Comparative Study[Analysis of the late irradiation effects in the population of the north part of the East-Urals radioactive track].
Death records were used to analyze cancer mortality in the rural areas of the Kamensky District, Sverdlovsk Region, within the East-Urals radioactive track area. A study group showed a significant increase in cancer mortality as compared with a control group (65 of the 691 examinees; 90% confidence interval (CI) 18-144; the mean colonic radiation dose was 80 and 3 mGy in the study and control groups, respectively). The additional relative risk per colonic dose was 1.3 Gy(-1) (90% CI 0.36-2.9 Gy(-1)). The association of the additional relative risk with the age-related and time factors was studied and revealed.

Comparative Study[Integrated estimation of carcinogenic load on the population in the town of Aktobe].
Identification of carcinogens from the results of monitoring various environmental objects in an industrial town (Actobe) could single out 8 priority trace elements, which might cause their human accumulation. A carcinogenic risk was found to be formed due to the high ambient chromium pollution in the residential areas, to the accumulation of the elements in the deposited media and human body. Drinking water is a minor source of the identified carcinogens; therefore it may be borne in mind in the further analysis of a carcinogenic risk.

[Influence of ambient air pollution on children's health in Krivoĭ Rog].
The degree and nature of surface air pollution with man-made chemicals were studied in Krivoy Rog in 1996 to 2005. The priorities of pollutants were established in the area with different forms of technogenic emissions and residential areas. Immunological parameters were studied in healthy neonates and 7-10-year-old children. There was a reduction in the major immunological parameters in both healthy neonatal infants and 7-10-year-old children and a rise in pediatric morbidity.

Comparative Study[Impact of ambient air pollution by a pulp-and-paper mill on the cytological status of the nasal and oral mucosa in children].
The cytological state of nasal and oral mucosae in the children and adolescents living in the town of Koryazhma was evaluated at the schools located differently from the Kotlas pulp-and-paper mill (PPM). All the Kozyazhma children under examination were found to have an increased epithelocytic alteration index, which is likely to suggest cytotoxic exposure, which was shown to a greater extent with the duration of residence at the school more adjacent to the PPM. The first-form pupils from the school locates more closely to the PPM were found to showed a higher index of natural microflora colonization with buccal epitheliocytes and a trend for an increase in the epitheliocytic differentiation coefficient characterizing the high incidence of diseases.

[New wording of sanitary regulations and standards 2.2.1/2.1.1.120-03 "Control Areas and Sanitary Classification of Enterprises, Erections, and Other Projects"].
The paper gives the SanPiN requirements 2.2.1/2.1.1.120-03 "Control Areas and Sanitary Classification of Enterprises, Erections, and Other Objects" (a new wording), with emphasis on the new provisions concerning the problems associated with the determination of the size of a control area of both individual industrial projects and a group of industrial projects (industrial zones). Requirements for the evaluation of the efficiency of an established control area, by assessing the risk to human health have been first established.
