background: two of the important radionuclides which are entered to environment and human diet are radium-226 (226ra) and cesium-137 (137cs). it is clear that the methods for preparation of foods such as peeling, washing, cooking or frying can affect the dose which is received by human due the to consumption of foodstuffs. an experiment has been performed at the environmental monitoring section...

The activity concentrations of 226Ra, 232Th, 40K and 137Cs in water and sediment samples from hot springs of Mahallat and  soil samples from their neighboring environs  have been determined using two high resolution high purity germanium (HPGe) detectors with relative efficiencies 38.5% and 55%. The activity concentrations of 226Ra, 23...

BACKGROUND Six years of recent ongoing economic and structural crisis in Croatia have brought to a significant decrease of socioeconomic standard in our country, and had an important impact on the health care system. In this background we examined the prevalence of depression and burnout and their association with work stressors. SUBJECTS AND METHODS Cross sectional survey was conducted with ...

High-Z nano materials have been previously shown to increase the amount of dose deposition within the tumour due to an increase in secondary electrons. This study evaluates the effects of high-Z nano materials in combination with protons, and the impact of proton energy, nanoparticle material and concentration. These effects were studied in silico through Monte Carlo simulation and experimental...

Acoustic-reflex growth functions (ARGFs) were obtained from 20 normal-hearing listeners. Contralateral acoustic reflexes (ARs) were elicited with pure tones of 2000 Hz. The magnitude of changes in static compliant susceptance (BA) and conductance (GA) were monitored with probe-tone frequencies of 226 Hz, 678 Hz and 1000 Hz. ARGFs were obtained with six combinations of probe-tone frequency/admit...

Background: One of the most significant radionuclides in natural drinking waters is 226Ra and its decay products. It is potential of health problems, including cancer risk. In this study, the effect of 226Ra concentration in 28 drinking water samples collected from the North Guilan province was investigated. Materials and Methods: The activity concentrations of 226Ra were measured by using of r...
