annual average absolute humidity (hP a).
Attempting to further describe the thermohygrometric variations along the year, mean values of absolute humidity (AH) are also depicted in Figure 13.
The water consumption was 10.1 ± 1.6 mg/l inspired air (mean ± standard deviation) and the absolute humidity in the expiratory ventilator tubing was 7.5 ± 2.2 mg/l (mean ± standard deviation).
Variables included monthly means (long-term averages) of absolute humidity, absorbing aerosols (dust) and rainfall, and land-surface maps of land-cover type and population density (Table 1).
From our assumed values of absolute humidity (calculated from monthly mean RH and air temperature in Fukushima City11), breathing rate (20 m3/d), and dose conversion factor ICRP-72166), westimatethethe committed effective dose (CED) from HTO inhalation to be 3 μSv.
Weekly mean vapor pressure was calculated as a metric for absolute humidity following an equation provided by Basu et al. [ 18], (1) vapor pressure = 0.0 6112 * relative humidity % * 1 0 7. 5 * temperature (° C ) / (237. 7 + temperature (° C ) ) Vapor pressure will be used for absolute humidity hereafter in this paper.
aMean monthly climate averages (1961 1990) for absolute humidity and rainfall (the former derived from vapor pressure and mean temperature) were obtained from the Climate Research Unit, University of East Anglia, UK (available from: URL: http://ipcc-ddc.cru.uea.ac.uk/).
The absolute humidity in the inspiratory ventilator tubing was 0.14 ± 0.15 mg/l (mean ± standard deviation).
(c) Daily relative humidity calculated on the basis of summing hourly absolute humidity (RH') as a function of daily average relative humidity for the period 1949 2010.
These values comprised the most common seasonal profile class for each variable (absolute humidity, dust, and rainfall), the most common land-cover type, and the geometric mean population density.
Another study revealed that hygroscopic hydrophobic HMEs attained similar absolute humidity levels when used for 24 or 48 hours, with no increase in mean airway pressures at 48 hours [ 58].
