Assessment of Seasonal Radon Concentration in Dwellings in Erzurum Province of Türkiye | Chapter 8 | Current Perspective to Physical Science Research Vol. 9

The increasing awareness concerning radon (222Rn) health hazards on organic structures obligates researchers to investigate the sources and impacts within the environment. Indoor radon measurements were carried out in dwellings in Erzurum province during the winter months of February 2012 to early April 2012 and the summer months of July 2012 to early September 2012. A nuclear track detector LR-115 was used for the measurements. According to the results of investigations, it was understood that the indoor radon concentration averages in dwellings are in the range of 11 ± 6 Bq m3 - 380 ± 91 Bq/m3 in the winter season and 8 ± 3 Bq/m3 - 356 ± 64 Bq/m3 in the summer season. We found that the 222Rn effective dose values in the studied dwellings in the winter season range from 0.278 to 9.59 mSv/y. Also, the 222Rn effective dose values in the studied dwellings in the summer season range from 0.202 to 8.98 mSv/y. These values are within the ICRP recommended values. The radon activity has not been found to vary with seasonal changes, but also with the age, the construction mode of houses, the ventilation conditions and with specific sites and geological materials.

Evaluation of Complex Antioxidant Systems and the Hormesis Effect of Radon in Experimental Studies on Rats of the Krushinsky-Molotk Line | Chapter 1 | Current Innovations in Medicine and Medical Science Vol. 6

 The current study is the first to attempt R-Ho breathing for the treatment of epileptic seizures in animal models, accompanying further translation to dispassionate trials in persons via a ship phase II study. According to our judgments, radon inhalation in exploratory animals, specifically in genetically driven rats with epileptic seizures, altered all limits of the epileptic seizure growth picture, including the secret period and the event of the first and second wild jogs later the audiogenic signal. On the third epoch, there was no answer to the audiogenic signal and not a single scene of tonic-clonic seizures. All of the same indicate that radon breathing could be used to treat muscle spasm. More profound and accurately systematised approaches are required to decide the uniqueness of Tskhaltubo water springs, in addition to extensive research into the machines of radon effects on the excitatory and inhibitory functions of the CNS, in addition to additional dispassionate studies to establish its effect on persons. However, based on the results of the experiment, it maybe concluded that studies transported on experimental mammals have shown that the wonder of hormesis develops when water is inhaled from a water,  that regulates oxidative processes in the intelligence by activating antioxidants, that is manifested apiece reduction of existent epileptic seizures and is manifested in determinable changes in  activation, Na / K-ATPase and particular glutaminergic neurons of the "attack center" of the hypothalamus. Inhalation of Tskhaltubo water can be thought-out as a method of situation with an anticonvulsant effect substantiated by experimental studies.

Estimation of Annual Effective Dose Due to Ingestion and Inhalation of Radon in Groundwater from Kaduna, Nigeria: Recent Development | Chapter 11 | Theory and Applications of Physical Science Vol. 4

The variation in the concentration of radon in groundwater sources comprising of boreholes and wells in Kaduna metropolis and environs were determined by using Tri-carb LSA 1000 liquid scintillation counter. The radiation dose received by individuals within different age groups categorized under; infants, children and adults, depending on their average annual water consumption rates (ACRs) were also estimated. The mean radon activity in 16 boreholes and 18 well water samples were 1.8/Bq/L and 0.57 Bq/L respectively; while the average radon activities ranged from 0.85 to 2.57 Bq/L and 0.35 to 0.85Bq/L respectively with all values far below the United States Environmental Protection Agency MCL of 11.1 Bq/L. All the estimated annual committed effective dose (ACED) for all samples were observed to increase with radon concentration, age and ACRs, but were significantly lower than the United Nation Scientific Committee on Effect of Atomic Radiation (UNSCEAR) and World Health Organization (WHO) recommended limit of 1mSv/yr. The radiation dose rate received by the lung cells due to the inhalation of waterborne radon in the air was considerably higher when compared to that received by the stomach walls via ingestion.
