“…Consistent field sampling, chemical, and physical analysis protocols were developed across the NASGLP (Friske et al 2013b(Friske et al , 2014. Pilot studies comprising two continental-scale transects across the United States and Canada were carried out to guide the development of these protocols.…”

“…In Canada, systematic sampling under the NASGLP was conducted by the GSC, provincial Geological Surveys, and soil scientists from Agriculture and Agri-Food Canada (AAFC). Field sampling began in 2007 throughout the Maritime Provinces (New Brunswick, Nova Scotia, and Prince Edward Island) and further field sampling occurred during 2008 and 2009 across the remaining provinces (Grunsky et al 2013;Friske et al 2014). Sampling was completed in the Maritime Provinces; however, only a limited number of sites were sampled in the other provinces (Newfoundland, Quebec, Ontario, Manitoba, Saskatchewan, Alberta, and British Columbia), owing to changing priorities in GSC (Friske et al 2013b).…”

“…Field sampling comprised excavating a 60 cm wide by 70 cm long soil pit at each site (Friske et al 2014). Soil samples were collected from the Public Health layer (0 to 5 cm), 0 to 30 cm (2009 field season only), and the A, B, and C horizons.…”

“…Organic matter was estimated by loss on ignition (LOI) at 500 °C (Friske et al 2013b). Particle size analysis for grain size greater than 63 µm was determined by wet sieving, and grain size less than 63 µm was determined using a Lecotrac LT-100 particle size analyser (Friske et al 2014). Further details on sampling procedures are described by GSC (Open Files 6433, 7334) and the USGS (Open File 2005-1253).…”

Soil plays a crucial role in ecosystem functioning, e.g., soil minerals provide important provisioning and regulating ecosystem services. The determination of soil mineral composition can help to link geochemical processes to underlying bedrock and surficial geology, however analysing quantitative soil mineralogy by X-ray diffraction can be expensive. This study used data from the North American Soil Geochemical Landscapes Project sampled at sites (n = 560) across Canada; exploratory analysis of major elements from the C-horizon, < 2 mm size fraction, was carried out to determine whether geochemical data can infer site-specific qualitative soil minerals. Results for the raw geochemical data indicated relative variability of major elements across Canadian provinces with noticeable differences for silica and calcium. Geochemical data are compositional, and as such their statistical assessment is subject to the problem of closure. In the current study, all raw geochemical data were centred log-ratio-transformed prior to statistical analysis to overcome closure. Graphical measures indicated skewed element data prior to centred log-ratio transformation, which produced a more symmetric distribution. Correlations between elements suggested tentative soil mineral composition, such as silica and aluminum from aluminosilicates minerals. Principal component analysis of transformed geochemical data revealed three distinct groups of calcium, magnesium; iron, titanium, manganese; and aluminum, potassium, silica, sodium, while phosphorus had smaller relative variability independent of these groups. The interpretation of these groups was based on soil minerals and identified as carbonates, silicates, and weathered secondary oxides. These minerals corresponded geospatially

The presence of radon in soil poses a significant health risk when it enters and concentrates indoors. The primary health problem associated with radon exposure is lung cancer, but it can also contribute to other respiratory issues. Estimating radon potential is a challenging task caused by the interaction of various environmental, geological, and variability factors. Although efforts are ongoing to improve radon potential assessment methodologies, there is a lack of software tools that estimate and model radon potential in different scenarios. The paper aims to develop a novel web-based software tool, RadonPotential, that predicts Geogenic Radon Potential by considering variations in climate and soil textures.The program runs using a constant radon concentration or estimates its concentration from the radium activity. RadonPotential calculates the transport of radon through a soil profile based on water content and soil texture. It also determines the dynamics of soil water content in different climates, incorporating long-term weather data under various climatic scenarios and local weather time series. The web-based format of the program increases its dissemination, usage, and manageability among a larger user base compared to an installable computer program. The program aims to provide a simplified and effective characterization of radon potential levels accessible to a wide range of scientists, technical experts and policymakers in developing strategies not only for radon measurement and mitigation buildings but also for developing more reliable large-scale radon potential maps.

Based on ground gamma ray spectrometry surveys conducted from 2007 to 2010 in populated areas across Canada (i.e. in southern Canada, excluding the northern territories), and with considerations of the exposure outdoors and indoors in various types of buildings as well as exposure to radionuclides in building materials (assuming most building materials are of local origin), the population-weighted annual effective dose from exposure to terrestrial gamma rays was estimated to be 167 ± 43 μSv. Under Canadian-specific average occupancy times, indoor exposures at home contribute 69% of the total annual effective dose, followed by 19% from indoor exposures other than at home, 6.2% from outdoor exposures and 5.8% from exposures inside vehicles. This assessment with measurements in a total of 1057 sites in populated areas across Canada is in general agreement with earlier assessments based on airborne gamma surveys mostly over unpopulated areas of Canada and truck-borne radiometric surveys along paved urban roads in four cities.
