Evaluation of In Utero Doses from Maternal Ingestion of Strontium Radioisotopes at the Techa River

چکیده
A cohort of persons exposed in utero due to radioactive contamination of the Techa River (Southern Urals, Russia) in the early 1950s represents a unique opportunity for studying radiation risks from chronic exposures in early life. Bone-seeking strontium radioisotopes were the main contributors to haemopoietic tissue doses received in utero from maternal ingestion of radionuclides before and during pregnancy. Collaborative studies have been conducted between the Urals Research Center for Radiation Medicine, UK Health Protection Agency and University of Florida to provide the best possible evaluations of the doses from strontium radioisotopes incorporated during foetal development to support companion epidemiological studies of the Techa River population. This paper provides insights to the dose reconstruction efforts and presents the first estimates of doses of in utero exposure to strontium radionuclides for children born in Muslyumovo located on the Techa River.

Nuclear techniques for direct assessment of internally deposited radionuclides are essential for monitoring and dosimetry of members of the public exposed due to radiation accidents. Selection of the methods for detection of internal contamination is determined by nuclear-physical characteristics of the deposits. For the population living in settlements located along the Techa River contaminate...

BACKGROUND Previous studies have shown that acute external in utero exposure to ionizing radiation can increase cancer risk. It is not known whether chronic exposure at low dose rates, including due to radionuclide intake, influences the lifetime risk of solid cancers in the offspring. The objective of this study was to investigate solid cancer risk after in utero irradiation. METHODS Cancer ...

INTRODUCTION The ICRP models used in radiation protection to estimate doses resulting from internal irradiation are based on biokinetic models for different radionuclides. As a rule, a biokinetic model is based on some combination of observations of the behavior of the element in human subjects, of the same element in other mammalian species, chemically similar elements in human subjects and in...
