Overview of current situation and future development of radiation biodosimetry study / 中华放射医学与防护杂志

ABSTRACT

Radiation biodosimetry is an important part of radiation medicine. Some new discoveries and progresses have been made in radiation biodosimetry studies in recent years. Cytogenetic method represented by chromosome aberration analysis as the golden standard of radiation biodosimeter is being transformed to automate analysis, and a number of international, regional and national laboratory networks of radiation biodosimetry are being established. As a widely acceptable molecular marker of DNA damage,γ-H2AX has made rapid progress in radiation dose estimation. Based on the expressions of protein and genes, further advancements have been made in the studies of metabolites and miRNAs. At the same time, with the development of proteomics technology, there are some breakthroughs in the study of using molecular expression profiling to evaluate radiation dose. The research progresses of radiation biodosimetry is reviewed in this paper.
