This study presents an analysis of the thyroid cancer incidence in population most contaminated territories Bryansk, Kaluga, Oryol and Tula oblasts affected by Chernobyl accident. The follow-up period is 1991-2008, cohort size 309 130 people. For that 978 cases were detected. excess relative risk per 1 Gy (ERR/Gy) found to be statistically significant for children adolescents (0-17 y age) at time accident (ERR/Gy=3.22; 95 % confidence interval (1.56; 5.81). In boys, ERR/Gy was higher than...
This paper continues a series of publications that analyze the impact radiation on incidence circulatory system diseases in cohort Russian recovery operation workers (liquidators) and presents results analysis cardiovascular disease (CVD) incidence. The studied consists 53,772 liquidators who arrived Chernobyl accident zone within first year after (26 April 1986 to 26 1987). individual doses varied from 0.0001 Gy 1.42 Gy, mean external whole body dose was 0.161 Gy. A total 27,456 cases CVD...
The paper presents an analysis of the incidence cerebrovascular diseases (CeVD) in cohort Russian workers involved recovery tasks after Chernobyl accident. studied consists 53,772 operation (liquidators) who arrived zone accident within first year this (26 April 1986–26 1987). mean external whole body dose was 0.161 Gy, while individual doses varied from 0.0001 Gy to 1.42 Gy. During follow-up period 1986–2012, a total 23,264 cases CeVD were diagnosed as result annual health examinations. A...
Context: Increased oxidative stress is a significant part of pathogenesis smoking-related cancer. Aim: The study aims to investigate changes in antioxidant status induced by chronic cigarette smoking cancer patients and healthy subjects. Setting Design: We examined the venous blood samples 54 subjects, both smokers (25) non-smokers 50 with cancer, (34) non-smokers. Materials Methods: measured activities five (AO) enzymes: glutathione peroxidase, transferase (GST), reductase, superoxide...
Because of fast growing medical radiation use, estimating possible late health effects radiation, including potential cancer risk, is an issue substantial interest. Since physicians make the decision to order or perform a radiological procedure, it very important provide them with objective information about radiation-associated risks. Methodology for risks based on recommendations ICRP Publication 103 presented in paper. Organ doses, age, and gender are used as basic parameters. An example...

Multiple CT scans are often done on the same patient resulting in an increased risk of cancer. Prior publications have estimated risks a population basis and using effective dose. Simply adding up from single does not correctly account for survival function. A methodology estimating personal radiation attributed to multiple imaging organ doses is presented this article. The magnitude attributable fraction possible development radiation-induced cancer indicates necessity strong clinical...
The authors compare radiation risks of potential cancer following diagnostic exposure evaluated with the use organ and effective doses. Lifetime attributable risk values CT scanning are estimated ICRP (Publication 103) models Russian national medical statistics data. For populations under age 50, using doses usually differs from that by <30 %. In older populations, difference can be up to a factor 3. Calculated lifetime for particular organs presented as well.

Purpose: The main purpose of the research is to define group radiation risk (GRR) on incidence hypertension among Russian recovery operation workers Chernobyl accident (liquidators).
 Material and methods: object cohort liquidators with known individual doses external gamma exposure all body. Definition GRR based assessment excess relative (ERR) (RR) in observed 106 thousand liquidators, having average accumulated dose body 0.11 Gy maximum about 1 Gy.
 Results: From 1986 2012 this...
In the absence of man-made sources ionizing radiation health risks are related primarily to non-malignant diseases, particularly circulation diseases. However, radiation-induced non-cancer diseases can make a notable contribution overall radiation-associated detri-mental effects human health. The impacts harm caused by induced and cancer comparable. That is why study diseas-es for Chernobyl cleanup workers actual scientific problem, it also essential protection. aim estimate incidence...
Leukemia incidence in the cohort of Russian male recovery operation workers (liquidators) was estimated at 78110 people for follow-up period 1986-2014. The average age liquidators time entry into zone works liquidation Chernobyl accident 34 years. Radiation risk leukemia (with exception chronic lymphocytic leukemia) analyzed who had official data on individual dose external gamma radiation entire body accumulated over work. During period, 157 cases were detected leukemia). Collection and...
The current study has two aims: the first is to quantify difference between radiation risks estimated with use of organ or effective doses, particularly when planning pediatric and adult computed tomography (CT) examinations. second aim determine method calculating doses cancer risk using dose-length product (DLP) for typical routine CT In both cases, radiation-induced from medical examinations were evaluated as a function gender age. Lifetime attributable values scanning ICRP (Publication...
The paper presents analysis of different factors affecting the uncertainty model for estimating ra-diation risk from computed tomography (CT). Uncertainties in radiation doses estimates caused by measurement (instrumental) errors or used dose estimation methods, size scanned area and type CT scanner. due to a scan may cause uncertainties as well. Data calculating equivalent individual organs tissues lifetime cancer development routine testing were updated. Conversion DLP, measure patient...
The paper considers radiation risks of solid cancer incidence and mortality, as well risk leu-kemia (other than chronic lymphocytic leukemia) among Russian Chernobyl cleanup workers (liquidators). study the cohort liquidators carried out at National Radiation Epidemiological Registry (NRER) was based on follow-up data collected from 1992 over 2019. size exceeded 65 thousand people, their av-erage age time entering exclusion zone 34 years, average external gamma dose received by during work...
