THE DEVELOPMENT OF THE PLUTONIUM LUNG CLEARANCE MODEL FOR EXPOSURE ESTIMATION OF THE MAYAK PRODUCTION ASSOCIATION, NUCLEAR PLANT WORKERS

open access: closedHealth Physics, 2002
The purpose of this study was to develop a biokinetic model that uses urinary plutonium excretion rate data to estimate the plutonium accumulation in the human respiratory tract after occupational exposure. The model is based on autopsy and urinalysis data, specifically the plutonium distribution between the respiratory tract and the remainder of the ...

Artificial radionuclides association with bottom sediment components from Mayak Production Association industrial reservoirs

Journal of Environmental Radioactivity, 2021
About ten years have passed since the last published report in Russian on the speciation and distribution features of radionuclides in the bottom sediment of Production Association (PA) "Mayak" (further mentioned as Mayak) artificial reservoirs. Herein, the desorption parameters of 137Cs, 90Sr, 241Am, and 238,239+240Pu and their association with bottom

Incidence risks for subtypes of heart diseases in a Russian cohort of Mayak Production Association nuclear workers

Radiation and Environmental Biophysics, 2022
Heart diseases are one of the main causes of death. The incidence risks were assessed for various types of heart diseases (HDs) in a cohort of Russian nuclear workers of the Mayak Production Association (PA) who had been chronically occupationally exposed to external gamma and/ or internal alpha radiation.

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.

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.

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 ...
