Reference values of electrographic and cardiac ultrasound parameters in Russian healthy children and adolescents
Abstract Between 2009 and 2013, a large cross-sectional study on the health consequences of the Chernobyl nuclear accident was performed in the contaminated and uncontaminated territories of the Bryansk Oblast (Russian Federation). The objective of this work was to confirm or refute a possible assoc...
