“…The process of radon absorption in polymer materials has been studied both as a potential source of error [5] and with the goal to develop new monitors [6,7,8]. First in 1999 it was proposed to employ the remarkably high radon absorption ability of bisphenol-A based polycarbonates (trade names: Makrofol, Makrolon, Lexan etc.)…”

Simple, discriminative measurement technique for radon and thoron concentrations with a single scintillation cell Rev. Sci. Instrum. 73, 69 (2002); 10.1063/1.1416121 POINT/COUNTERPOINT: The LNT model is appropriate for the estimation of risk from low-level (less than 100 mSv/year) radiation, and Low levels of radon in homes should be considered harmful to health Med.Abstract. The report summarizes recent research and practice of using materials with high absorption ability to noble gases to measure their radioactive isotopes. Most of the studies employ bisphenol-A based polycarbonates, because of their remarkably high absorption ability to noble gases. This is the material of which commercial CDs/DVDs are made and they may serve as serendipitous, already available in dwellings, radon and thoron detectors. We present the essence of the gathered experimental evidence that the CD/DVD method can successfully address some long-lasted problems in radon dosimetry: The first is making sufficiently precise retrospective 222 Rn dosimetry for the purposes of epidemiological studies and risk estimation. The second is rapid identification of buildings with radon problem. We demonstrate how this can be used to develop an integrated approach to the radon problem. Within this approach detection, diagnostic and mitigation are considered as an unified whole, and the interval between the decision to provide disks for analysis and the complete mitigation of the building, if radon problem is identified, is short. Besides radon and thoron, bisphenol-A based polycarbonates were successfully used to measure 85 Kr and 133 Xe for the purposes of the effluents control and nuclear safety of nuclear installations. The perspectives to employ other organic materials in which noble gases are highly soluble for measurement of their radioactive isotopes are also discussed. 133 Xe both in laboratory and real conditions [9,10]. In all of these directions the "polycarbonate method" demonstrated sufficient potential for practical applications. The most prospective is the use of RADIATION PHYSICS AIP Conf. DiagnosticsIncludes source identification, routes of entry, radon distribution etc.Usually needs 1-2 weeks to perform MitigationDepending on the type and size of the building usually needs from one week to 1-2 months.

The four passive samplers (quatrefoil) already described in a parallel paper, make it possible to obtain thin radiation sources, useful for alpha and beta counting by any passive and real-time detector. In the present paper, the applications of this quatrefoil for measuring radon gas by etch-track detectors will be described. In the case of radon measurements, different solids have been identified, with radon-sorption partition coefficients related to air from 1 to 2000. Uniquely compact radon badges can be obtained by using a layer of these solids facing an alpha track-etch detector. These radon badges make it possible to overcome most of the shortcomings of existing passive monitors. Moreover, these badges show promise for studying the radon solubility of polymer films.
