1.New buildings: how can engineers and architects predict radon levels Testing is the only way to know a building’s radon levels. At present, there are no reliable, easily applied and inexpensive methods that could conclusively identify problem sites and predict if a new building will have high indoor radon levels. There are a lot of factors that cause elevated indoor radon ...

Water samples collected from different sources were analysed for radon concentrations in order to evaluate the health effect associated with radon in water. The radon concentrations were in the range of 3.56–98.57, 0.88–25.49, 0.73–1.35 and 0.24–1.03 Bq.L−1 for borehole, well, packaged and utility water, respectively. Samples from boreholes had the highest radon concentrations with about 67% ...

Submarine groundwater discharge is a process that is often considered negligible in deltaic systems given their low gradient and fine-grained sediment. However, hydrologic budgets and radon surveys indicate that it may be a significant component of the Mississippi River Delta system. To more concretely indicate groundwater's contribution to the local environment, we conducted an analysis of ...

In today’s world where every property is subject to potential environmental risks a Phase 1 Environmental Site Assessment or ESA is an appropriate action to take. An ESA can help determine if the property has been contaminated by previous or current activities. The ESA can help protect the purchaser of a property from environmental risks prior to the closing on a property.  Lenders ...

In the present work, radon concentration was measured for different types of bottled drinking water and carbonated drink samples that are available in Iraqi markets. Radon measurements were carried out using a RAD-7 electronic radon detector. Annual effective dose was also calculated. The measured radon concentration in samples of bottled drinking water ranged from 0.0354 to 0.248 Bq/l with a ...

The indoor radon gas released from concrete was measured using a 0.65 × 0.65 × 0.65 m fabricated concrete slab room, simulating a workplace. The indoor radon gas concentration was monitored, and the remediation method was examined. Radon concentrations were monitored using Radon Monitor Model 1023 from Sun Nuclear. Results show that average radon concentrations reached 111 ...

I was called recently by a concerned parent. His school was undergoing mold remediation during school hours. Also, the Shigella bacterium has closed several schools in the Birmingham area. Just how safe are your children in their school, and how can you help to ensure that they are in a safe environment? By being proactive and asking questions. The biggest problems regarding ...

January is National Radon Action Month and the EPA and the U.S. Surgeon General are urging all Americans to take action and protect their health by testing their homes, businesses, schools and other buildings for radon. Radon is impossible to detect by humans as you can’t see, smell or taste it but it is the leading cause of lung cancer deaths among nonsmokers in America claiming the lives ...

The simulations of hourly 222Rn concentrations are performed with the EMEP model to validate different parameterization schemes for vertical mixing. In addition to recently evaluated non–local vertical diffusion schemes, a new scheme which is a local and based on total turbulent energy (TTE) has been implemented in the model and evaluated. Due to its properties 222Rn is commonly used ...

A simple and easy to use radon calibration chamber of volume of 216 litres was designed and constructed for applications in calibration of radon measuring devices and for research studies. The main advantage of this chamber is that instead of using 226Ra source to generate the 222Rn inside the chamber, ...

Indoor radon studies have been carried out in 100 dwellings of 20 villages in western districts of Haryana, India, using the solid–state nuclear track detector technique. LR–115 Type II films in the bare mode were exposed for 1 year on a quarterly basis to cover all the four seasons for the measurement of indoor radon levels. The annual average indoor radon concentration in the study area varies ...

Ankylosing Spondylitis (AS) is a rheumatic disease and almost 50% of the affected patients suffer from osteoporosis. The ratio of Receptor Activator of Nuclear Factor κB Ligand (RANKL) and Osteoprotegerin (OPG) has become an important marker to assess the status of systemic bone metabolism and has been shown to be dysregulated in AS patients. Combined Low-Dose Radon- and Hyperthermia Therapy ...

Naturally occurring radioactive elements are found in all groundwaters, especially in bedrock waters. Exposure to these radioactive elements increases the risk of cancer. The most significant of these elements is radon which, as a gas, is mobile and dissolves in groundwater. In Finland, water supply plants are obliged to carry out statutory monitoring of the water quality, including radon. ...
