,29 The activity concentration of 226 Ra and 232 Th and 40 K for TT3 (pumice) is higher than that obtained by Kayakökü et al 29 and the activity concentration of pumice for 40K is smaller than that obtained by El-Mageed et al 46 The 226 Ra activity concentration of TT8 (sepiolite) is higher than that calculated by Hancerliogulları et al 28 The activity concentrations of 226 Ra, 232 Th, and 40 K are among the calculated by Turhan et al 47 and they are lower than calculated by Righi and Bruzzi. 48 The D, Ra eq , AGDE, ER, AEDE total , ELCR total , GRL, H in , and H ex of studied inorganic materials were obtained as given in Table 7.…”

“…In studies on their applications in these areas, there are various examples of radiological properties for inorganic minerals such as perlite, pumice, zeolite, sepiolite, and volcanic tuff. [27][28][29] Perlite is a light-structured volcanic rock that is a white powder of expanded aluminum that does not deteriorate and is characterized by increased porosity. 30 Vermiculite is a non-renewable substrate that greenhouse growers use to improve potting mix cation exchange capacity.…”

This study aims to examine the physicochemical and radiological properties of some inorganic materials which are perlite, vermiculite, pumice, rock wool, zeolite, expanded clay aggregate, volcanic tuff, and sepiolite used in soilless agriculture. Water saturation, pH, electrical conductivity, calcium carbonate equivalent, available potassium, available phosphorus, and organic matter analyses were implemented for inorganic materials. The elemental contents of the components for studied inorganic materials were obtained using inductively coupled plasma‐optical emission spectrometry (ICP‐OES). Furthermore, natural and artificial radionuclides of studied inorganic materials were calculated using gamma‐ray spectrometry. The pumice has the highest 226Ra activity concentration, and the zeolite has the highest 232Th and 40K activity concentrations. The 137Cs activity concentration is the maximum for perlite and it is the minimum for expanded clay aggregate. The zeolite has the highest radiological hazard parameters whereas those are the smallest for the rock wool. The Fe, Na, B, Ca, K, Si, P, S, and Mn are the primary components of the inorganic materials used in soilless agriculture. Consequently, this study is contributed to environmental and health problems of livings. In the future, transferred radionuclides from plant to livings assessment can be carried out for these inorganic materials used in soilless agriculture.

“…The Commission of International on Radiological Protection [ICRP, 1994] have been shown the dose equivalent limit of annual effective 1 mSvy −1 for the individual members of the public and 20 mSvy −1 for the radiation workers. The present range (14,512–18,497) of the excess lifetime cancer risk (ELCR) was higher than the limit of 1.45 of the worldwide average [ 50 , 64 ]. All the radiological hazard results indicated the presence of very high rates resulting in high human health risks.…”

This study aimed to evaluate the radiological hazards of uranium (238U), thorium (232Th), and potassium (40K) in microgranitic rocks from the southeastern part of Wadi Baroud, a northeastern desert of Egypt. The activity concentrations of the measured radionuclides were determined by using a gamma-ray spectrometer (NaI-Tl-activated detector). The mean (238U), (232Th), and (40K) concentrations in the studied rocks were found to be 3680.3, 3635.2, and 822.76 Bq/kg, respectively. The contents in these rocks were elevated, reaching up to 6.3 wt%. This indicated the alkaline nature of these rocks. The high ratios of Th/U in the mineralized rocks could be related to late magmatic mineralization, suggesting the ascent of late magmatic fluids through weak planes such as faults and the contact of these rocks with older granites. The present data were higher than those of the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) guideline limits. All the radiological hazard results indicated high human health risks. This confirmed that this area is not radiologically safe, and care must be taken when working in this area. This study showed that the area under investigation had high U content suitable for uranium extraction that could be used in the nuclear fuel cycle.
