Forty-eight soil profiles down to a depth of 40 cm were taken in Russia and Ukraine in 1995 and 1997, respectively, in order to investigate the feasibility of retrospective dosimetry of the 131I exposure after the Chernobyl accident via the long-lived 129I. The sampling sites covered areas almost not affected by fallout from the Chernobyl accident such as Moscow/Russia and the Zhitomir district...

Background: An amount of artificial radionuclide has been released into the environment as fallout, resulting from atmospheric nuclear weapon tests, nuclear accidents such as Chernobyl and together with air currents have polluted the world. Materials and Methods: 37 surface soil samples of Tehran province were collected in the period between June and September 2008, by implementing met...

With the integration of the KEGG and Predictome databases as well as two search engines for coexpressed genes/proteins using data sets obtained from the Stanford Microarray Database (SMD) and Gene Expression Omnibus (GEO) database, VisANT 3.0 supports exploratory pathway analysis, which includes multi-scale visualization of multiple pathways, editing and annotating pathways using a KEGG compati...

Effects of low-level radiation on abundance of animals are poorly known. We conducted standardized point counts and line transects of bumble-bees, butterflies, grasshoppers, dragonflies and spider webs at forest sites around Chernobyl differing in background radiation by over four orders of magnitude. Abundance of invertebrates decreased with increasing radiation, even after controlling for fac...

Results of epidemiological studies of thyroid cancer incidence in Russia following the Chernobyl accident are presented in the article. Child population in territories contaminated with radionuclides who got thyroid dose from incorporated (131)I above 100-150 mGy, should be referred to a group at radiation risk. Prognostic estimates of increase in thyroid cancer incidence among the population l...

Thirty five years ago, the All-Union Distributed Registry of Persons Exposed to Radiation as a re-sult accident at Chernobyl Nuclear power plant (Chernobyl Registry) was created. The Computing Center Research Institute Medical Radiology USSR Academy Sci-ences (Obninsk) became core Registry. Their contribution creation registry made by all former Soviet republics. Currently, is called National a...

A cytogenetic study was carried out on 359 clean-up workers who worked at the Chernobyl station in 1986-1989. The investigation was performed 6-12 years after irradiation. Chromosome type damages, i.e. double fragments, dicentrics and rings were significantly increased in the cleanup workers compared to the control. Chromatid exchanges were found only in the clean-up workers. A temporal change ...
