exposure to radon means exposure to radon progeny
The inventions provide radon-free containers for the storage and/or transport of said passive radon monitors.
risks related to radon in homes
The concentration of radon in the measuring gas is directly proportional to the concentration of radon in water when stable marginal conditions are guaranteed.
Method and apparatus for removing dissolving radon gas from waterfor the purpose of reducing the exposure of household occupants to elevated airborne radon levels.
Very small quantities of a stabilizing additive consisting of oxygen or a heavy noble gas (xenon or radon for KrF lasers, or krypton, xenon or radon for ArF lasers), are added to the gas mixture.
The second partial derivative of the Radon transform is then calculated and then the reconstructed 3-D images are obtained by backprojecting using the inverse Radon transform.
A system (10) for monitoring or controlling the level of radon in indoor air, based upon measuring alpha particles due to the decay of radon or its daughter atoms.
The detection system may be provided with first (24) and second (52) detectors for separately monitoring airborne levels of radon gas and radon decay products.
Method for detecting and measuring alpha-emitting substances, such as radon and/or daughter products of radon, by registering nuclear tracks on a detector.
In one embodiment, ihe present invention relates to a radon monitoring system (10) that is designed to remotely monitor the release of radon gas and to use such data in the prediction of earthquakes.
radon means the radionuclide Rn-222 and its progeny, as appropriate
