Optical detection of radon decay in air
An optical radon detection method is presented. Radon decay is directly measured by observing the secondary radiolumines cence light that alpha particles excite in air, and the selectivity of coincident photon detection is further enhanced with online pulse-shape analysis. The sensitivity of a demonstration device was 6.5 cps/Bq/l and the minimum detectable concentration was 12 Bq/m(3) with a 1...
متن کاملDetermination of Polycyclic Aromatic Hydrocarbons in Ambient Urban Air
Polycyclic aromatic hydrocarbons (PAHS) have been determined in the atmosphere of Isfahan, Iran. Airborne particulate matter was sampled using a high-volume air sampler at roof-top level (~6m). Extraction of PAHS from airborne particulate matter has been performed using SFE system and the relationship between the extraction temperature and the recovery of PAHS</su...
متن کاملMeasurements of Radon and Thoron Decay Products in Air. an Application of Lsc and Tld Methods
Liquid Scintillation Counting (LSC) is a measuring technique, broadly applied in environmental monitoring of different radionuclides. One of the possible applications of LSC is the measurement of radon and thoron progeny. There are certain advantages of this method, especially high counting efficiency for alpha and beta particles emitted by radon and thoron progeny. This advantage has been poin...
متن کاملLevels of nanosize radon decay products in indoor air: a comparison for different environments.
The fraction of unattached (fun) nanosized 222Rn short-lived decay products in indoor air has been measured in different environments and the following ranges obtained: 0.03-0.25 in kindergartens, 0.03-0.18 in schools, 0.08-0.20 in wineries, and 0.12-0.68 in a karst cave. The dependence of fun on the environmental conditions (air temperature, relative humidity and pressure), as well as on the w...
