“…Given the diversity of the underlying geologies, climates, and building portfolios (housing ages, designs, etc.) across Canada, the consistency of the higher rural radon effect was striking, reflects trends observed internationally 37,[52][53][54][55][56][57] , and suggests a common cause.…”

Repetitive, long-term inhalation of radioactive radon gas is one of the leading causes of lung cancer, with exposure differences being a function of geographic location, built environment, personal demographics, activity patterns, and decision-making. Here, we examine radon exposure disparities across the urban-to-rural landscape, based on 42,051 Canadian residential properties in 2034 distinct communities. People living in rural, lower population density communities experience as much as 31.2% greater average residential radon levels relative to urban equivalents, equating to an additional 26.7 Bq/m3 excess in geometric mean indoor air radon, and an additional 1 mSv/year in excess alpha radiation exposure dose rate to the lungs for occupants. Pairwise and multivariate analyses indicate that community-based radon exposure disparities are, in part, explained by increased prevalence of larger floorplan bungalows in rural areas, but that a majority of the effect is attributed to proximity to, but not water use from, drilled groundwater wells. We propose that unintended radon gas migration in the annulus of drilled groundwater wells provides radon migration pathways from the deeper subsurface into near-surface materials. Our findings highlight a previously under-appreciated determinant of radon-induced lung cancer risk, and support a need for targeted radon testing and reduction in rural communities.

“…For instance, the concentration in the study area exceeded that of Peshawar 43 , Agbabu, Nigeria 28 , Makkah, Saudi Arabia 46 , Penang, Malaysia 27 , Mirpur 31 , and Rajasthan. 12 On the other hand, it was lower than the concentrations found in Bannu 32 , Gilgit 9 , and Nigeria 47 . A comparison of the 222 Rn concentration in the study area's drinking water with data from previous studies conducted in various regions and countries is presented in Table 1 .…”

“…The quantity of 222 Rn in the underground water is initiated by the existing environmental conditions. When using water for domestic purposes, it is most probable to be exposed to 222 Rn 11 , 12 . There are two potential routes through which individuals can come into contact with 222 Rn in water: either by consuming water that has been contaminated or by inhaling the 222 Rn that is generated from domestic water sources.…”

Geospatial methods, such as GIS and remote sensing, map radon levels, pinpoint high-risk areas and connect geological traits to radon presence. These findings direct health planning, focusing tests, mitigation, and policies where radon levels are high. Overall, geospatial analyses offer vital insights, shaping interventions and policies to reduce health risks from radon exposure. There is a formidable threat to human well-being posed by the naturally occurring carcinogenic radon (222Rn) gas due to high solubility in water. Under the current scenario, it is crucial to assess the extent of 222Rn pollution in our drinking water sources across various regions and thoroughly investigate the potential health hazards it poses. In this regard, the present study was conducted to investigate the concentration of 222Rn in groundwater samples collected from handpumps and wells and to estimate health risks associated with the consumption of 222Rn-contaminated water. For this purpose, groundwater samples (n = 30) were collected from handpumps, and wells located in the Mulazai area, District Peshawar. The RAD7 radon detector was used as per international standards to assess the concentration of 222Rn in the collected water samples. The results unveiled that the levels of 222Rn in the collected samples exceeded the acceptable thresholds set by the US Environmental Protection Agency (US-EPA) of 11.1 Bq L−1. Nevertheless, it was determined that the average annual dose was below the recommended limit of 0.1 mSv per year, as advised by both the European Union Council and the World Health Organization. In order to avoid the harmful effects of such excessive 222Rn concentrations on human health, proper ventilation and storage of water in storage reservoirs for a long time before use is recommended to lower the 222Rn concentration.

“…The Cr 6 + bioremediation potential of P. aeruginosa ATHA23 by the production of biofilm supported on clinoptilolite has been shown for the first time. Singla et al (2022) studied the concentration of radon in fifty samples of drinking waters of Hanumangarh District of Rajasthan, India, and the assessment of resulting dose to local population. The authors measured the concentration of dissolved radon using scintillation-based Smart RnDuo detector and the standard protocol recommended by BARC.…”

In the following paragraph, I will summarize the content and main results of these papers published in this Special Issue. The order of papers is based on submission date. Content and main results of the papers of this Special IssueEl-sherbeny et al. ( 2022) conducted an experiment on nitrogen fixation (NF) in an experimental farm with a drip irrigation system, at the Atomic Energy Authority, Inshas, Egypt, in order to measure the impact of efficiency symbiotic Bradyrhizobium sp. and asymbiotic Azotobacter sp. on NF, from air and soil, in the presence or absence of plant residues on the growth and yield of peanut plant. Bradyrhizobium sp. inoculation showed nearly the same levels of nitrogen derived from air (Ndfa) to those recorded with Azotobacter sp. in both the presence and absence of plant residue application through the two seasons. Results show that both possibility of NF of peanut and nitrogen uptake in the soil are enhanced by field J. Bech (*
