High radon levels in a Minnesota (USA) basement with a passive under slab vent pipe system can be seen in the left half of the graph. After installation of a radon fan (ASD), a permanent reduction in radon levels to approximately 0.6 pCi/L can be seen in the right half of the graph. The most common approach is active soil depressurization (ASD).
Radon is also oxidised by dioxygen difluoride to RnF 2 at 173 K (−100 °C; −148 °F). [25] Radon oxides are among the few other reported compounds of radon; [29] only the trioxide (RnO 3) has been confirmed. [30] The higher fluorides RnF 4 and RnF 6 have been claimed [30] and are calculated to be stable, [31] but their identification is ...
Radon is responsible for the majority of public exposure to ionizing radiation. It is often the single largest contributor to an individual's background radiation dose, and is the most variable from location to location. Radon gas from natural sources can accumulate in buildings, especially in confined areas such as attics and basements.
The membrane is tested immediately after installation and prior to being covered up by any following construction processes. The area below the membrane is temporarily pressurized with a mixture of clean air and a non-toxic and inert tracer gas that is sensitive to detection. Special equipment is then used to trace all leaks within the ...
The public needs to be aware of radon risks and the means to reduce and prevent these." [2] In 1996 [citation needed], WHO published a report containing several conclusions and recommendations covering the scientific understanding of radon risk and the need for countries to take action in the areas of risk management and risk communication.
Paws and Claws: Pet Vet is a pet-raising simulation video game by German studio Radon Labs in which players can nurse dogs, cats, horses, birds, hamsters, guinea pigs and rabbits back to health. The game features 20 ailments.
This allowed the creation of organizations like the humane society and the Society for the Prevention of Cruelty to Animals (SPCA), which have set standards of care for dogs that live outdoors including a properly designed doghouse that is structurally sound, weatherproof, insulated, of adequate size and appropriate for the dog's use, at all ...
NanoH2O Inc. commercialized a membrane in which zeolite nanoparticles were synthesized and embedded within an RO membrane to form a thin-film nanocomposite, or TFN, which has proven to be more than 50-100% more permeable compared to conventional RO membranes while maintaining the same level of salt rejection.
