Radon is a carcinogenic, radioactive gas that can accumulate indoors and undetected by human senses. Therefore, accurate knowledge of indoor radon concentration crucial for assessing radon-related health effects or identifying radon-prone areas.
We present a petrographic, petrological, geochemical, and geochronological study (U–Pb/Lu–Hf) on granulite-facies paragneisses of the Mahamba Gneiss Complex in central Swaziland, eastern Kaapvaal Craton. Our data suggest that prograde metamorphism occurred at c . 3.07 Ga. Dating detrital zircons metapelite combination with ambiguous structural relationships granitoid gneisses suggests two possible scenarios: (1) time deposition sedimentary protoliths is prior to 3.58 Ga; (2) Ga crust was...
The presence of excess 234 U in seawater is a compelling argument for active delivery solutes from the continents to oceans.Previous studies found, however, that complementary deficit on surprisingly modest, which would require protracted loss large continental weathering pool.Our new compilation and statistical analysis published data, coupled with mass balance calculation demonstrates apparent small pool implied by previous insufficient observed oceanic excess.Our data saprolite profile...
Abstract Essential trace metals are well known for their environmental toxicity and being part of complex bio-chemical cycles. Their role as critical micronutrients, delivering vital health benefits, is less widely discussed understood, holding back strategies combatting malnutrition. Crops grown on many Indian soils suffer from deficiencies in essential metals, notably iron (Fe), zinc (Zn), molybdenum (Mo). The list deficient will likely grow due to increasing future crop demand....
Accurate knowledge of indoor radon exposure is vital information for assessing radon-induced health effects, identifying prone areas or estimating the number people affected by exceedance a specific concentration in given area.Large-scale measurement campaigns are usually tool choice determining regional national exposure. These need to be representative terms all relevant factors governing (e.g., geogenic availability, distribution across floor levels, building types) providing an unbiased...
Radon is a hazardous air pollutant which can cause detriment to individuals and the society. Thus, natural consequence avoiding it or in practice, limiting exposure. This has led regulation on national international level whose objective reduction of radon In Europe, Basic Safety Standards (BSS) issued 2013, implementation mandatory for EU Member States, caused boost efforts towards as well research since number components abatement policy appeared not resolved sufficiently reliable sense...
Radon is a carcinogenic, radioactive gas that can accumulate indoors. Therefore, accurate knowledge of indoor radon concentration crucial for assessing radon-related health effects or identifying radon-prone areas. Indoor at the national scale usually estimated on basis extensive measurement campaigns. However, characteristics sample often differ from population due to large number relevant factors control such as availability geogenic floor level. Furthermore, size does not allow estimation...
