Risks of most types leukemia from exposure to acute high doses ionizing radiation are well known, but risks associated with protracted exposures, as associations between and chronic lymphocytic (CLL), not clear.
Genomics of radiation-induced damage The potential adverse effects exposures to radioactivity from nuclear accidents can include acute consequences such as radiation sickness, well long-term sequelae increased risk cancer. There have been a few studies examining transgenerational risks exposure but the results inconclusive. Morton et al. analyzed papillary thyroid tumors, normal tissue, and blood hundreds survivors Chernobyl accident compared them against those unexposed patients. findings...
Between 1986 and 1990, several hundred thousand workers, called "liquidators" or "clean-up workers," took part in decontamination recovery activities within the 30-km zone around Chernobyl nuclear power plant Ukraine, where a major accident occurred April 1986. The liquidators were mainly exposed to external ionizing radiation levels that depended primarily on their work locations time after when was performed. Because individual doses often monitored inadequately not at all for majority of...
The increased occupational doses resulting from the Chernobyl nuclear reactor accident that occurred in Ukraine April 1986, of Fukushima took place Japan March 2011, and early operations Mayak Production Association Russia 1940s 1950s are presented discussed. For comparison purposes, due to other two major accidents (Windscale United Kingdom 1957 Three Mile Island States 1979) main plutonium-producing facility (Hanford Works) also covered but less detail. Both for routine at Mayak,...
Although transgenerational effects of exposure to ionizing radiation have long been a concern, human research date has confined studies disease phenotypes in groups exposed high doses and dose rates, such as the Japanese atomic bomb survivors. Transgenerational parental irradiation can be addressed using powerful new genomic technologies. In collaboration with Ukrainian National Research Center for Radiation Medicine, US Cancer Institute, 2014-2018, initiated alterations study among children...
Andreeva Bay in northwest Russia hosts one of the former coastal technical bases Northern Fleet. Currently, this base is designated as branch Northwest Center for Radioactive Waste Management (SevRAO) and a site temporary storage (STS) spent nuclear fuel (SNF) other radiological waste generated during operation decommissioning submarines ships. According to an integrated expert evaluation, most dangerous facility Russia. Environmental rehabilitation currently progress supported by strong...
This paper describes dose reconstruction for a joint Ukrainian-American case-control study of leukemia that was conducted in cohort 110,645 male Ukrainian cleanup workers the Chornobyl (Chernobyl) accident who were exposed to various radiation doses over 1986–1990 time period. Individual bone-marrow due external irradiation along with respective uncertainty distributions calculated 1,000 subjects using RADRUE method, which employed personal history data collected course an interview subject...
Radiation doses of parents exposed from the Chornobyl accident as cleanup workers or evacuees were estimated in National Cancer Institute-National Research Center for Medicine trio (i.e. father, mother, offspring) study aimed at investigating radiation effects on germlinede novomutations children well other outcomes. Paternal (testes) and maternal (ovaries) gonadal calculated along with associated uncertainty distributions following exposure pathways: (a) external irradiation during mission,...
Abstract Thyroid doses were estimated for 607 subjects of a case-control study thyroid cancer nested in the cohort 150,813 male Ukrainian cleanup workers who exposed to radiation as result 1986 Chernobyl nuclear power plant accident. Individual due external irradiation, inhalation 131 I and short-lived radioiodine radiotellurium isotopes ( 132 I, 133 135 131m Te, Te) during mission, intake residence contaminated settlements calculated all subjects, along with associated uncertainty...
In compliance with the fundamentals of government's policy in field nuclear and radiation safety approved by President Russian Federation, Russia has developed a national program for decommissioning its legacy. Under this program, State Atomic Energy Corporation 'Rosatom' is carrying out remediation Site Temporary Storage spent fuel (SNF) radioactive waste (RW) at Andreeva Bay located Northwest Russia. The short term plan includes implementation most critical stage remediation, which...
Radiation doses received by workers during their movement within areas contaminated as a result of events and activities, leading to emergency or existing exposure situations, may provide substantial contribution total external remediation work. This paper describes an approach minimise worker in these circumstances, based on graph theory. The several tasks, including: searching for route with the lowest dose, optimal bypass given set control points road network coverage. Classical theory...
The Coastal Technical Base (CTB) №569 at Andreeva Bay was established in the early 1960s and intended for refueling of nuclear submarine reactors temporary storage spent fuel (SNF) radioactive waste (RW). In 2001, base transferred to Russian Ministry Atomic Energy site remediation began. paper describes detail radiation situation change technical from 2002-2016, period preparation most critical phase remedial work: removal assemblies. analysis aggregated indicators data mining were used....
A method has been developed for solving the Fredholm equation in barrier geometry reconstructing surface activity density (SAD) from results of measuring ambient dose equivalent rate (ADER). Inclusion means that takes into account shielding effect buildings and structures on contaminated site. The was based representation industrial site, radiation fields form a raster use visibility matrix (VM) cells to describe geometry. applied hypothetical site with size 200 × conventional units four...
This original study aims to quantify the human factor uncertainties in radiation doses for Chernobyl cleanup workers that are associated with errors direct or proxy personal interviews due poor memory recall a long time after exposure. Two types of external irradiation during mission were calculated independently. First, “reference” dose, was using historical description activities reported by 47 shortly completion mission. Second, “current” dose information and respective 24 proxies...
This article presents a method for assessing the radionuclide surface contamination density (SCD) on open sites and in premises of radiation hazardous facility based measurements ambient dose equivalent rate (ADER). The is intended use at initial stage assessment environment facilities. assessed SCD given location can differ from directly measured that location, since sources located distributed by depth contribute to ADER value. makes it possible estimate with reasonable accuracy without...
This paper deals with classification of dose distributions nuclear workers based on antikurtosis (Q) and entropy coefficients (K) their relationship presented in QK-diagrams. It is shown that determination the most appropriate distribution to adopt, for a specific data set wide range input data, requires building analysing QK-diagrams logarithms individual doses. Actual emergency occupational exposure situations were then considered, as well doses one day work during clean-up routine...
A method for reconstructing surface activity density (SAD) maps based on the solution of Fredholm equation has been developed and applied. The construction SAD was carried out site temporary storage (STS) spent fuel radioactive waste (RW) in Andreeva Bay using results measuring campaign 2001-2002 sheltering solid RW measurements 2021. solved two versions: under conditions a barrier-free environment taking into account buildings structures located industrial STS Bay. Lorenz curves were...
