Recent years have seen increased attention given to radon from two scientific directions. After neglecting as an earthquake precursor in the 1990s, it has become subject of discussions earthquake-forecast papers due growing networks monitoring different countries, particularly technologies real-time measurements where gamma spectrometers are great interest sources 222Rn identification. The second fast-developing direction involves Lithosphere–Atmosphere–Ionosphere Coupling (LAIC) models a...

An analysis of the international radon regulatory framework identified actual challenges for design and conduct indoor surveys, though there is little discussion on this issue in community. The main hindering development regulation an scale, particularly surveys include following: (i) responsibility testing mitigation, (ii) excessive focus Radon Priority Areas, (iii) role temporal uncertainty testing, (iv) standardization measurements, (v) thoron EEC measurements testing. To address these...

Among the many accumulated challenges, radon mitigation measures for existing buildings are not still carried out in Russia that, combined with use of an inadequate method indoor measurements, has led to stagnation and crisis regulation system. To overcome crisis, a ranking responsibility distribution control, including theses on updating national norms regulations ensuring radiation safety, as well nine priority activities action plan proposed accordance IAEA requirements.

Aim: To map the potential radon hazard of territories based on results sample measurements equivalent equilibrium concentration (EEC) in premises public buildings connection with analysis geological information reflected state maps at scale 1:200 000, supported by reconnaissance content natural radionuclides soil samples, using Pyatigorsk as an example. Material and methods: The EEC were used, which carried out mainly kindergartens, schools higher educational institutions city separately...

Purpose: To determine the levels of indoor radon EEC educational institutions in Lermontov city, to estimate doses due radon, establish causes increased activity concentration air and patterns its change. Material methods: measurements cold warm seasons were performed using SSNTD (TRACK-REI_1M equipment), content natural radionuclides building materials soils Progress-2000 scintillation gamma spectrometer based on NaI(Tl) detector, exhalation rate, Camera-01 charcoal complex, continuous...

The artilcle presents comments on the manuscript by A.S. Vasiliev et al. “A review of approaches to assessment potential radon hazard land plots”. does not fully reflect some features existing regulations for territories. In addition, important results modern research in field have been considered, and single science-based approach Russia assess building sites, which has implemented practice tested industry engineering environmental surveys, is ignored.

Significant temporal variations in radon are observed any buildings, including unoccupied buildings with limited ventilation. This fact causes serious difficulties radiation monitoring to assess the compliance of premises requirements normative, which limits annual average level buildings. Therefore, neither at national nor international has yet been solved problem standardizing indoor measurement if test duration is less than a year. An analysis approaches measurement, an assessment...

Abstract: Recent years demonstrate the increased attention to radon from two scientific directions. After neglecting as earthquake precursors in 1990-th it becomes again subject of earthquake-forecast papers discussions due growing networks monitoring different countries, especially, technologies real-time measurements where gamma-spectrometers become leader interest sources 222Rn identification. The second fast developing direction is including Lithosphere-Atmosphere-Ionosphere Coupling...

As a result of almost three-year observations conducted in the fault zone Beshtau magmatic massif area (Caucasian Mineral Waters), anomalous seasonal fluctuations radon exhalation rate were registered. Seasonal are characterized by highs summer and lows winter. Summer values reached 23800 mBq/(m2s), while winter decreased to 40 mBq/(m2s). Radon shows clear direct correlation with air temperature. The rise levels spring fall autumn timed moments when temperature atmospheric becomes,...

<title>Abstract</title> The article presents the results of radon release studies at rehabilitated uranium mine and an assessment doses received by population when using territory for recreational purposes (the case former Beshtaugorsky mine). measurements flux density from ground surface, concentration in atmospheric air groundwater, as well gamma dose rate content natural radionuclides soils bedrocks were performed. It is established that abnormally high associated with both a adits...

The article presents the outcomes of dead uranium mine inspection and its impact on current radiation situation in Beshtau area, as well doses to people using area a recreation land. mounting was use from 1940s 1990s. Several stages site remediation were conducted since For these purposes gamma dose rates, density radon flux ground surface products concentration atmospheric air, content natural radionuclides groundwater estimated. According measurements data it is seen that around main...

This article presents the results of long-term soil radon and meteorological parameters in fault zone at Mount Beshtau, North Caucasus, extending for more than 3 years. Strong seasonal variations levels with maxima summer minima winter were recorded. The values exhalation concentration range 0.025 - 25 Bq m 2 s -1 1 – 170 kBq -3 , respectively. To clarify mechanism transport, measurements air concentration, direction movement adits mouths former uranium mine on same mountain carried out....

This article presents the results of monitoring measurements radon concentration in air, gamma dose rate, as well velocity and direction air movement at adit mouths former Beshtaugorsky mine No.1 (Mount Beshtau). The data obtained indicate very powerful seasonal anomalies associated with periodic release from tunnels into atmosphere. During discharge, concentrations open atmosphere locally around mouth reach 594,685 Bq/m3, averaging 50000 – 250000 Bk/m3. equivalent equilibrium ranges 1600 to...

The first part of the article continues discussion with responsible regulator on actual issues radon regulation, such as (i) problem indoor mitigation, (ii) measurements and conformity assessment, (iii) public awareness responsibility for control, (iv) developing a national action plan. second will be published in next issue devoted to detailed MR 2.6.1.0333-23 terms comparison an alternative method based rational principle measurements.
