Emerging themes and future directions in space radiation health research: a bibliometric exploration from 2013 to 2022
Abstract
The impact of space radiation on health (SRHE) is extensive and significantly influences public health and space operations, making it essential to analyze global collaboration networks and track developmental trends over the last decade. However, bibliometric analysis in this area remains limited. This study aims to outline publication trends, citation patterns, major journals, key authors, institutional and national collaborations, and to explore emerging themes and future directions. A bibliometric analysis was conducted using CiteSpace, Bibliometrix in R, and VOSviewer on SRHE research from the Web of Science Core Collection up to November 12, 2023. The analysis included 390 records from 4,857 journals, involving 1,918 authors across 701 institutions in 53 countries. The predominant publications were Articles and Review Articles in Life Sciences and Biomedicine, with a notable publication surge in 2020. The most cited work was by Li et al. (2017), with Cucinotta F.A. as the most prolific author. The USA led in publications, citations, and collaboration strength, followed by Germany and China. Key journals include Radiation Research, Plos One, Life Sciences in Space Research, and Health Physics. Research has focused on radiation exposure effects, DNA damage repair, astronaut health risks, and radiation protection, with emerging trends in microgravity, astrobiology, and lifespan research, which examines the biological, psychological, and social aspects of aging and the…
