222Rn + 220Rn monitoring by alpha spectrometry
Radiation Protection Dosimetry, 2014Controlled 222Rn+220Rn mixed atmospheres have been realised introducing calibrated sources in a stainless steel chamber. An electrostatic alpha monitor internal to the chamber has been used for an accurate discrimination of alpha peaks due to the products of the two isotopes.

Modeling the Effects of Exhaust Ventilation on 222Rn Entry Rates and Indoor 222Rn Concentrations
Health Physics, 1988Continuous mechanical exhaust ventilation of moderately air-tight residences is common in Scandinavia and has recently been employed in several U.S. residences. Exhaust ventilation decreases the indoor pressure and, thus, increases the pressure difference which drives 222Rn entry. Relatively simple analytical (i.e.

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1993
Abstract A low-background ZnS scintillator cell based on a design by Lucas has been developed for 222 Rn detection. Typical cells have 63% detection efficiency and 3 counts per day background. The cells have been used in measurements of 222 Rn emanation rate into vacuum from materials to be used under water in the Sudbury Neutrino Observatory (SNO)

Recent Swedish Experiences in 222Rn Control
Health Physics, 1990Swedish local authorities are responsible for decreasing 222Rn progeny concentrations in homes in their municipalities. To obtain an overall view of their experiences, concerned national authorities sent a questionnaire in 1986 to local authorities. The results were intended to form one basis for decisions by the government regarding revised statements

Multi-state Surveys of Indoor 222Rn
Health Physics, 1989The U.S. Environmental Protection Agency provides assistance to states in conducting surveys of indoor 222Rn. Alabama, Kentucky, Tennessee, Wisconsin, and Wyoming completed statistically designed surveys during the 1986-1987 heating season. In all states, probability-based samples of 5800 houses were tested using charcoal canisters exposed for 48 h ...

Applied Radiation and Isotopes, 2006
NIST radon standards are hermetically sealed polyethylene capsules filled with 226Ra solution. Recently, four new series of standards with activities 5, 50, 500, and 5000 Bq were prepared. The measured emanation fraction agrees with a calculation that accounts for the radon accumulated inside the polyethylene walls of the capsule.

222Rn EMANATION FROM URANIUM-GLAZED CERAMICS
Health Physics, 2001Orange-red uranium-glazed dinnerware was found to emanate 222Rn to produce an average of less than 0.1 Bq 222Rn decay per piece, which should have no associated health risks. Comparison of 222Rn emanation to 226Ra in glazes (measured by alpha spectrometry) indicated inefficient emanation (

Optimum 222Rn-adsorbing Activated Charcoals
Health Physics, 1992Adsorptive and desorptive data are presented for 20 activated charcoal (AC) types that may be used in passive 222Rn sampling devices. Open-faced AC canisters were exposed for 3 d at room temperature to known radon and water vapor concentrations. Gamma measurements of radon progeny activity show that the optimum radon-adsorbing ACs are Calgon-PCB, Norit
