Comparative Measurements of Radon Concentration in Soil Using Passive and Active Methods in High Level Natural Radiation Area (HLNRA) of Ramsar

Journal of Biomedical Physics and Engineering, 2013
Background: Radon and its daughters are amongst the most important sources of natural exposure in the world. Soil is one of the signifcant sources of radon/thoron due to both radium and thorium so that the emanated thoron from it may cause in creased ...

Response of AlphaGUARD PQ2000 radon detector to 220Rn in diffusion mode

He jishu
Background222Rn/220Rn and their daughters are widely present in the atmosphere and indoor environment. The presence of high-concentration 220Rn can affect the accuracy of 222Rn concentration measurements.PurposeThis study aims to measure radon ...

Measurements of the deposition rates of radon daughters on indoor surfaces [PDF]

, 1983
The deposition rates of radon daughters on indoor surfaces have been measured by exposing the window of a proportional counter to the air of a house with high concentrations of radon and its daughters.

Emission and enrichments of radon daughters from Etna volcano magma

, 1976
International audienceA program of measurements in and outside the plume of Etna volcano has shown that radon daughters (as well as gaseous radon) are directly emitted from the magma. Enrichment factors have been observed: 4 for bismuth vs lead and 6 for

Introducing CdZnTe Detectors into Measuring ²²²Rn Concentrations in Water

Gases
Radon (222Rn) is a noble, radioactive gas and tends to be accumulated in poorly ventilated enclosed spaces. Mainly due to its radioactive daughters and the α-particles emitted, 222Rn poses a risk of cancer and therefore its concentration in air and water

Indoor concentrations of radon 222 and its daughters: sources, range, and environmental influences [PDF]

, 1985
The author here reviews what is presently known about factors affecting indoor concentrations of radon 222 and its daughters. In US single-family homes, radon concentrations are found to average about 1.5 pCi/1, but substantially higher concentrations ...

The particle size dependent attachment of radon daughters to a carrier aerosol.

, 1984
Most of the airborne radon-222 daughters are attached to aerosol particles. An experimental set-up for measuring the radon daughter activity as a function of the aerosol particle size is described.

Radon and Radon Daughters: Characteristics, Health Effects and Occurrences in Dwellings in Chadron, Nebraska

, 1987
Radon and radon progeny were sampled biweekly from January through June, 1984 in outside air and five representative buildings at Chadron in northwestern Nebraska. The buildings were constructed of a variety of materials. Radon averaged from a low of 0.2
