Radon progeny aerosol control device and related ... - Springer
Jan 4, 2024 · By studying the mechanism of radon progeny aerosol and establishing a radon progeny aerosol control device that meets the measurement standards, the concentration of radon progeny aerosol in a radioactive aerosol monitor in certain places can be corrected.
iCAM™ Mobile Alpha Beta Particulate Monitor | Mirion
The iCAM measures airborne alpha and beta particulate activity with dynamic radon/thoron alpha and beta background compensation. It also provides static or dynamic compensation of beta measurements for gamma background depending on the choice of detector type.

Radon progeny measurements in a ventilated filter system to …
Jul 4, 2023 · Here, we use gamma spectroscopy to measure the attachment of radon progeny on an air-ventilated filter system within a radon enriched atmosphere, mimicking the respiratory tract.
In this paper, numerous studies on passive techniques for radon and its progeny have been reviewed and summarized. The mainstream of passive devices can be classified into four groups: (i) alpha track detectors, (ii) activated charcoal detectors, (iii) electret ion chambers, and (iv) thermo-luminescent dosimeters.
ADGEO - Portable two-filter dual-flow-loop 222Rn detector: stand …
In principle, two-filter dual flow-loop radon detectors operate as follows: ambient aerosols, radon progeny and thoron (220 Rn) are removed from the sampled air, which then passes directly into a delay chamber as part of the first flow loop (the “external” or sampling flow loop). New radon progeny form in the delay chamber under relatively ...
Breakthrough on radon individual monitoring and protecting
Nov 27, 2023 · Breakthrough is made on inventing, producing and applying novel dual-function passive individual radon monitor in canister on respirators for radon inhalation monitoring and protecting...
5 Best Radon Detectors - Dec. 2024 - BestReviews
Apr 26, 2022 · Since humans cannot sense radon, the only way to know for certain if your home is safe is to get a radon detector. A radon detector either continually monitors your home’s air for radon or collects radon data for later analysis.
Intercomparison study of atmospheric 222Rn and 222Rn …
The use of the noble gas radon (222Rn) as a tracer for different research studies, for example observation-based estimation of greenhouse gas (GHG) fluxes, has led to the need of high-quality 222Rn activity concentration observations with high spatial and temporal resolution.
A novel method for simultaneous measurement of
18 hours ago · Considering that the relative uncertainty of the detection efficiency \(\sigma _{{E}}/E\) is ± 2.0%, the relative uncertainty of the flow rate \(\sigma _{{Q}}/Q\) is ± 3.0%, and the statistical uncertainty, relative uncertainty of radon progeny concentrations provided by the new methods are all within ± 16%, and those of the thoron progeny ...
