“…A value of f p = 0.08 is chosen here for indoor workplaces. (A41) The value of the equilibrium factor, F , depends mainly on the indoor ventilation rate due to opening/shutting of windows, and use of electric fans, air conditioners, and dehumidifiers (Chen et al., 1998; Iimoto, 2000; Iimoto et al., 2001; Iyogi et al., 2003). Typically, mean values of F ranged from 0.3 to 0.6 for schools, kindergardens, offices, nuclear power plants, factories, and cafés (Hattori and Ishida, 1994; Hattori et al., 1995; Yu et al., 1998, 2000; Iyogi et al., 2003; Misdaq and Flata, 2003; Tokonami et al., 1996b, 2003; Misdaq and Amghar, 2005; Maged, 2006; Vaupotič, 2008b; Labidi et al., 2010). In its 2000 report, UNSCEAR assumed an F value of 0.4 for indoor exposures, based mainly on measurements in dwellings in the USA (Hopke et al., 1995) and in India (Ramachandran and Subba Ramu, 1994).…”

The 2007 Recommendations of the International Commission on Radiological Protection (ICRP, 2007) introduced changes that affect the calculation of effective dose, and implied a revision of the dose coefficients for internal exposure, published previously in the Publication 30 series (ICRP, 1979, 1980, 1981, 1988) and Publication 68 (ICRP, 1994). In addition, new data are now available that support an update of the radionuclide-specific information given in Publications 54 and 78 (ICRP, 1988a, 1997b) for the design of monitoring programmes and retrospective assessment of occupational internal doses. Provision of new biokinetic models, dose coefficients, monitoring methods, and bioassay data was performed by Committee 2, Task Group 21 on Internal Dosimetry, and Task Group 4 on Dose Calculations. A new series, the Occupational Intakes of Radionuclides (OIR) series, will replace the Publication 30 series and Publications 54, 68, and 78. OIR Part 1 has been issued (ICRP, 2015), and describes the assessment of internal occupational exposure to radionuclides, biokinetic and dosimetric models, methods of individual and workplace monitoring, and general aspects of retrospective dose assessment. OIR Part 2 (ICRP, 2016), this current publication and upcoming publications in the OIR series (Parts 4 and 5) provide data on individual elements and their radioisotopes, including information on chemical forms encountered in the workplace; a list of principal radioisotopes and their physical half-lives and decay modes; the parameter values of the reference biokinetic model; and data on monitoring techniques for the radioisotopes encountered most commonly in workplaces. Reviews of data on inhalation, ingestion, and systemic biokinetics are also provided for most of the elements. Dosimetric data provided in the printed publications of the OIR series include tables of committed effective dose per intake (Sv Bq−1 intake) for inhalation and ingestion, tables of committed effective dose per content (Sv Bq−1 measurement) for inhalation, and graphs of retention and excretion data per Bq intake for inhalation. These data are provided for all absorption types and for the most common isotope(s) of each element. The electronic annex that accompanies the OIR series of publications contains a comprehensive set of committed effective and equivalent dose coefficients, committed effective dose per content functions, and reference bioassay functions. Data are provided for inhalation, ingestion, and direct input to blood. This third publication in the series provides the above data for the following elements: ruthenium (Ru), antimony (Sb), tellurium (Te), iodine (I), caesium (Cs), barium (Ba), iridium (Ir), lead (Pb), bismuth (Bi), polonium (Po), radon (Rn), radium (Ra), thorium (Th), and uranium (U).

“…Then, the nuclear track detectors were collected and sent to the Dosirad laboratory (France) for etching and reading. Different calibrations are used for each set of the open and closed detectors to estimate the radon concentration levels as well as to calculate the equilibrium factors between radon and its progeny (Labidi et al, 2010). …”

Indoor radon concentrations were measured in four well-known spas of Tunisia using nuclear track detectors. The radon concentrations in these spas were found to be in the range of 19 − 870 Bq.m -3 . The equilibrium factor F between radon and its progeny was found to vary in the range of 0.2 -0.5, depending upon the ventilation rates within the buildings of the spas. Using the exposure-dose conversion factor, the effective doses to patients and workers were estimated and the dose was found to vary in the range 3.7 × 10 -3 − 12.5 × 10 -3 mSv.y -1 and 0.45 − 1.5 mSv.y -1 for patients and workers, respectively. These values are well inside the limit recommended for the annual dose limit of 20 mSv.y -1 for an occupational worker. The radium content in the groundwater of all four spas was measured and the results showed no correlation between the 226 Ra concentration in water and radon concentration in indoor air of the investigated spas.
