INDOOR RADON, THORON AND THEIR PROGENY CONCENTRATIONS IN HIGH THORON RURAL SERBIA ENVIRONMENTS [PDF]

Radiation Protection Dosimetry, 2017
This article deals with the variation of radon (Rn), thoron (Tn) and their progeny concentrations expressed in terms of equilibrium equivalent concentrations (EERC and EETC), in 40 houses, in four villages of Sokobanja municipality, Southern Serbia. Two types of passive detectors were used: (1) discriminative radon-thoron detector for simultaneous Rn ...

Cellular mechanisms of radiation‐induced myocyte dysfunction: effects on calcium handling, ion channel regulation and mitochondrial energetics

The Journal of Physiology, EarlyView.
Abstract figure legend Dose‐dependent effects of radiation on cardiac electrophysiology and arrhythmia susceptibility. At low radiation doses (left), increased reactive oxygen species (ROS) initiate an ROS–Ca2+ positive feedback loop involving calcium/calmodulin‐dependent protein kinase II (CaMKII) activation, enhanced L‐type Ca2+ current (ICaL ...

Back to Basics: Increasing Tiredness and Hunger in Nordic Classrooms and Their Links to Disorderly Behaviour and Academic Achievement

European Journal of Education, Volume 61, Issue 2, June 2026.
ABSTRACT This study examines trends in self‐reported tiredness and hunger among 4th grade students in the Nordic countries between 2016 and 2023, using data from PIRLS and TIMSS. Results show a significant increase in the proportion of students who frequently arrive at school feeling tired or hungry, with tiredness reported by 38%–52% of students and ...
