To study the heart rate variability (HRV) in bronchial asthma (BA) examined 107 children aged 10 to 18 years old with asthma exacerbation. As a result of the application of asthma control test (GINA, 2011) on the level of controlled asthma children were distributed as follows: 34 (31.8%)--with controlled (CBA), 47 (43.

Doses from the ingestion of 134Cs and 137Cs during 12 y following the Chernobyl accident have been estimated for approximately 3 million persons living in rural areas of the Zhitomir, Rivne, and Kyiv Oblasts of northern Ukraine. This assessment is based upon an extensive monitoring campaign that provided measurements of 137Cs in more than 120,000 samples of milk and in more than 100,000 persons; such measurements were made in approximately 4,500 locations. Two approaches were used for the dose assessment.

The Chernobyl accident, which occurred in April 1986, resulted in the atmospheric release of about 70--100 PBq of 137Cs. This paper examines the doses to the adult population of the northern part of Rovno Oblast, Ukraine, from ingestion of 137Cs. Fallout of 137Cs in these regions was lower than in other regions of Ukraine.

The problem of post-Chernobyl dosimetry is unique in its complexity in the history of radiation medicine and radiation protection. This is because the early experience of mass exposure of people (bombing of Hiroshima and Nagasaki, Windscale and South-Ural accidents, exposure of inhabitants of Nevada in the United States of America, the Semipalatinsk area in the former USSR, the Marshall Islands, and the Goiånia accident in Brazil, and others) differed both in the much simpler structure of the irradiation source and in the number and characteristics of exposed persons. It is obvious that post-Chernobyl dosimetry, both as an independent problem, and as a tool for epidemiological studies, requires significant expertise and economic and technical expenditures.

Out of 106 firemen who had been engaged in extinguishing fire at Chernobyl NPP in October 11-12, 1991, 39 were examined immediately on the spot and 67--in out-patient department of the Ukrainian Scientific Research Centre of Radiation Medicine. Examination included anamnestic inquest, peripheral blood study and determination of incorporated irradiation. Besides this, about 50 measurements of exposure dose were carried out in the town of Chernobyl, in the NPP territory and in immediate proximity to the site of the accident.
