THE INFLUENCE OF THE EQUILIBRIUM FACTOR ON THE ESTIMATED ANNUAL EFFECTIVE DOSE FROM INHALED RADON DECAY PRODUCTS IN SELECTED WORKPLACES.

Measurements of activity concentration of radon gas and radon decay products were carried out in several workplaces including schools, radium spas, swimming pools, water treatment plants, caves and former mines. Based on these measurements, annual effective doses to workers were estimated and values of the equilibrium factor, F, were calculated. This paper describes the different approaches used to estimate the annual effective dose based on the dose coefficients recommended by the International Commission on Radiological Protection.

Diagnostic Dilemma of Recurrent Pulmonary Embolism.

Popliteal venous aneurysms are rare vascular disorders associated with a high risk of pulmonary embolism. We present the case of a 56-year-old woman hospitalized for a third episode of unprovoked pulmonary embolism. Venous ultrasonography identified a popliteal aneurysm, repeatedly missed by two-point compression venous ultrasonography, which was eventually confirmed by a magnetic resonance examination.

Comparison of two different treatments in depressed pregnant women: fetal growth characteristics and neonatal outcomes.

Background In this pilot study, the effects of selective serotonin reuptake inhibitors (SSRIs) and psychological intervention on fetal growth characteristics and neonatal outcomes were evaluated in two different groups of women affected by prenatal depression. Methods Forty-seven pregnant women diagnosed with major depression were divided into two different treatment groups according to the severity of their depression. The first group was treated with a combination of pharmacotherapy and psychological support.

Simultaneous Measurements of Nanoaerosols and Radioactive Aerosols Containing the Short-lived Radon Isotopes.

The activity size distribution of the Equilibrium-Equivalent Concentration (EER) of 222Rn is one of the most important parameters for the estimation of radiation dose by inhalation of radon decay products. A series of measurements of the EER activity size distribution were performed by the screen diffusion battery in Radon-Aerosol chamber (10 m3) at the National Institute for Nuclear, Chemical, and Biological Protection (SUJCHBO). These measurements were performed at different levels of radon concentration.
