EPR dosimetry intercomparison using smart phone touch screen glass
2014
International audience; This paper presents the results of an interlaboratory comparison of retrospective dosimetry using the electron paramagnetic resonance method. The test material used in this exercise was glass coming from the touch screens of smart phones that might be used as fortuitous dosimeters in a large-scale radiological incident. There were 13 participants to whom samples were dispatched, and 11 laboratories reported results. The participants received five calibration samples (0, 0.8, 2, 4, and 10 Gy) and four blindly irradiated samples (0, 0.9, 1.3, and 3.3 Gy). Participants were divided into two groups: for group A (formed by three participants), samples came from a homogene…
Toxic impact of the de-icing material to street greenery in Riga, Latvia
2008
Abstract There is little information on the ecological composition of snow on roads as well as the toxic effect of de-icing salt on the ecological status of the street trees ( Tilia x vulgaris H.) in Latvia. Tilia x vulgaris is one of the most widespread tree species of street greenery in the boreo-nemoral zone – in Central, Northern and Eastern Europe. This investigation was done to find out the accumulation of de-icing salt (main elements – sodium and chlorine) in the snow–soil–plant system of street greenery in the central part of Riga (2004–2005), in order to reveal the toxic effect on the ecological status of the street trees ( Tilia x vulgaris ). Snow, soil and leaf samples were colle…
Prevalence of burnout in Polish anesthesiologists and anesthetist nursing professionals: A comparative non-randomized cross-sectional study.
2015
The purpose of the study was to assess the burnout levels in nurses ( N = 161) versus physicians ( N = 373). The levels of burnout were evaluated by the Polish adaptation of the Spanish Burnout Inventory (Cronbach’s alpha > .70). High burnout level was found in 18.63 percent nurses and 12.06 percent anesthesiologists, and critical level in 3.74 percent nurses and 5.90 percent anesthetists. There were statistically significant differences in Burnout global score, Enthusiasm toward the job, Psychological exhaustion, and Indolence subscales between nurses and physicians. No significant differences were found between sexes in any variable.
