Status of Ecosystems in Radioactive Waste Reservoirs of the Mayak Production Association in 2009

Health Physics, 2012
Liquid radioactive waste from the Mayak Production Association (Chelyabinsk Region, Russia) is contained in industrial reservoirs (R-11, R-10, R-4, R-17, and R-9) that have different levels of radioactive contamination, increased from R-11 to R-17.

Development of an Inhalation Intake Model for 241Am Based on Mayak Production Association Worker Data

Health Physics, 2013
Americium-241 is a significant radiation hazard at facilities that handle or reprocess spent nuclear fuels. An inhalation intake model for 241Am was developed using autopsy data obtained from former workers at the Radiochemical and Plutonium Production Plants at the Mayak Production Association (Mayak PA), Ozyorsk, Russia.

Accumulation, Organ Distribution, and Excretion Kinetics of 241Am in Mayak Production Association Workers

Health Physics, 2013
Americium-241 (²⁴¹Am) is the second most significant radiation hazard after ²³⁹Pu at some of the Mayak Production Association facilities. This study summarizes current data on the accumulation, distribution, and excretion of americium compared with plutonium in different organs from former Mayak PA workers.

CALCULATED ORGAN DOSES FOR MAYAK PRODUCTION ASSOCIATION CENTRAL HALL USING ICRP AND MCNP

Health Physics, 2003
As part of an ongoing dose reconstruction project, equivalent organ dose rates from photons and neutrons were estimated using the energy spectra measured in the central hall above the graphite reactor core located in the Russian Mayak Production Association facility.

UNCERTAINTIES ANALYSIS OF DOSES RESULTING FROM CHRONIC INHALATION OF PLUTONIUM AT THE MAYAK PRODUCTION ASSOCIATION

Health Physics, 2005
A method is presented to determine the uncertainties in the reported dose due to incorporated plutonium for the Mayak Worker Cohort. The methodology includes errors generated by both detection methods and modeling methods. To accomplish the task, the method includes classical statistics, Monte Carlo, perturbation, and reliability groupings ...

Reconstruction of the contamination of the Techa River in 1949–1951 as a result of releases from the “MAYAK” Production Association

Radiation and Environmental Biophysics, 2012
More accurate reconstruction of the radioactive contamination of the Techa River system in 1949-1951 has been made on the basis of refined data on the amounts and the rate of discharge of radionuclides into the Techa River from the Mayak Production Association; this has led to the development of a modified Techa River model that describes the transport

Registry for chronic radiation syndrome in a worker cohort of the Russian nuclear enterprise, Mayak Production Association

Journal of Radiological Protection, 2019
Abstract A registry for chronic radiation syndrome (CRS), a deterministic effect of chronic exposure to external and/or internal radiation at doses and dose rates exceeding thresholds for tissue reactions, was established within a medical and dosimetry database known as ‘Clinics’, of the Southern Urals Biophysics Institute at the ...

RECONSTRUCTION OF RADIONUCLIDE CONTAMINATION OF THE TECHA RIVER CAUSED BY LIQUID WASTE DISCHARGE FROM RADIOCHEMICAL PRODUCTION AT THE MAYAK PRODUCTION ASSOCIATION

Health Physics, 2000
Because of its importance to reconstructing radiation doses for ongoing epidemiological studies, a feasibility study was undertaken to determine if the source term of radioactive materials released to the Techa River from the Mayak Production Association, the first facility in the former Soviet Union for the production of plutonium, could be ...

EXTRAPULMONARY ORGAN DISTRIBUTION OF PLUTONIUM IN HEALTHY WORKERS EXPOSED BY CHRONIC INHALATION AT THE MAYAK PRODUCTION ASSOCIATION

Health Physics, 2002
The systemic distribution of plutonium was determined for "healthy" workers who chronically inhaled plutonium at the radiochemical plants of the Mayak Production Association. The data were obtained by radiochemical analysis of soft tissues and bones samples collected upon autopsy of 120 workers who died from acute coronary diseases and accidents.

REEVALUATION OF WATERBORNE RELEASES OF RADIOACTIVE MATERIALS FROM THE MAYAK PRODUCTION ASSOCIATION INTO THE TECHA RIVER IN 1949–1951

Health Physics, 2012
The Mayak Production Association was the first site for the production of weapons-grade plutonium in Russia. Early operations led to the waterborne release of radioactive materials into the small Techa River. Residents living downstream used river water for drinking and other purposes.
